WebbThe simplex method is a systematic procedure for testing the vertices as possible solutions. Some simple optimization problems can be solved by drawing the constraints … 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.
