WebJun 26, 2024 · However, the dual of the dual is the primal, so a simple work around might be to input the dual problem to linprog instead. That way, when linprog applies the "dual simplex algorithm", it will really be applying the simplex algorithm to the primal. The Lagrange multipliers (lambda) that it returns. should then give you the primal solution, as ... Webdecision variables of the firm’s allocation problem. Hence, in solving the dual (2) by the simplex method, we apparently have solved the primal (1) as well. As we will see later, this will always be the case since ‘‘the dual of the dual is the primal.’’ This is an important result since it implies that the dual may be solved instead
