Multi-objective optimization remains a significant and realistic problem in engineering. A trade-off among conflicting objectives subject to equality and inequality constraints is known as the Pareto Front. The size problem is common to multi-objective optimization. Recently, several multi-objective optimization techniques have been developed; each technique has its own and different characteristics rather than others. This involves search techniques, selection methods, preferences made by the decision makers, an optimization framework, fitness evaluation, mutation or crossover methods, the nature of the problem and constraints, and the degree of complexity. Moreover, classification of problems into static and dynamic further attempts to balance some criteria such as diversity, coverage, and convergence. This paper provides an elaboration on all multi-objective optimization techniques, and shows the drawbacks addressed in the literature, which will help researchers’ understanding of the various formulations in the field.
Multi-objective optimization results in a tradeoff between local and global optimal solutions, influenced by numerous attractors within the solution space. This complexity complicates the task for optimization algorithms [1], particularly in scenarios where the importance of objectives varies among decision makers. In multi-objective optimization, multiple conflicting goals make it impossible to identify a single best solution without knowing the decision makers’ preferences, as all trade-off solutions are equally optimal and important [2][3].
In optimization problems, decision-makers usually assign preferences to reflect the importance of different objectives using various techniques (a priori, a posteriori, interactive, or no-preference). However, in multi-criteria optimization involving qualitative aspects like aesthetics—where preferences are unclear—resulting trade-off solutions may seem unsatisfactory and hinder creativity or design distinctiveness [4]. In scenarios where some objectives are more important than others, prioritizing these objectives is essential. Lexicographic Goal Programming is a common method used to solve such problems by addressing goals in order of their importance.
It ranks the importance of objectives using strategic planning by breaking down objectives into several levels of proactive priorities [5]. Hence, optimization formulations can be categorized into three different categories: no preferences, preference-based (weighing methods), and Prioritization, which utilizes a prioritizing strategy to assign full relative priority to the higher-level ranked objective; afterwards the next rank’s objective, The goal of the multi-decision-maker needs prioritizing problem is to determine the optimal ranking that considers the ratings of each decision-maker separately. Decision-makers must first determine alternative global rankings based on their opinions and then choose the final ranking using a contextual and strategic data-driven process [6].
It is thought that an optimization method may be appropriate for one problem but not for another; in other words, the ability of an optimization method to solve an optimization problem and generate high-quality tradeoff solutions depends on a variety of factors, including search strategy, decision-maker preferences, optimizer framework, selection process, fitness estimation method, degree of complexity, and the point or phase at which a human interacts to enter his preferences [3], in the following sections classification of Multi objective optimization methods will be classified with respect to the aforementioned aspects.
2. Multi-Objective Search Techniques for Optimization
Figure 1 demonstrates the three main categories into which optimization search methods can be generally separated: classical, meta-heuristic, and enumerative. The two primary types of classical algorithms are gradient-based and direct search, which are both known for being accurate methods that guarantee the best possible result. These serve as the cornerstone for the creation of meta-heuristic methods. However, these techniques have a limited scope in practical applications [7]-[9]. Enumerative searches are deterministic, but they are distinguished here because they don’t use heuristics. It is the simplest one; it systematically explores the entire solution space. They take into account every potential answer within a predetermined search space. In which the solution is evaluated, however, it is easily seen that this technique is inefficient or even infeasible as search spaces become large and it takes a longer time for large problems [7][8].
Meta-heuristic methods are best for dealing with real-world problems in several fields; it can serve in engineering, management, politics, and others, and can be applied for discontinuous, large-dimensional, multi-modal problems and can even be used to solve black box optimization problems without understanding the problem physics. An obvious drawback beck that it is unable to provide an exact result. It can be categorized into probabilistic or stochastic and deterministic-based approaches. Metaheuristic stochastic algorithms use the Monte Carlo method or random number generation for initialization, creating uniform pseudo-random sequences based on the uniform probability distribution [10]. Deterministic meta heuristics address optimization problems by applying preset judgments, guaranteeing that the result stays constant [9]. Deterministic meta-heuristic-based search is simple and comprehensible, while the stochastic approach is complex and incomprehensible [11].
Greedy, Hill climbing, Bound and Branch search technique, Branch & Bounds [7]; depth-first search [12][13], breadth-first search [13], Best-first search [12], and calculus-based search technique [13] are well-known techniques under the Deterministic-based Meta Heuristic family. These methods vary in their approach and suitability depending on the problem at hand, whether it involves searching through discrete states (DFS, BFS, Best-First) or optimizing continuous functions (Calculus-Based). Every technique has advantages, and the selection of a particular strategy is dependent on the specific needs and features of the optimization problem [14].
The hill-climbing approach, widely used among human problem solvers, focuses on local optimization. It derives its name from climbers aiming to reach the mountain peak swiftly by choosing the steepest ascent path from their current location. Similarly, when adjusting the knobs of a television to achieve a better image, each knob is turned sequentially, maximizing progress toward the desired quality before moving to the next. This method hinges on continuously evaluating image quality relative to a benchmark and making incremental improvements based on local data, ensuring gradual enhancements in the most promising direction [14].
Hill-climbing is popular due to its low computational cost; it doesn’t require remembering past steps. It works by always choosing the most promising local option. However, this simplicity has downsides: it can get stuck at local maxima, follow misleading paths, or revisit fewer promising options. Since it doesn’t backtrack, it’s called an irrevocable method. Hill-climbing performs better when the evaluation function is accurate and when operators are commutative, meaning their order doesn’t affect outcomes, ensuring the solution can still be reached, even if delayed. This makes it useful for problems like the least spanning tree, though designing the right operators can be challenging [14].
Branch and Bound is a systematic search technique for solving optimization problems by partitioning the solution space and pruning regions that cannot yield better solutions than the best one found so far. It is used when either exhaustive search is too expensive or greedy/local methods are not able to discover the global optimum [14].
Branching the problem and dividing it into smaller subproblems (branches), and bounding for each subproblem, a bound (the best possible solution in that branch) is computed. If this bound is worse than the best-known solution, we can prune (discard) that branch. Pruning discards subproblems that can’t result in a better solution. Search Tree: Problems are represented as nodes in a tree. The root node is the original problem; children are subproblems [14].
