WebApr 20, 2024 · We can denote the binary variables as food_chosen and instantiate them as Integer with lower and upper bounds of 0 and 1. food_chosen = LpVariable.dicts ("Chosen",food_items,0,1,cat='Integer') Then we write a special code to link the usual food_vars and the binary food_chosen and add this constraint to the problem. for f in … WebJan 28, 2024 · First, note that the feasible region associated with your constraint is non-convex. Thus it is not possible to formulate this constraint using linear programming alone. Typically, constraints like these are formulated in mixed integer programming by using 0-1 binary variables (the integer aspect of the formulation) to turn constraints on and off.
