WebDegeneracy In the application of the feasibility condition of the simplex method, a tie for the mini-mum ratio may occur and can be broken arbitrarily. When this happens, at least one basic variable will be zero in the next iteration and the new solution is said to be degenerate. 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.
