Default value

-1

Notes
|
If this is set to -1 (the default) then Xpress decides automatically which heuristics to run. Otherwise the value is interpreted as a bitset that indices which heuristics to run. 0 (zero) means not to run any large neighborhood search heuristics in the background.
Other types of background jobs are controlled by
BACKGROUNDSELECT.
