Hi,

My MILP takes about 3 seconds to arrive at a solution most times. When other data with the same "size" and characteristics is used, it can sometimes take more than an hour.  What could be the possible cause?

Thank you!

  Hi Elisabeth,

  to give you some guidance, we need more information - the behavior you observe could have numerous causes.

  Could you tell us more about the problem you solve (its mathematical description would be great)?

  Could you also share the logs of one run which performs as expected and another one, which performs worse?

  Best regards
  Jonasz
