Hi everyone,

I want to stop my program when is running. I want to stop it after 25 iterations if the solution doesn't change. How could I do it?

Thanks!

Hi Susana,

You could implement a callback function in which you have a counter which is incremented every time the solution did not change compared to a previous check. This callback function would check the current best objective value MIPNODE_OBJBST in a MIPNODE callback. Once a given criterion is met, you can use the terminate method to terminate the optimization process from within a callback.

Best regards,
Jaromił
