TIMELIMIT

Description
The maximum time in seconds that the Optimizer will run before it terminates, including the problem setup time and solution time. For MIP problems, this is the total time taken to solve all nodes.
Type
Double
Topic area
Limits
Values
≥0 
Stop LP or MIP search after the given number of seconds.
Default value
1e+20
Unit
seconds
Notes
This control has been newly introduced with Xpress Optimizer version 9.0 and should be used instead of the deprecated MAXTIME control. Note that the meaning of positive values differs between TIMELIMIT and MAXTIME. When both controls are set, TIMELIMIT takes precedence. The functionality of positive MAXTIME values is covered by SOLTIMELIMIT.
When TIMELIMIT is set on an objective using XPRSsetobjdblcontrol, 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 TIMELIMIT is set on the problem with XPRSsetdblcontrol, where the overall optimization will be terminated as soon as the limit is reached.
When a TIMELIMIT of 0 is set, the solver will stop immediately.
Affects routines
