Mixed IP formulation requires that:
A) all decision variables must be integer
B) the optimal objective function value must be integer
C) some decision variables must be integer
D) some decision variables and the optimal value of the objective function must be integer

Question

Quizplus · Accepted Answer

In mixed integer programming, some decision variables are restricted to integer values, while others can take continuous values. Mixed IP formulation is a type of mixed integer programming where some decision variables must be integer. The optimal objective function value, however, may or may not be integer. Therefore, neither A, B nor D is correct.
