The gap quickly drops to 2.22% (several hours). However, it constantly reports 2.22% but no more drops, lasting three days!

May I know what happened? Will it drop further?

  Hi Chao,

  if your model doesn't solve after this much time, it is most likely a very difficult one. To remedy this, you might want to reformulate it or seek other ways to strengthen its formulation. This talk is a great starter.

  You may want to tell us more about the problem you're solving. We might be able to give you some hints as to how to improve the formulation.

  Best regards
  Jonasz
