TITLE: Convexity Properties for a Function of Two Integer Variables
AUTHORS: Sara Nourazari, Hillel Kumin
KEYWORDS: Linear Integer Programming, Convexity
JOURNAL NAME: American Journal of Operations Research, Vol.11 No.6, October 13, 2021
ABSTRACT: Sufficient conditions are given for any local minimum of a function of two integer variables to be a global minimum. An example is given to show that a function of two integer variables need not be discrete convex for this condition to hold.
