# SOLTIMELIMIT

Description | The maximum time in seconds that the Optimizer will run a MIP solve before it terminates, given that a solution has been found. As long as no solution has been found, this control will have no effect.
Type | Double
Topic area | Limits
Values |
0 | The value is ignored.
>0 | If an integer solution has been found, stop MIP search after the given number of seconds, otherwise continue until an integer solution is finally found.
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. It can be combined with the TIMELIMIT control. When SOLTIMELIMIT 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 SOLTIMELIMIT is set on the problem with XPRSsetdblcontrol, where the overall optimization will be terminated as soon as the limit is reached. A SOLTIMELIMIT of 0 has no effect.
Affects routines | XPRSmipoptimize ( MIPOPTIMIZE).