Depth-First Search (DFS) investigates each branch as far as feasible before backtracking. Commonly used in graph traversal problems to explore as deeply as much as feasible along each path before backtracking. It is advanced in memory efficiency as it explores deeply, suitable for problems with a large state space [14].
Breadth-First Search (BFS) explores all neighbor nodes at the present depth level before moving on to nodes at the next depth level. Effective for finding the graph’s unweighted shortest path, or when all paths need to be explored systematically. It is advanced in Guarantees the quickest route in terms of number of edges [14].
Best-First Search chooses the node with the most promise according to some heuristic, typically the estimated distance from the goal. Widely used in informed search algorithms like A*, where the heuristic guides the search towards the goal efficiently. Advances in efficiency in finding a solution quickly based on the Calculus-Based Optimization, which uses mathematical calculus (derivatives, gradients) to optimize continuous functions. Applied in a number of fields, such as engineering, economics, and physics, to find optimal solutions to problems described by mathematical functions. Provides exact solutions when the objective and constraint functions are differentiable, allowing for precise optimization in continuous domains [14].
Stochastic search is divided into two categories: population-based methods and single-solution methods. In the single solution the work only to modify a single solution, until reaching a defined criterion [15]. In contrast, population-based methods alter and modify a set of solutions during optimization. However, throughout the process of optimization, a collection of solutions is altered and transformed using population-based strategies [16]. Local search, Tabu search, etc., are some examples of stochastic single-solution-based methods [17].
One of the significant issues that faces the meta heuristic optimizers in stochastic search is highly sensitive to the initial population’s characteristics. Population-based metaheuristic algorithms have different capacities to arrive at a global optimum when the initialization method is altered [15]. In this search technique, it is possible for the same starting solutions to lead to various final answers when using probabilistic approaches since they employ random rules throughout search. In a short length of time, these strategies produce solutions of excellent quality [16].
Single-objective-based techniques can only produce the best results for one competing objective at a time and have a single objective function and a unique optimal solution. Multi-objective methods deal simultaneously with several objectives and offer Pareto-optimal solutions [15][18]. Evolutionary and swarm-based approaches, mathematical programming, and hybrid algorithms are the four primary groups into which multi-objective techniques fall. Hybrid algorithms combine the concepts of swarm and evolutionary algorithms or others [15]. The integration of different methods allows the algorithm to improve each component and mitigate its weaknesses. Here are a few ways in which multi-objective algorithms can be hybridized [19][20]:
Integrating Local Search with Evolutionary Algorithms: Multi-objective algorithms like the Strength Pareto Evolutionary Algorithm 2 (SPEA2) and the Non-dominated Sorting Genetic Algorithm II (NSGA-II) can be enhanced by incorporating local search techniques. Local search refines solutions in the vicinity of the current population, improving both the convergence to the Pareto front and the diversity of the solutions.Hybrid algorithms can incorporate machine learning methods to enhance decision-making and guide the search process. For instance, reinforcement learning or surrogate modeling can predict the performance of candidate solutions, enabling us to concentrate on the most promising regions inside the search space.Integrating Swarm Intelligence with Evolutionary Algorithms: Combining multi-objective algorithms with swarm intelligence methods, such as Particle Swarm Optimization (PSO), results in hybrid approaches like Multi-Objective Particle Swarm Optimization (MOPSO). This integration enhances the efficient exploration of the area under search.Hybrid Algorithms: These approaches combine evolutionary algorithms with mathematical programming methods, such as linear or integer programming, to enhance their ability to address specific constraints or objectives effectively.
Evolutionary algorithms are techniques inspired by the principles of natural evolution. They allow for the generation of a group of trade-off solutions in a single run while requiring significantly less computational power to identify these solutions [15]. Convergence, variety or diversity, and coverage are the fundamental objectives [19]. Evolutionary algorithms are distinguished in three main categories: decomposition-based, indicator-based, and dominance-based [21]. The Pareto dominance principle is used to determine the fitness of solutions in dominance-based algorithms.
The Normal Boundary Intersection (NBI) is a well-known example of a posteriori technique based on mathematical programming [22], Modified Normal Boundary Intersection (NBIm) [23], Normal Constraint (NC) [24], and Successive Pareto Optimization (SPO) [25]. And Directed Search Domain (DSD) [26], which builds many scalarizations to tackle the multi-objective optimization issue. A Pareto optimum solution, either locally or globally, is produced by the answer to each scalarization. In Figure 4, the NBI, NBIm, NC, and DSD scalarizations are designed to produce uniformly distributed Pareto points that provide a decent approximation of the actual Pareto point set.
Swarm-based techniques leverage the intelligent behavior of self-organizing and decentralized systems inspired by biological phenomena. These algorithms are well-suited for solving both single-objective and multi-objective optimization problems. One of the most renowned swarm-based approaches for multi-objective optimization is Multi-Objective Particle Swarm Optimization (MOPSO) [27], Multi-Objective Ant Colony Optimization (MOACO) [28], and Multi-Objective Marine Predator Algorithm (MMPOA) [29]. Multi-objective Whale Optimization Algorithm (WOA) [30], and Multi-objective Spotted Hyena Optimization (MOSHO) [31]. These techniques successfully minimize the objective function without becoming trapped in local minima (Figure 2).
Figure 2. Swarm-based optimization algorithms.
Swarm-based approaches rely on influencing individual behavior by local or global individuals on others, similar to the crossover operator in evolutionary algorithms. They incorporate potential solutions traveling via hyperspace, allowing individuals to benefit from past experiences. One of the most significant accomplishments of PSO is its effectiveness in solving both discrete binary and continuous nonlinear optimization problems [32].
Through interactions at the local level, the self-organizing characteristic of a swarm system facilitates the evolution of solutions at the global level.
3. Classification of Multi-Objective Optimization Based on Preferences
There are three main approaches to optimization with multiple objectives, depending on when the decision maker interacts at which provides additional preference information [4][10][11][33][34].
- A priori method requires the decision-maker to provide additional preferences, such as objective weights, before the optimization process begins. In other words, preference information must be incorporated into the mathematical programming problem prior to initiating the solution search [10].
