POOLKEEPSOLS

Description
Limits the number of collected solutions that should automatically be transferred into a next solve. Solutions collected from a MIP solve or from a Global solve can be transferred automatically as warm-start solutions for a subsequent solve, by setting this control to a positive value. Solutions will be transferred the first time a problem is modified after having been solved, or at the start of the next solve if no modifications were applied. The warm-starting is equivalent to calling XPRSaddmipsol on the POOLKEEPSOLS best solutions stored in the pool and therefore supports any solve type that can be warm-started by XPRSaddmipsol.
Type
Integer
Topic area
Solution Pool
Values
-1 
Use all collected solutions as warm-starts for the next solve.
0 
Do not use any collected solutions for warm-starting
>0 
Use up to the given number of solutions as warm-starts for the next solve.
Default value
0
Note
Unlike warm-start solutions loaded by XPRSaddmipsol, automatically transferred solutions do not trigger a user callback function set by XPRSaddcbusersolnotify.
Affects routines
