Barrier Switch Rule

Type : Selection

Range : The settings listed below

Default : Automatic

This option indicates whether or not the barrier algorithms will allow switching from an optimality phase to a pure feasibility phase. Possible values are:

• Automatic

• Off

• Normal

• Aggressive

With setting ‘Off’ Knitro never switches to the feasibility phase. With setting ‘Normal’ Knitro allows switches to the feasibility phase and with setting ‘Aggressive’ a more aggressive switching rule is used.

This option has no effect on the Active Set and SQP algorithms.
