XKTR_PARAM_BAR_MAXBACKTRACK, KNITRO_PARAM_BAR_MAXBACKTRACK
|
Description
|
Indicates the maximum allowable number of backtracks during the linesearch of the Interior/Direct algorithm before reverting to a CG step.
|
|
Type
|
Integer
|
|
Default value
|
3
|
|
Note
|
Increasing this value will make the Interior/Direct algorithm less likely to take CG steps. If the Interior/Direct algorithm is taking a large number of CG steps (as indicated by a positive value for 'Gits' in the output), this may improve performance. This option has no effect on the Active Set algorithm.
