Description

Decides whether to perturb problems.

Setting this parameter to 1 (one) causes all problems to be automatically perturbed as optimization begins. A setting of 0 (zero) allows CPLEX to decide dynamically, during solution, whether progress is slow enough to merit a perturbation. The situations in which a setting of 1 (one) helps are rare and restricted to problems that exhibit extreme degeneracy.
