If a customer reports slow performance on a linear program, degeneracy is a likely cause. To verify this, check the CPLEX iteration log and look for long sequences of iterations where the objective value remains unchanged. Also, look for messages that indicate CPLEX has
WebbThis subset is used in all further iterations of the simplex method until the pivot pool either becomes empty or grows too old. This allows the algorithm to choose entering variables quickly (by one of rules (2), (3), or (4), above, for example), but only considering a tuned subset of the entire set of variables. 3 Cycling & Bland’s Rule
