WebbThe Simplex Method is the name given to the solution algorithm for solving LP problems developed by George B. Dantzig in 1947. It is iterative procedure having fixed computational rules that leads to a solution to the problem in a finite number of steps. By using this one is capable of solving large LP problems efficiently. 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.
