WebbLinear Programming 20: The simplex method - InfeasibilityAbstract: We show how to find a basic feasible solution (Phase I) using an auxiliary linear program,... WebbThe solution is the two-phase simplex method. In this method, we: 1.Solve an auxiliary problem, which has a built-in starting point, to determine if the original linear program is feasible. If we succeed, we nd a basic feasible solution to the orignal LP. 2.From that basic feasible solution, solve the linear program the way we’ve done it before.
