Webb9 apr. 2024 · In other words, the simplex algorithm is an iterative procedure carried systematically to determine the optimal solution from the set of feasible solutions. Firstly, to apply the simplex method, appropriate variables are introduced in the linear programming problem, and the primary or the decision variables are equated to zero. WebbThe Simplex method is an iterative process which approaches an optimum solution in such a way that an objective function of maximization or minimization is fully reached. Each iteration in this process shortens the distance (mathematically and graphically) from the objective function. A5:
