Simplex method ppt

WebbThe solution is the two-phase simplex method. In this method, we: 1.Solve an auxiliary problem, which has a built-in starting point, to determine if the original linear program is feasible. If we succeed, we nd a basic feasible solution to the orignal LP. 2.From that basic feasible solution, solve the linear program the way we’ve done it before. 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 …
