How to solve degeneracy in simplex method

WebThe Big-M-Method is an alternative method of solving a linear programming problem involving artificial variables. To solve a L.P.P by simplex method, we have to start with the initial basic feasible solution and construct the initial simplex table. In the previous problems we see that the slack variables readily provided the initial basic ...

WebAgain, while solving LPP the situation may arise in which there is a tie between two or more basic variables for leaving the basis i.e minimum ratio to identify the basic variable to leave the basis is not unique or values of one or more basic variables in the solution values column (x B) become equal to zero. This causes the problem of degeneracy.
