# GLOBALLSHEURSTRATEGY

Description | When integer-feasible (for MINLP, any solution for NLP) but nonlinear-infeasible solutions are encountered within a global solve, the integer variables can be fixed and a local solver (as defined by the LOCALSOLVER control) can be called on the remaining continuous problem. This control defines the frequency and effort of such local solves.
Type | Integer
Topic areas | Global, Heuristics
Values |
-1 | Automatic selection of the strategy.
0 | Never run a local solver on a partially fixed solution.
1 | Conservative strategy.
2 | Moderate strategy.
3 | Aggressive strategy.
Default value | -1
Affects routines | XPRSoptimize ( OPTIMIZE).
