WebbThe original simplex algorithm starts with an arbitrary basic feasible solution, and then changes the basis in order to decrease the minimization target and find an optimal solution. Usually, the target indeed decreases in every step, and thus after a bounded number of steps an optimal solution is found. WebbUsing simplex method make iterations till an optimal basic feasible solution for it is obtained. It may be noted that the new objective function W is always of minimization type regardless of whether the given (original ) L.P.P. is of maximization or minimization type. Let us take the following example. Example 1 (Two phase simplex Method):
