WebTwo-Phase method calculator - Solve the Linear programming problem using Two-Phase method, step-by-step online WebIn 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 the Phase I LP, the objective function is to minimize the sum of all artificial variables. At the completion of Phase I, we reintroduce the
