http://www.phpsimplex.com/en/simplex_method_theory.htm WebThe process of eliminating artificial variables is performed in phase-I of the solution and phase-II is used to get an optimal solution. Since the solution of LPP is computed in two phases, it is called as Two-Phase Simplex Method. Phase I – In this phase, the simplex method is applied to a specially constructed auxiliary linear
