WebbStep 4 - Choose the method for solving the linear programming problem. Multiple techniques can be used to solve a linear programming problem. These techniques include: Simplex method. Solving the problem using R. Solving the problem by employing the graphical method. Solving the problem using an open solver. WebbSo we apply the above outlined procedure to resolve degeneracy (Tie). First arrange the column X 1, X 2, S 1, and S 2 in such a way that the initial identity (basis) matrix appears first. Thus the initial simplex table becomes. Which occurs for the second row. Hence S 2 must leave the basic, and the key element is 2 as shown above. WebbIt should be quite clear that this procedure of pricing out a new activity is not restricted to knowing in advance whether the activity will be promising or not. The pricing-out mechanism, ...
