Webb(1) with the Simplex method in two phases. In phase I we solve Eq. (15); if the problem is infeasible it is detected in this phase, otherwise we obtain a basic feasible solution of Eq. (1) that can be used in phase II to solve the problem. Phase II either yields an optimal basic solution, or detects that the problem is (feasible and) unbounded. 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.

"WebbThe concept of multiple optimal solutions is associated with the linear programming problems. The multiple optimal solutions will arise in a linear program with more than one set of basic solutions that can minimize or maximize the required objective function. Sometimes, the multiple optimal solutions are called the alternative basic solution. " - Simplex method alternative optimal solution
