XKTR_PARAM_BAR_SWITCHRULE

Indicates whether or not the barrier algorithms will allow switching from an optimality phase to a pure feasibility phase.

Integer

0	(auto) Let Knitro determine the switching procedure.
1	(never) Never switch to feasibility phase.
2	(level1) Allow switches to feasibility phase.
3	(level2) Use a more aggressive switching rule.

0

This option has no effect on the Active Set algorithm.
