Chapter 6. Set the solver termination time

If your planning application does not have a termination setting or a termination event, it theoretically runs forever and in reality eventually causes an HTTP timeout error. To prevent this from occurring, use the optaplanner.solver.termination.spent-limit parameter to specify the length of time after which the application terminates. In most applications, set the time to at least five minutes (5m). However, in the Timetable example, limit the solving time to five second, which is short enough to avoid the HTTP timeout.

optaplanner.solver.termination.spent-limit=5s