- The posteriori method involves the user expressing their preferences after gaining an understanding of the trade-offs among non-dominated alternatives. These approaches can be generally divided into two categories: those that employ mathematical programming techniques and those based on Evolutionary Multi-objective Optimization (EMO) algorithms. In these methods, the decision-maker evaluates all or a subset of the Pareto optimal options and selects what they consider to be the best or most suitable solution [4][10][34].
-In interactive approaches, the decision-maker provides preferences during each iteration, gradually guiding the process toward the final solution. The execution of this approach involves refining objective functions and constraints by incorporating user feedback on preferences at different stages of the process [4][10][34].
In addition to the three previously mentioned approaches, multi-objective optimization (MOO) can also produce solutions that do not rely on preference-based trade-offs. However, such solutions are less suitable for multi-criteria optimization, which often considers qualitative factors like aesthetics. This limitation can hinder one of the most vital aspects of design: originality [34]. Examples of non-preference-based methods include Gradient Descent, a commonly used optimization technique, as well as Simulated Annealing, Particle Swarm Optimization (PSO), Ant Colony Optimization (ACO), and Random Search. Random Search, which involves sampling points randomly from the solution space and evaluating their performance, can be surprisingly effective for certain optimization issues, particularly when the solution space is poorly understood.
Classical single or multi-objective optimization techniques are frequently used to support the priori approach, while the posteriori method necessitates intriguing alterations to theorems and optimization algorithms. In real-world applications, interactive methods are quite fascinating, although they usually rely on computational techniques employed in a priori and a posteriori approach and combine them with intermediate phases of preference elicitation [34].Figure 3 shows the numerous kinds of multi-objective optimization methods based on the role of humans in the optimization process [34].
As illustrated in Figure 4, the NBI, NBIm, NC, and DSD scalarization methods are formulated to generate uniformly distributed Pareto points, offering a reasonable approximation of the true Pareto front.
Figure 3. Grouping multi-objective optimization techniques according on how humans are involved in the optimization process.
Figure 4 gives examples of optimization methods under each search classification; the most well-known a priori approaches are the utility function method, the lexicographic method, and goal programming, and others [33].
Figure 5 illustrates schematically the priori approach, which begins with the selection of preference vector w using higher-level information. The composite function is then created using the preference vector, and a single-objective optimization method is applied to optimize it in order to get a single solution. The method is applicable to find several trade-off solutions by using an alternative preference vector and repeating the steps [33].
Figure 4. Goal-oriented multi-objective optimization methods and algorithms classification.
Figure 5. Schematic of a priori preference-based multi-objective optimization procedure (Classical MOO Procedure).
Tradeoff results/solutions obtained by the preference-based procedure is very sensitive to the relative preference vector used in forming the composite function. Aside from the problem, it is obvious that determining a relative preference vector is highly subjective and challenging [33].
Classical optimization mostly works according to the priori preference-based approach. Starting with the weighted sum approach, the ε-constraint method, Tchebycheff methods [9], value function methods and goal programming methods and other methods will be presented below [33].
As described above, since the classical procedure requires higher preference information before starting the optimizer, it could be categorized as a priori multi-objective optimization [34]. The Weighted Sum Method is one of the priori approaches examples; it combines multiple objectives into a single objective function by assigning a user-defined weight to each one and multiplying accordingly. This approach is the simplest and most widely used traditional technique. It’s the most intuitive method for addressing multiple objectives, as it involves minimizing a weighted total. For example, if the goals are to lower production costs and reduce material waste during manufacturing, this method naturally balances the trade-offs between the two [33].
The vector of objectives function must be normalized in order to solve the issue of varying order of magnitude for distinct objective functions before being transformed into a single weighted objective function.
This strategy can be outlined as follows:
Minimize f ( x ) = ∑ m = 1 M w m f m ( x )
Subject to g i ( x ) ≥ 0 , j = 1 , 2 , ⋯ , J
hk(x)=0,k=1,2,⋯,Kxi(L)≤xi≤xi(U),i=1,2,……,n
Weighted Metric Methodsintegrates numerous objectives into a single objective can be used instead of a weighted sum of the objectives. Weighted metrics, such as l p and l ∞ distance measurements, are frequently employed for this purpose. The weighted l ∞ distance measure of any solution x from the ideal solution z* can be minimized for non-negative weights as follows:
lp(x)=∑m=1Mwm|fm(x)−zm*|1/p,
Subject to g i ( x ) ≥ 0 , i = 1 , 2 , ⋯ , J
hk(x)=0,k=1,2,⋯,Kxi(L)≤xi≤xi(U),i=1,2,⋯,n
Figure 6 shows that, when p = 1, the resultant problem corresponds to the weighted sum technique. When p = 2, the weighted Euclidean distance from the ideal point of any point in the objective space is reduced [33].
Generally, when using higher value of p , the goal is to reduce the largest deviation | f m ( x ) − z m * | , this is called weighted Tchebycheff metric [3][9].
Minimize l ∞ ( x ) = ∑ m = 1 M max m = 1 M w m | f m ( x ) − z m * | ,
Subject to g i ( x ) ≥ 0 , i = 1 , 2 , ⋯ , J
hk(x)=0,k=1,2,⋯,Kxi(L)≤xi≤xi(U),i=1,2,⋯,n
The figures below for p = 1, p = 2, p = ∞
Figure 6. Effect of p parameter on Pareto frontier.
It is not possible to find every optimal solution when p = 1, p = 2, where all optimum solutions can be found if we apply the weighted Tchebycheff metric, which should satisfy the following theorem [33].
Theorem3 Let x* be a Pareto-optimal solution. Then the weighted Tchebycheff problem can be solved by x’ if there is a positive weighting vector shown in the above equation, where the reference point is the utopian objective vector z**.
It’s also critical to keep in mind that, as p increases, the problem can no longer be differentiated, which means that many gradient-based approaches cannot be used to identify the minimum solution to the single-objective optimization problem [3].
Normalizing the objective functions is essential when using this method since different objectives may require values with different orders of magnitude, and understanding the lowest and maximum function values for every target is the main challenge faced using this method. Additionally, the real solution z* is needed for this strategy to work. Consequently, prior to optimizing the l p metric, each of the M objectives must be improved independently [3].
