WebThe primal simplex method is an active-set method. Given a nonsingular Band values of x N satisfying ‘ N x N u N, the current active set de nes a vertex of the form B N I x B x N = b x N (nactive constraints and nvariables). Primal simplex begins by solving Bx B = b Nx N and taking x B to be new values for the basic variables. From (1), this ... WebThis is an important result since it implies that the dual may be solved instead of the primal whenever there are computational advantages. Let us further emphasize the implications of solving these problems by the simplex method. The opti-mality conditions of the simplex method require that the reduced costs of basic variables be zero.
