Barrier Refinement

Type : Selection

Range : The settings listed below

Default : Off

This option specifies whether to try to refine the barrier solution for better precision. If enabled, once the optimality conditions are satisfied, Knitro will apply an additional refinement/postsolve phase to try to obtain more precision in the barrier solution. The effect is similar to the effect of enabling the Crossover Iteration Limit , but it is usually much more efficient since it does not involve switching to the Active Set algorithm. Possible values are:

• Off

• On

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