HEURTHREADS

Description
Branch and Bound: The number of threads to dedicate to running heuristics during the root solve and tree search.
Type
Integer
Values
-1 
Automatically determined from the THREADS control.
0 
Disabled. Heuristics will be run sequentially with the root LP solve, cutting and tree search.
>=1 
Number of threads to dedicate to parallel heuristics.
Default value
0
Notes
When heuristic threads are enabled, the heuristics will be run in parallel with the root cutting and in parallel with the branch-and-bound tree search.
During the branch-and-bound tree search, a number of the allowed MAXMIPTASKS tasks will be reserved for parallel heuristics. This number of reserved tasks is given by HEURTHREADS.
Affects routines
XPRSmipoptimize ( MIPOPTIMIZE).
