Duality in Linear Programming 4
132 Duality in Linear Programming 4.1 The situation is much the same for the nonbasic variables x2,x4, and x5, with corresponding reduced costs: c2 =14 −11(2)−1 2 (2) =−9, c4 =0 −11(1)−1 2 (0) =−11, c5 =0 −11(0)−1 2 (1) =−1 2. The reduced costs for all nonbasic variables are negative. The interpretation is that, for the values ...
