WebbThe Simplex method is an approach for determining the optimal value of a linear program by hand. The method produces an optimal solution to satisfy the given constraints and produce a maximum zeta value. To use the Simplex method, a given linear programming model needs to be in standard form, where slack variables can then be introduced. WebbThe simplex algorithm is an iterative procedure for solving LP problems. It consists of: (i) Having a trial basic feasible solution to constraints equation, ADVERTISEMENTS: (ii) …
