GLOBALMISLPHEURSTRATEGY

Description
Controls how aggressively a set of MISLP-based root heuristics are run at the root node when solving an (MI)NLP to global optimality.
Type
Integer
Topic areas
Global, Heuristics
Values
-1 
XPRS_GLOBALMISLPHEURSTRATEGY_AUTOMATIC Automatic. The solver decides which heuristics to run and how aggressively, based on HEUREMPHASIS.
0 
XPRS_GLOBALMISLPHEURSTRATEGY_OFF Off. No root heuristics of this kind are run.
1 
XPRS_GLOBALMISLPHEURSTRATEGY_CONSERVATIVE Conservative. A small set of cheap root heuristics is run with tight effort limits.
2 
XPRS_GLOBALMISLPHEURSTRATEGY_MODERATE Moderate. A larger set of root heuristics is run with moderate effort limits.
3 
XPRS_GLOBALMISLPHEURSTRATEGY_AGGRESSIVE Aggressive. The full set of root heuristics is run with generous effort limits.
Default value
-1
Affects routines