εConstraint Methodis shown in Figure 7. It may address the non-convex objective space; this is a limitation of the weighted approach. To address this, Haimes et al. (1971) suggested reformulating the MOOP by retaining a single objective while constraining the others to user-defined values. The revised problem is expressed as follows [3]
Minimize f μ ( x ) ,
Subject to f m ( x ) ≤ ϵ m , m = 1 , 2 , ⋯ , M and m ≠ μ
Figure 8. The proposed correlated weighted metric method with p = 2.
The parameter ϵ m represents an upper bound of the value of f m ( x ) and need not necessarily mean a small value close to zero. In this method, one objective is treated as objective function, and the others as constraints f m ( x ) ≤ ϵ m , if ϵ m = ϵ c divides the objective space into two different parts, f 1 > ϵ c , and f 1 ≤ ϵ c .
The resulting problem expressed in the preceding equation has a feasible solution that is located in the left section of the objective space. Finding a solution that reduces this viable zone is now the challenge of the resulting problem [3].
The obvious minimum solution is “C”. Using the ε-constraint method, intermediate Pareto-optimal solutions to nonconvex objective space problems can be obtained.
The following theorem proves the ε-Constraint Method’s utility in dealing with either convex or non-convex problems.
Theorem3 The unique solution of the ε-constraint problem stated in equation is Pareto-optimal for any given upper bound vector ∈ = ( ∈ 1 , ∈ μ − 1 , ∈ μ + 1 , ⋯ ∈ M ) T .
Kuhn-Tucker optimality conditions (Deb, 1995) and by using a Lagrange multiplier for μ 1 the constraint.
Using different ∈ M values, different Pareto-optimal solutions can be found. The same strategy can be applied to issues with convex or nonconvex objective spaces.
One obstacle lies in using ε-Constraint Method when choosing ∈ M not between the minimum and maximum function value, thus no feasible solutions will be obtained [3].
Rotated Weighted Metric Method. Alternatively, as shown in Figure 8, the l p metric can be applied with an arbitrary rotation from the ideal point, as opposed to applying it directly as indicated in the weighted metric method. Let us consider the following relationship between the rotated objective reference axes f and the original objective axes f [3].
f˜=Rf
where R is the rotation matrix of size M × M, thus, the modified l p metric becomes
lp˜=(|∑m=1Mwm|fm˜(x)−zm*|p)1/p
By using p = 2, then
[(f(x)−z*)TC(f(x)−z*)]1/p
where,
C=[cosαsinα−sinαcosα]T[w100w2][cosαsinα−sinαcosα]
Different w and α will give different solutions, where w takes the value from 0 to 1, and the angle α from 0 to 90 degrees.
Adapting the Optimal Solution Dynamically
The problem faced l p metric is when p is smaller, it will be challenging to locate some optimum solutions, this difficulty can be overcome also, by update of point z * for every time that a Pareto-optimal solution is found, by this way Ip distance comes closer to Pareto optimal front, and the solutions that aren’t covered before will be easier to be obtained [3].
As shown inFigure 9, with each Pareto-optimal solution discovered thus far, all potential combinations of solutions can be created to produce new candidate ideal solutions. Following that, a candidate solution that does not dominate any of the other alternatives can be chosen as the new z*, Figure 9 showing that by moving z* closer to Pareto front, more Pareto optimal solutions can be found
Figure 9. Effect of z* location on number of optimum Pareto solutions.
Figure 10. Benson’s method.
Benson’s Method is most similar to weighted metric approach, except that the reference solution is assumed to be a viable non-Pareto-optimal solution. The working principle is shown in Figure 10; it depends on a solution z 0 which is generated randomly from the feasible region. Afterwards, the non-negative difference ( z n − f m ( x ) ) of each objective is then evaluated, and their sum is maximized [3];
maximize ∑ m = 1 M max ( 0 , ( z m 0 − f m ( x ) ) ) ,
Maximizing the above objective involves identifying a hypercube with the largest perimeter. The optimal solution to this problem lies on the Pareto-optimal front, as the Pareto-optimal region is located at the limit of what a practical search space is [3].
The method, while superior to the weighted metric, has limitations such as additional constraints to limit the search to the region dominated by the chosen solution z 0 and a non-differentiable objective function, making gradient-based methods challenging to address. Although Ehrgott (2000) modified the formulation for differentiable objective functions also presents equality requirements.
Value Function Method (Utility Function) depends on utilizing the interaction of function value with the others, it allows for interactions between different objectives, where f ( x ) = ( f ( 1 ) , f ( 2 ) , ⋯ f m ( x ) ) . When comparing solutions i and j , if the utility function U ( f i ) > U ( f i ) solution i is selected over solution j . According to Rosenthal (1985), the value function must be significantly decreasing before being employed in multi-objective optimization. This indicates that if one of the objective function values is decreased while the other objective function values remain constant, the preference for a solution must grow. As a result, Miettinen (1999) established the following theorem:
Theorem4
Let the value function U: R M → R be strongly decreasing. Let U attain its maximum at f * . Then, f * is Pareto-optimal.
For the contours shown in Figure 11, solution A is the best fit, as its value function contour is tangential to the Pareto-optimal front. It’s necessary to remember that this approach can only identify one answer at once. By adjusting the value function’s parameters, several Pareto-optimal solutions can be attained [3].
Figure 11. Contours of the value function.
In the utility function, the goal is to maximize the value function as follows: Where U: R M → R for all M objectives
maximize U ( f ( x ) ) ,
Subject to g i ( x ) ≥ 0 , i = 1 , 2 , ⋯ , J
hk(x)=0,k=1,2,⋯,Kxi(L)≤xi≤xi(u),i=1,2,⋯,n
The primary limitation of this approach is that the resultant answer is totally reliant on the value function that was employed. Additionally, the user must create a value function that is globally applicable throughout the whole search space; consequently, there is a risk of utilizing an overly simplistic value function [3].
Min-Max Goal Programming, in this technique, instead of reducing the total weighted deviations from the objectives, the largest deviation within each goal is minimized [3]. This method involves achieving target values for every objective, so that it can be considered as an extension of traditional linear programming [35]. The Mathematical expression of Min-max Goal Programming is as follows:
Mind
Subject to f i ( x ) + n i − p i = b i
αini+βipi≤dx∈Fx≥0,ni,pi≥0,i=1,2,3⋯k
where p i , and n i are the positive and negative deviations from the desired value of the ith objective, d is the largest deviation, and b i is the precise targeted level for the ith goal [35].
