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 http://www.columbia.edu/~cs2035/courses/ieor3608.F05/david-bigM.pdf WebbTo use the simplex algorithm we need our LP in standard form maximise f = c ¯ T x ¯ subject to A x ¯ = b ¯ and x ¯ ≥ 0. The reason for introducing slack variables is solely to convert the constraints A x ¯ ≤ b ¯ to the standard form A x ¯ = b ¯ so that we can apply the simplex algorithm.

"WebbThe simplex algorithm is probably the simplest way to minimize a fairly well-behaved function. It requires only function evaluations and is a good choice for simple minimization problems. However, because it does not use any gradient evaluations, it may take longer to find the minimum. " - Simplex method sums
