XKTR_PARAM_BAR_DIRECTINTERVAL
|
Description
|
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.
|
|
Type
|
Integer
|
|
Default value
|
10
|
|
Note
|
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 bar_directinterval to 0 will try to enforce that only direct steps are taken which may produce better results on some problems.
