WebbThe basic method for solving linear programming problems is called the simplex method, which has several variants. Another popular approach is the interior-point method. WebbBegin the simplex algorithm simplex with the current basis B and current ( x, y). If the algorithm terminates before an artificial variable is eliminated: If the cost is zero, STOP. The problem is feasible, but extra steps need to be taken to drive the remaining artificial variables out of the basis. See Section 3.5 for details.

WebbNotes. This section describes the available solvers that can be selected by the ‘method’ parameter. ‘highs-ds’ and ‘highs-ipm’ are interfaces to the HiGHS simplex and interior-point method solvers , respectively. ‘highs’ (default) chooses between the two automatically. These are the fastest linear programming solvers in SciPy, especially for large, sparse … WebbTwo-Phase Simplex method. This method differs from Simplex method that first it is necessary to accomplish an auxiliary problem that has to minimize the sum of artificial variables. Once this first problem is resolved and reorganizing the final board, we start with the second phase, that consists in making a normal Simplex. 1st Phase
