Exercise 4.8 Consider the linear programming problem of minimizing CX subject

Exercise 4.8 Consider the linear programming problem of minimizing CX subject to Ax = b, x 2 >:0. Let x* be an optimal solution, assumed to exist, and let p* be an optimal solution to the dual. (a) Let x be an optimal solution to the primal, when c is replaced by some C. Show that (c-c)' (x-x*) :0. Let x* be an optimal solution, assumed to exist, and let p* be an optimal solution to the dual. (a) Let x be an optimal solution to the primal, when c is replaced by some C. Show that (c-c)' (x-x*)
