A mixed-integer programming solver can be used to effectively optimize the objective function while taking the restrictions into account. The best solution found for this issue indicates that, while sites C and D shouldn't be exploited, sites ... 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.
