Question

Quizplus · Accepted Answer

The range of feasibility measures the right-hand-side values for which the dual prices (or shadow prices) will not change. This range indicates how much you can increase or decrease a constraint's right-hand side before the shadow price becomes invalid, not the objective function value or the decision variables directly.
