If the original problem is feasible, we will be able to find a BFS where y1 =y2 =0. This automatically gives us an initial BFS for the original problem. In summary, the two-phase simplex method proceeds as ...
Webb4. Phase II: solve the original problem, starting from the BFS found in phase I. While the original objective is not needed for phase I, it is useful to carry it along as an extra row in … WebbTwo-phase method: an algorithm that solves (P ) in two phases, where • in Phase 1, we solve an auxiliary LP problem to either get a feasible basis or conclude that (P ) is infeasible. • in Phase 2, we solve (P ) starting from the feasible basis found in Phase 1. Remark: from Phase 1, we see that finding feasible basis is as easy as solving LP.
