MAXMIPSOL
|
Description
|
Branch and Bound: Specifies a limit on the number of
integer solutions to be found by the Optimizer. The solve terminates once this limit is reached. It is possible that during optimization the Optimizer will find the same objective solution from different nodes. However,
MAXMIPSOL refers to the total number of integer solutions found, and not necessarily the number of distinct solution values.

Notes
|
Setting
MAXMIPSOL=1 can alter the solution path as this will put the emphasis on finding any feasible solution by triggering additional heuristics.
When
MAXMIPSOL is set on an objective using
XPRSsetobjintcontrol, then when the limit is reached the solver will stop the current solve but will continue with solving the next objective. This is in contrast to the behaviour when
MAXMIPSOL is set on the problem with
XPRSsetintcontrol, where the overall optimization will be terminated as soon as the limit is reached.
