WebIn linear programming, reduced cost, or opportunity cost, is the amount by which an objective function coefficient would have to improve (so increase for maximization problem, decrease for minimization problem) before it would be possible for a corresponding variable to assume a positive value in the optimal solution. It is the cost for increasing a variable … Web11 apr. 2024 · The if then contraints can be written equivalently as. If b = 0, then a < 1; and. If b = 1, then a ≥ 1. Introduce a large number M and add the following constraints: b ( M + 1) − M ≤ a < b ( M + 1) + 1. EDIT: I assumed that b is binary. If a is bounded a ∈ [ L, U), we can write the constraints as: b ( − L + 1) + L ≤ a < b ( U − 1 ...
