AUTOPERTURB

Simplex: This indicates whether automatic perturbation is performed. If this is set to 1, the problem will be perturbed whenever the simplex method encounters an excessive number of degenerate pivot steps, thus preventing the Optimizer being hindered by degeneracies.

Integer

0	No perturbation performed.
1	Automatic perturbation is performed.
