Consider our primal problems. It’d be interesting to know how much more I could get, had my knapsack been larger or my body stronger. This looks like a difficult question in the primal program, but it’s very obvious in the dual program. WebAn economic interpretation of the dual variables and dual problem further exploits the concepts in duality theory. These concepts are then used to derive two important simplex … fox news 21 election targeting
