WebbA globally optimal solution is one where there are no other feasible solutions with better objective function values. What is the condition for Simplex optimality? Optimality … WebbThis proves optimality of both x and u. The value uTb is an upper bound for all primal objective values, so because cTx reaches that bound, x is optimal. Similarly, the value cTx is a lower bound for all dual objective values, so because uTb reaches that bound, u is optimal. The intuition behind complementary slackness is that the dual variable u phong when he tries straight line https://paintingbyjesse.com
