I have a question regarding the behaviour of the branch and bound procedure when solving a large MIP model.
When I establish my stopping criterion as a given maximum time, the branch and bound procedure log shows the same behaviour as when I set the stopping criterion to a maximum number of found solutions = 2 or higher, ex. model.set(GRB.IntParam.solutionLimit,2).
But, when I set the stopping criterion to max solution = 1, the behaviour of the branch and bound is no longer the same.
This is quite strange to me, as that is the only change I'm making.
I appreciate any clarification on what may be happening.
Thank you very much
