BARON: terminates solver when solution does not improve after x amount of time

GAMS

Hi everyone,

It is possible to define a termination criteria wherein the solver will terminate when a solution cannot be found after a specified amount of time?

Neither the user and solver manuals talk about this.

Any help is greatly appreciated!

Not with BARON. Some solvers allow you “user defined” termination via callbacks and this is made available to GAMS users, see e.g. https://www.gams.com/latest/docs/S_CPLEX.html#CPLEXmipstopexpr.
