Direct Step Interval
Type : Integer
Range : {0..1000000}
Default : 10
This option controls the maximum number of consecutive conjugate gradient (CG) steps before Knitro will try to enforce that a step is taken using direct linear algebra. This option is only valid for the Interior/Direct algorithm and may be useful on problems where Knitro appears to be taking lots of conjugate gradient steps.
Setting the value to 0 will try to enforce that only direct steps are taken which may produce better results on some problems.
