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. Webb23 juni 2024 · The Big M Method Procedure If an LP has any > or = constraints, the Big M method or the two-phase simplex method may be used to solve the problem.
