Adding one more observation: OutofMemory is observed right at the end of the presolve. 

Thanks a lot (also for the reference paper). I will study the problem a bit more with the paper you linked to as well and if I find a good, working solution I will post it here. 

Dear Maliheh, I thought about it, but the challenge is I have a large time horizon, and with other decision variables, the model becomes very expensive to run. Therefore, I'm looking for a strategy...

In other words, relaxation = 0 means it is a feasible solution, right?

Dear Jaromil, May I also clarify the meaning of "relaxation" in "Found phase-1 solution: relaxation 32"? Thank you.   

Thank you for the clarification. I thought NoRel heuristic generated a relaxed solution. 

Thank you. I also notice that this phase 1 solution is later ignored when the solver calculates the root relaxation and the starting best bound. Do you know why? If I understand correctly if the ph...

Hi, thank you for the insight. I'm trying to use computeIIS, only including that particular constraint. From the documentation, "To give an example of when these attributes might be useful, consid...

Thanks for the reply. The original problem is pretty big. Let me try to generate a smaller example code in the next few days to reproduce the error and post it. 

Thank you. I think this works for me. I also have another question, but since it is not directly a follow-up to this thread, I posted it here.  Appreciate if you could have a look at it as well.  B...
