"the solution without the constraint is different from the solution with the constraint." This isn't quite right: consider max x 1 subject to ⩽ x 1 + x 2 ⩽ 1, ⩽ x 1 ⩽ 1 and ⩾ x 1, x 2 ⩾ 0. The constraint ⩽ x 1 ⩽ 1 is active at the optimal solution ( 1, 0), but removing it does not change the optimal solution. how do you say test in italian
