Barrier Globalize

Type : Selection

Range : The settings listed below

Default : Filter

This option specifies the globalization strategy used by the interior-point algorithms. Possible values are:

• None

• Karush-Kuhn-Tucker

• Filter

With the setting ‘None’, Knitro does not apply a globalization strategy.

With the setting ‘Karush-Kuhn-Tucker’, a globalization strategy based on decreasing the KKT error is applied.

With the default setting ‘Filter’, a globalization strategy using a filter based on the objective and constraint violation is applied.

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