Mixed-integer linear programming (MILP) involves problems in which only some of the variables, , are constrained to be integers, while other variables are allowed to be non-integers. Zero-one linear programming (or binary integer programming) involves problems in which the variables are restricted to be either 0 or 1. Any bounded integer variable can be expressed as a combination of binary variables. For example, given an integer variable, , the variable can be exp… WebAnswer to: There are 3 types of Integer Programming Models: 0-1, Total, and Mixed.
