Question

Quizplus · Accepted Answer

The slack values in the Answer Report can refer to either slack or surplus values depending on whether the inequality is a less than or a greater than constraint. For less than constraints, the slack value indicates the amount by which the left-hand side of the constraint can be increased before the constraint becomes binding. For greater than constraints, the slack value indicates the amount by which the left-hand side of the constraint can be decreased before the constraint becomes binding. In both cases, the same numerical value can be either a slack or a surplus, depending on the direction of the inequality.
