WebbThe simplex method is one of the popular solution methods that are used in solving the problems related to linear programming. The two variables and constraints are involved in this method. In this, basic variables are the solutions given for the constraint equation having non-zero variables. WebbThat is accomplished by a method due to C. E. Lemke [ ] which is ucually called the dual simplex method. We shall rst describe it as a mirror image of the simplex method and then we shall illustrate it on the example (1). Only then we shall note (without proof) that the dual simplex method is nothing but a disguised simplex method working on ...