Because this technique necessitates selecting weight factors α i and β i , the user is ultimately in control of the technique. This method resembles the weighted Tchebycheff method in several ways, but it substitutes the target solution for the ideal solution [3].
This approach was updated by Zeleny, who suggested a new Goal programming procedure instead of determining the optimum in a system with fixed resources, to construct an optimal system by expanding resources [36]. This method is then called De Novo programming. In the above procedure, the objective is to determine each objective function’s best and worst performances; based on these performances, a suitable solution is then obtained.
This procedure is called a posteriori multi-objective optimization, where the algorithm searches for a minimal set of solutions based on a partial order (usually the Pareto order) within the target space. After generating the set of nondominated solutions, the user then analyzes the trade-offs and selects a preferred solution afterward [34].
There is a key difference between the two methods: priori methods require a preference vector before knowing the outcomes, while posteriori methods use problem data to choose from a set of trade-off solutions. A posteriori approaches are generally more systematic and practical, but if a reliable preference vector is available, then priori methods are sufficient and more direct.
In Figure 4, the posteriori approaches are divided into two main categories: mathematical programming techniques and algorithms for Evolutionary Multi-objective Optimization (EMO), NBI, NC, SPO, DSD are examples for the mathematical programming techniques, while NSGA II, NSGA III, SPEA-2, PSO, SA, and MOGA are good examples for the evolutionary algorithms [14].
As shown in Figure 12, Step 1 (downward and vertically) finds multiple and a well-distributed trade-off solution without using any relative preference information. Once a well-distributed set of trade-off options has been identified, afterwards, higher-level information is used to select one of the trade-off options in Step 2 (horizontally, towards the right) [3].
For a problem with a single objective, Step 1 will result in an exact one global optimal solution, preventing it from moving on to Step 2. Both steps are required in the event of a single-objective optimization with several global optima to locate all or most of the global optima initially. And then to select one from them using the problem’s higher-level knowledge [3].
Mathematical programming and Evolutionary Algorithms (EA) are two main categories of a postriori optimization methods. It is also called the ideal multi-objective optimization techniques, which are depicted schematically in Figure 12.
Figure 12. Schematic of a two-step multi-objective optimization procedure.
These techniques are effective for black-box optimization as they don’t require knowledge of the underlying physics. They can also handle discontinuous, high-dimensional, and multi-modal problems, but they do not guarantee precise or satisfactory solutions [9].
Among these, mathematical computations methods, and the evolutionary approach (EA) uses the principles of nature’s evolution to guide its search for the best answer, four different evolutionary algorithms, i.e., genetic algorithms (GAs), evolution strategy (ES), evolutionary programming (EP) and genetic programming (GP) which are considered a population based, or an ideal multi-objective optimization procedure, in the following section the most famous methods will be outlined [9].
Multi‑objective Evolutionary Algorithms (MOEAs)
Figure 13 demonstrates that multi-objective evolutionary algorithms can be classified into three main categories, Dominance-based, indicator-based, and decomposition-based algorithms are the three types of evolution-based algorithms.
Figure 13. Classification of multi-objective evolutionary algorithms.
Dominance-based algorithms:Fitness is ascribed to solutions based on the Pareto dominance principle. Examples of dominance-based algorithms are Multi-Objective Optimization Algorithm (MOGA), Strength Pareto Evolutionary Algorithm (SPEA), Pareto archived Evolutionary Algorithm (PAES), and Non-Dominated Sorting Genetic Algorithm II (NSGA II) [9]. Dominance-based is also called Pareto-based based where the MOEAs employ a two-tiered ranking system. The first ranking is governed by the relationship of Pareto dominance, while the ranking at the second level is predicated on how each point contributes to diversity [34].
In MOEAs, all trade-off solutions are treated equally. If objective importance is known, the problem can be simplified using weighted sum functions. In priori methods, preferences are provided before solving, allowing conversion to a single-objective problem. In a posteriori method, preferences are used after generating a well-distributed Pareto front, from which the decision-maker selects the preferred solution—this is known as an ideal preference approach [10].
Numerous preference-based techniques have been developed. The initial attempt was by Fonseca and Fleming [33], who proposed ranking the population members based on both Pareto dominance and the decision maker’s preferences. A fuzzy approach was also introduced, where the person who makes decisions specifies preferences using preference points. Branke and Deb incorporated preference information into NSGA-II by modifying the dominance definition and applying a biased crowding distance based on weights [37] proposed a multi-objective evolutionary algorithm (MOEA) that partitions the objective space into levels, integrates prior preferences using meaningful parameters, and automatically constructs scalar objectives without requiring weight selection.
Indicator-based algorithms (IBEA):in which the ranking or selection of individuals is dependent on the value of the indicator measure, some of these (IBEA) algorithms, S-Metric Selection Evolutionary Multi-Objective Algorithm (SMS-EMOA), Portfolio Selection Multi-Objective Evolutionary Algorithm (POSEA) and Hypervolume Estimation Algorithm (HypE) [9].
These types of MOEAs are equipped with quality indicators to direct the search methodology. Hypervolume and generational distances are good examples of these metrics using an arbitrary indicator to compare two pairs of possible solutions. This approach is called the indicator-based evolutionary algorithm (IBEA), which was developed by Zitzler and Künzli. Another approach, introduced by Brockhoff and Zitzler, focuses oZn objective reduction techniques and hypervolume-based methods [38]. This approach was further advanced by Bader and Zitzler, who proposed a fast hypervolume-based MOEA for addressing many-objective optimization problems. It has since become a widely adopted method for resolving problems with several objectives. Subsequently, [35] explored the robustness of hypervolume-based multi-objective search methods. In their work, they introduced three novel strategies for addressing robustness within the field of evolutionary computing: modifying the objective functions, incorporating additional objectives, and imposing robustness constraints. These strategies were then integrated into a multi-objective hypervolume-based search framework [35].
