WebbAdvantages of Revised Simplex Method • For LPP involving large number of variables, the number of constraints and the amount of computations is very much reduced. • Less amount of new information needs to be stored in the memory of the computer from one iteration to other. • There is less accumulation of round-off errors, since the revised … WebbThe solution is the two-phase simplex method. In this method, we: 1.Solve an auxiliary problem, which has a built-in starting point, to determine if the original linear program is feasible. If we succeed, we nd a basic feasible solution to the orignal LP. 2.From that basic feasible solution, solve the linear program the way we’ve done it before.
WebbIt enabled solutions of linear programming problems that were beyond the capabilities of the simplex method. In contrast to the simplex method, it reaches a best solution by traversing the interior of the feasible region. The method can be generalized to convex programming based on a self-concordant barrier function used to encode the convex set.
