WebbThe Simplex method is an approach for determining the optimal value of a linear program by hand. The method produces an optimal solution to satisfy the given constraints and produce a maximum zeta value. To use the Simplex method, a given linear programming model needs to be in standard form, where slack variables can then be introduced. 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 ...
