I want to put a stopping criterion, let say accept a relative gap of 1%.
So I have included the code:

execute PARAMS {
cplex.epgap = 0.01;
}

before the dvars. When I lunch a run, the engine keeps going passed 1%. It's like if it would ignore the stopping criterion. Since it did not work, I tried to change it directly in the .ops. Once again, I can't save the chage made to the .ops and when I close it and reopen it, I lose the change.

Anybody knows what's going on?

Hi,

About saving the .ops. We have a known bug in the OPL IDE. Saving one .ops file sometimes does not work. If you use the save all button, it will work.

About modifying the CPLEX parameters, can you post a short model reproducing it ?

Thanks,

Alain