Decomposition-based algorithms: utilize scalarization techniques to decompose the problem into many smaller subproblems, which are subsequently solved cooperatively. Among these methods are the following: MOEA/D based on decomposition (MOEA/D) [20], VEGA (Vector Evaluating Genetic Algorithm) [39], Non-Dominated Sorting Genetic Algorithm III (NSGA-III) [40], MOEA/D based on dynamic resource allocation (MOEA/D-DRA) [41], and MOEA/DD based on dominance and decomposition (MOEA/DD) [28].
MOEA/D is a multi-objective evolutionary algorithm framework that uses conventional aggregation approaches to decompose MOP into scalar sub-objective optimization problems. These subproblems can be linearly or nonlinearly weighted, and their neighboring relations are established based on distances between their aggregation weighting vectors. Each subproblem keeps one solution in its memory, and the algorithm generates a new solution if it’s better than the old one. Each individual neighboring subproblem will update its current solutions if it receives a solution better than the old one. A key advantage of MOEA/D is that local search can be naturally applied to each subproblem, as each one involves optimizing a scalar objective function [20].
3.3. Interactive Optimization Methods (IMO)
The decision-maker is given access to intermediate search results in an interactive method, which helps them comprehend the issue and gives more preference data to direct the search. User input on preferences is requested at several points throughout the algorithm’s execution in order to enhance the objective functions, constraints, and their priority.
The goal of interactive multi-objective optimization (IMO) is to determine a decision maker’s most favored solution while considering a series of progressive preferences. The decision maker can modify their choices and narrow their search space exploration to only areas they are interested in. Over the last few decades, two distinct approaches—the evolutionary multi-objective optimization (EMO) and multiple criteria decision making (MCDM)—have progressively come to share an interest in IMO. While IMO methods rooted in EMO often use evolutionary algorithms to generate a representative set of solutions in the decision maker’s preferred region, IMO methods developed by the MCDM community typically use mathematical programming methodology. One preferred. Pareto’s solution [42][43].
Two essential components of interactive multi-objective optimization are the DM and machine (algorithm). To demonstrate how the DM and the machine communicate when employing IMO approaches, a DM-Machine interaction system is displayed in Figure 14.
Figure 14. DM-machine interaction system.
The machine is essentially an algorithm that combines a search engine (optimization algorithm) with a preference model. The DM is a human DM who wants to determine his or her most preferred solution [42].
The figure above depicts the entire interaction process. The decision-maker expresses their preferences based on their comprehension of the issue and the algorithm-generated answers. Then, acting as a conduit between the algorithm and the decision-maker, it builds a preference model utilizing the input supplied [42].
The findings are shared with the decision-maker, enabling them to refine their preferences. Through interaction with the algorithm, the decision-maker gains insights and adjusts their preferences to determine the most favored solution [42]. The development of Interactive Multi-Objective (IMO) techniques consists of three main components: search engine, preference model, and preference information. The decision maker (DM) provides various forms of preference information, each affecting their cognitive load differently. The preference model defines how the machine utilizes the DM’s preferences, without the DM needing to be aware of it. The algorithm that the search engine uses determines the quality of the results [42].
Any interactive optimization methods will be built on four fundamental design elements: Search engine, preference model, preference information, and interaction pattern come in order of importance; one of two interaction patterns is utilized either interaction after run (IAR) or interaction during run (IDR).
The IMO methodologies have mostly embraced both IAR and IDR patterns. As seen in Figure 15(a) and Figure 15(b), an IMO technique that follows the IAR pattern can produce one or a set of (approximate) Pareto optimum solutions at each iteration since it runs the search engine through from start to finish between two neighboring interactions. The DM can contribute preferences such as reference points, weights, tradeoffs, and the categorization of objectives. If just one solution is developed and presented to them, DM is presented with more than one solution.
The solutions obtained in the first three iterations of IMO methods are demonstrated. The curve in each sub-figure represents the Pareto front. (a) and (b) show a single solution (z) and a set of solutions (F) obtained by methods adopting the IAR pattern, respectively. (c) illustrates how a population (P) changes over time in accordance with the decision maker’s (DM’s) preferences using methods that follow the IDR pattern [14].
In addition to providing tradeoffs or a categorization of objectives on the most desirable option, decision makers may also give reference points or weights and compare these solutions. Classical interactive MCDM techniques use the IAR pattern to find one or more Pareto optimum solutions for each iteration. Additionally, it is utilized in certain interactive MOEAs, such as those that rely on reference point data. Section III has specifics on various IMO techniques [14].
As seen in Figure 15(c), IMO approaches that follow the IDR pattern allow the DM to provide preferences at regular intervals throughout the search engine run in order to direct the search towards the DM’s area of interest (ROI). In most cases, the population does not approach the Pareto front until much later in the optimization process. According to [6][11], the DM is more active in the whole optimization-cum-decision making process in this scenario since they have more opportunities to offer fresh information. Thus, the IDR pattern’s IMO procedure is more DM-focused. It should be mentioned that approaches using the IAR pattern are better suited for preferences like tradeoffs and objective categorization, since it is more relevant to take these tradeoffs into account.
Figure 15. Dm’s preferences for methods adopting the IDR or IAR pattern [19].
Preference Information can be categorized into three different ways: expectation that DM wants to achieve, the comparison of objective functions and the comparison of solutions, which requires the DM to make comparisons when expressing preferences. It is possible to compare objective functions using weights, trade-offs, objective categorization, etc. Weights are frequently employed to represent the relative significance of goals, and finally, a tradeoff is when one solution is given up in order to improve another at a feasible solution [44][45].
Reference Model widely employs one of three types of preference models: choice rules, dominance relations, and value functions (also known as utility functions). A value function (VF) is a scalar function that assesses solutions quantitatively for all objectives. The DM either explicitly specifies its parameters or indirectly determines them depending on the DM’s preferences. The DM’s preferences are expressed as a relationship between two solutions, which is known as a dominant relation.
In the selection operator of interactive MOEAs, it frequently takes the role of the relationship of Pareto dominance [42]. The following table shows a summary of the preference types.
Table 1 illustrates the advantages and disadvantages of search engines, preference model, and preference information.
Table 1. Common kinds of information about preferences and their pros and cons [14].
