WebbTwo-Phase Simplex method This method differs from Simplex method that first it is necessary to accomplish an auxiliary problem that has to minimize the sum of artificial variables. Once this first problem is resolved and reorganizing the final board, we start with the second phase, that consists in making a normal Simplex. 1st Phase WebbIn the second step, Phase II, the simplex algorithm is applied using the basic feasible solution found in Phase I as a starting point. The possible results from Phase II are either an optimum basic feasible solution or an infinite edge on which the objective function is unbounded above.

Webb4 Advanced Simplex Procedures 4.1 The Two-Phase Simplex Method The LP we solved in the previous lecture allowed us to ﬁnd an initial BFS very easily. In cases where such an obvious candidate for an initial BFS does not exist, we use an additional phase I to ﬁnd a BFS. In phase II we then proceed as in the previous lecture. Consider the LP to WebbSo the Simplex Method as we studied it initially is really only “Phase 2” of the full 2-phase Simplex Method! It’s just that we initially discussed only the case where the starting dictionary was feasible, so we could skip Phase 1. Example of an infeasible LP.
