Inputs Simply enter your linear programming problem as follows 1) Select if the problem is maximization or minimization 2) Enter the cost vector in the space provided, ie in boxes labeled with the Ci. PHPSimplex is an online tool to solve linear programming problems. It can be used for free. The method employed by this function is the two phase tableau simplex method. If there are >= or equality constraints an initial feasible solution is not easy to find. To find a feasible solution an artificial variable is introduced into each >= or equality constraint and an auxiliary objective function is defined as the sum of these artificial What is the idea of the simplex method?