Category
Preference Information
Features
Advantages and Disadvantages
Expectation
Reference point
A reference point consists of k continuous valued aspiration levels representing desirable objective values (quantitative).
The reference point could either be accessible or not, and the DM has the discretion to define it. Calculating the objective ranges is frequently necessary, and additional computational effort or prior knowledge may be required
Comparison of objective functions
Weights
The purpose of weights is to show how important one objective is in relation to others. They can be derived from the decision-maker’s (DM’s) pairwise comparisons of objectives or explicitly provided by the DM as k scalar values.
There is a widespread misunderstanding that weights will indicate how important each goal is in relation to the others. However, it is unclear what these notions actually represent. Additionally, employing weights to control the solution process isn’t always easy for the DM [
46
].
Tradeoffs
In general, taking one objective as the reference objective, the DM needs to give the amount of increment of each of the remaining k-1 objectives to compensate one unit decrement of the reference objective (quantitative).
Although tradeoffs can facilitate the quest for a more ideal solution, they also put a heavy cognitive burden on the DM because they must decide how much compromise is acceptable between objectives.
Classifying of objectives
The DM is tasked with categorizing objectives based on desirable changes and specifying aspiration levels or upper bounds for some objectives.
Establishing reference points is strongly related to classifying objectives. The decision-maker has more control over the process of finding a solution when objectives are categorized and the degree of relaxation permitted for those that can be compromised is specified. But it’s crucial to remember that the decision-maker’s burden will rise as a result of these new responsibilities.
Comparison of solutions
Pairwise comparison of solutions
determining whether solution is better than the other, whether they are equal, indifferent, or neither (qualitative).
Relatively less mental work is required of the decision-maker while comparing solutions. However, as the number of solutions increases, their duties will probably also expand.
Classification of solutions
Dividing a set of solutions into different categories where solutions in each category incomparable or indifferent (qualitative).
Selecting the most referred solution
Selecting the most preferred solution among group of solutions (qualitative).
Models of preference have been widely utilized in the literature, including value functions (or utility functions), dominance relations, and decision rules [47]. Decision rules typically consist of two parts: the premise, which outlines the criteria that objectives and/or solutions must satisfy, and the decision section, which establishes the relationships between solutions or assigns them a score [42].Many methods model DM’s underlying value function (VF) dynamically based on DM’s preferences. Three types of popular VFs are explained; a) A weighted metric measures the distance between the objective vector and a certain point, b) Wierzbicki introduced a successful scalarizing function (ASF) as part of the reference point technique, According to Wierzbicki, it is a modified value function (VF) that communicates both the usefulness of meeting aspirations and the disutility of failing to do so [48]. ASFs have been created in various forms [49][50], c) The DM is symbolized by only one compatible additive value function [51]. The term “compatible” refers to the IMO approach’s ability to create a preference model that ranks solutions similarly to the DM method [52][53] examines all compatible additive VFs.But for the dominance relations, dominance relation indicates the DM’s choice between two solutions: one is chosen over the other, or both are indifferent or incomparable. The binary relation between two solutions, x and y, can be expressed as xDy (x dominates y), yDx (y dominates x), or xDNy (indifferent). Dominance relations sometimes combine Pareto and DM preferences, allowing for comparison of non-dominated solutions [13][42][54].Decision-makers usually apply “IF-THEN” principles according to their personal preferences. Decision rules can explain the relationships between solutions or assign solution scores to help choose the best options if certain criteria are satisfied by the objectives and/or solutions. Because of their inherent error, preference models in decision rules are more general and simpler for DMs to understand. The DM’s qualitative preferences may be transformed into quantitative data on goals or solutions using fuzzy rules, a sort of decision rule [55].In hybrid preference model some IMO approaches use a mixed preference model. In [56], the r-dominance relation is defined using the weighted Euclidean distance. A solution x is said to r-dominate a solution y if they meet any of the following two conditions: 1) x Pareto dominates y; 2) x and y are non-dominated; x is closer to the reference point than y in terms of weighted Euclidean distance; and the absolute value of their distance difference exceeds a threshold. [57][58], after getting the strengths of solutions using the fuzzy inference system, a strength superior relation is established to define a fitness function.
IMO approaches utilize search engines classified into mathematical programming (MP) techniques and non-MP strategies. techniques for optimization, including linear, nonlinear, and multi-objective programming, are specifically designed for software systems. In the MCDM community, IMO approaches frequently achieve Pareto-optimal solutions [42].
3.4. Non-Preference-Based Methods
In contrast to preference-based procedures, population-based approaches do not require predefined information before searching or solving problems; instead, for every simulation run, a collection of solutions is produced, and the best solutions are selected to form the Pareto frontier set of solutions through additional sorting. In recent years, a variety of non-classical, unconventional, and stochastic search and optimization algorithms have been introduced, transforming the field of search and optimization [3].
3.5. Hybridization Techniques
In Figure 4, Hybrid techniques, which, although not fully studied yet, may comprise various Evolutionary Multi-objectives Optimization algorithms or a combination of MCDM (multi-criteria decision making) and EMO; its future uses might supplant existing technologies that depend on goal-oriented approaches. Speed-constrained Multi-objective Particle Swarm Optimization (SMPSO) is one of the potential high-performance algorithms, since the single objective version of the method (PSO) outperformed the EA-based alternatives [54][59]. Other approaches like the Parallel Re-Combinative Simulated Annealing technique [60], address the issue of genetic drift by integrating the principle of the cooling sequence from simulated annealing [61], Boltzmann tournament selection [62], and standard genetic operators. One of the well-known hybridization methods is the Local Search Memetic Genetic Algorithms (GAs) employ a global search strategy; however, they often require a relatively long time to converge to the global optimum. To address this, a population-based GA can be combined with an individual learning procedure to improve the fine-tuning of global search.
When a genetic algorithm is integrated with a local search procedure, it forms a hybrid genetic algorithm (HGA). The basic steps of an HGA are as follows [63]:
1) Specify the objective or fitness function, and configure the genetic algorithm parameters, including population size, parent-to-offspring ratio, selection strategy, crossover count and mutation rate.
2) Create the first population at random as the current parent population.
3) Evaluate the objective function for each individual (chromosome or solution) in the initial population.
4) Produce the offspring population by applying GA operations like crossover, mutation, and selection.
