Answer #1

Rounding __up___ non-integer solution values if all of the constraints are the greater-than-or-equal-to type is something which can ensure a feasible solution for a minimization integer linear programming problem. Whereas for a maximization integer linear programming problem, a feasible solution is ensured by rounding down non-integer solution values if all of the constraints are the greater-than-or-equal-to type.
