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. http://avitevet.com/algorithms/when-to-use-it-simplex-method/