5) Determine the objective function values for all individuals in the offspring population.
6) Perform a local search on each offspring, evaluating fitness of each new location, and replace the offspring if a better local option is available.
7) Select the individuals that will form the next generation; this process is known as replacement in that individuals from the current parent population are “replaced” by a new population formed from individuals selected from the offspring and/or parent generations.
8) If the criterion for stopping is met, the process terminates; otherwise, return to Step 4.
Among these learning searching techniques (LS) are the Nelder-Mead Simplex method and the three-dimensional local search. The Best-Offspring Hybrid Genetic Algorithm is one of the developed algorithms that is built on earlier principles (BOHGAS) [64]. The objective of this algorithm is to lower the overall LS expenses. It has been observed that the LS may be run repeatedly on the same “valley” (to find the lowest) or “mountain” (to find the maximum) [65]. Therefore, after local search, it is likely that several chromosomes within a generation become clustered closely together, positioned on the same or closer to the peak or at the same or closer to the valley. This may make it harder for the GA to maintain diversity in its population, an important consideration in avoiding converging to a local optimum [66].
3.6. Advantages and Disadvantages of a Priori, a Posteriori, and Interactive Preference Approaches
When the DM is expected to offer preference, information is a crucial component of MCDM. To achieve this, there are three options:
Prior to the search (a priori approaches).Posteriori.Interactive preferences.
Its widespread use is due to the fact that any optimization procedure that makes use of this a priori knowledge becomes easy. The primary challenge (and disadvantage of the method) lies in locating this first global preference data [42].
Interactive approaches have been normally favored by researchers [67] for several reasons:
The entire set of components of a situation, besides the context in which it is embedded, can affect perception.Individual preference functions or value structures cannot be expressed analytically, although it is assumed that the DM subscribes to a set of beliefs.Value structures change over time, and preferences of the DM can change over time as well.Aspirations or desires change as a result of learning and experience.The DM normally looks at trade-offs satisfying a certain set of criteria, rather than at optimizing all the objectives one after the other.
Interactive techniques also present several challenges, particularly concerning the preference data the decision-maker (DM) must provide while conducting the search. For instance, the DM may be asked to evaluate a set of options for each goal, assign weights, or adjust ambition levels. These tasks are often complex, and DMs frequently find it difficult to offer input that effectively guides searching for the best compromise solution.
In the field of OR, posteriori methods are also often used [68][69]. These methods’ primary benefit is that, because they are predicated on the idea that “more is better,” no utility function is needed for the analysis [70]. The primary drawbacks of posteriori methods are:
The algorithms used with these approaches are normally very complex and tend to be difficult for the DM to understand.Many real-world problems are too large and complex to be solved using this sort of approach.The number of solutions in the Pareto optimal set is typically too large for the decision maker to analyze effectively.
Combining two or more of these techniques is also a possibility. An approach that may be developed is to ask the DM for some pre-search information and then ask them to modify their choices while the search is underway. Comparing this to using the two methods separately, it might be more effective.
3.7. Classification Strategies: Static and Dynamic Strategies
Fei Wu etal. (2023) developed a dynamic optimization algorithm to face the following problems [70]:
1) How to deal with diversity, keeping the population convergence and diversity balanced?
2) What is the best way to design a prediction strategy that is both robust and efficient?
3) From the strategy, the classification of decision variables is not clear.
Mohammad Reza Sharif etal. (2021) introduced a multi-objective moth swarm algorithm featuring a novel definition of pathfinder moths and moonlight, aimed at improving synchronization and preserving a well-distributed set of non-dominated solutions. Furthermore, the crowding-distance method was used to choose the most efficient solutions within the population. The efficiency of the suggested MOMSA was evaluated using a series of multi-objective benchmark problems ranging from 7 to 30 dimensions [70].
They were compared with the results. Against three well-known meta-heuristics, including the decomposition-based multi-objective evolutionary algorithm (MOEA/D) and the Pareto envelope-based selection algorithm II (PESA-II), and multi-objective ant lion optimizer (MOALO). To facilitate comparison, four measures were used: generational distance (GD), spread (Δ), spacing (S), and maximum spread (MS). Sandra C. Cerda-Flores etal. (2022) introduced a similar article on potential multi-objective methods [70].
3.8. Classification of Meta-Heuristic Algorithms According to Their Nature: Swarm-Based, Evolutionary-Based, Physics-Based, and Human-Based
Meta-heuristic algorithms are analyzed and compared across five key aspects, followed by a classification of the algorithms based on these criteria and These classifications are according to:
The type of algorithms (swarm-based, evolutionary-based, physics-based and human-based). Nature-inspired vs. non-nature-inspired. The inspiration’s origin. Population-based vs. single solution-based. Based on the country of origin.
Today, algorithms are generally classified into four main categories: physics/chemistry-based, bio-inspired (excluding swarm intelligence), swarm intelligence (SI)-based, and a miscellaneous group. The latter includes algorithms that are difficult to categorize under the first three groups, as they incorporate diverse characteristics from various domains such as social behavior and emotional processes [3].

4. Conclusions
Multi-objective optimization formulation can be mainly categorized into three families, the first is prioritization, in which optimization starts with the highest priority objective, and the consequence objective. The process starts with the most important one, lexicographic is a good procedure for this formulation, the second family is the preference-based or the weighing formulations, which in turn are divided into, priori, postriori, or interactive approaches, depend on where the decision maker puts his input, and finally the non-preference methods in which tradeoff solutions are generated without any decision-making inputs. Still, multi-objective methods lack a methodology for dealing with multi-objective Pareto fronts.Each family involves several different methods; each one has its own search technique, preference conditions, and attributes. The multi-objective optimization procedure can also be a hybrid of two or more different methods/formulations in order to fix a drawback of individual methods. By merging different techniques, one can create a hybrid that has multiple advantages that cannot be reached when using a single optimization method.The ability of an optimization method depends on many factors, like searching techniques, decision makers’ interaction, the point at which the decision maker puts his references, type of references, a priori, postriori, interactive, or no-preference based, type and complexity, and number of objectives and constraints in the optimization problems.Clustering of solutions is still a drawback of all methods utilizing metaheuristics; this should be considered in future research.
