![]() Just so, what is the difference between simplex and dual simplex method? This process can be broken down into 7 simple steps explained below. Furthermore, the simplex method is able to evaluate whether no solution actually exists.Īlso, what is the graphical method? Graphical method of linear programming is used to solve problems by finding the highest or lowest point of intersection between the objective function line and the feasible region on a graph. It examines the feasible set's adjacent vertices in sequence to ensure that, at every new vertex, the objective function increases or is unaffected. The simplex method is used to eradicate the issues in linear programming. Regarding this, why do we use simplex method? The graphical method is preferable when the problem has two variables and only two or three constraints (and when no computer is available). (4) Simplex method involves use of surplus, slack, and artificial variables but provides useful economic data as a by- product.
