WebbIn the two-phase simplex method, we add artificial variables to the same constraints as we did in big M method. Then we find a bfs to the original LP by solving the Phase I LP. In … 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

WebbThe procedure for starting "ill-behaved" LPs with (=) and (≥) constraints is to use artificial variables that play the role of slacks at the first iteration, and then dispose of them legitimately at a later iteration. Two closely related methods are introduced here: the M-method and the two-phase method. 1. M-Method.
