Simplex method sums
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 … WebbFind the solution to the minimization problem in Example 7.5. 1 by solving its dual using the simplex method. We rewrite our problem. Minimize Z = 12 x 1 + 16 x 2 Subject to: x 1 + 2 x 2 ≥ 40 x 1 + x 2 ≥ 30 x 1 ≥ 0; x 2 ≥ 0 Solution Maximize Z = 40 y 1 + 30 y 2 Subject to: y 1 + y 2 ≤ 12 2 y 1 + y 2 ≤ 16 y 1 ≥ 0; y 2 ≥ 0

Staring from … The simplex algorithm operates on linear programs in the canonical form maximize subject to and with the coefficients of the objective function, is the matrix transpose, and are the variables of the problem, is a p×n matrix, and . There is a straightforward process to convert any linear program into one in standard form, so using this form of li…
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.

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
