WebbLet 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. Hence, if xˆ1 > 0, then c1 =6 −1 2 yˆ1 − ˆy2 =0; if xˆ3 > 0, then c3 =13 − ˆy1 −4yˆ2 =0. WebbThe Simplex algorithm is an algebraic procedure to solve LP problems based on geometric concepts that must be translated into algebraic language to allow solving systems of equations. 1 st transform all inequalities into equalities by introducing one additional variable to each constraint (the slack variables: S1, S2, S3).
