Re: the solver found integer solution

Hi Fred,
Thanks for your reply.
I have no idea to deal with my programm now. I just want to solve it with the status "1 optimal" through adding some constrains. In this case, could you tell me how to modify it?

No, unfortunately I can't. That's not how things work.
I assume that your model is a description of an actual problem. As mentioned before, it is not unusual that it can take a long time to solve a MIP (especially when outdated software is used). You cannot just add some arbitrary constraints to get an optimal solution quickly. Often, there are many ways to model one and the same problem. There is a chance but no guarantee that there are alternative formulations for your problem that can be solved quicker. I cannot dive so deep into your problem to investigate that.
