Dear Tobias Achterberg If you specify values for only some of the variables, Gurobi will try to find values for the remaining ones by solving a sub-MIP. For example, say I have a problem with two...

Dear Jaromił Najman When you ctrl+c the run, do you see that one kind of cuts is added way more than others? You could try turning off this particular type of cuts via the corresponding parameter....

I solved this problem based on the answer given in Adding Consecutive Shifts COnstraint – Gurobi Help Center. 

 Dear Jaromil, Is there a particular reason why you create a copy of your model instead of directly working with the original model? No. Anyway, I wanted to save the solution file for later inspe...

This is a quite complex situation. You are saying that solving your model without the complicating continuity constraints (I'll just call them ccc) seems "easy", but when you add ccc then finding ...

Thank you for the explanation. 

Hello Jaromil, For example, let us say we have an electric bus routing problem with the charging schedule. So we have the trip timetable that is given. We need to find the minimum number of buses t...

Sorry for the late reply. I did experiment with and without it. Without the MemLimit parameter, the OS takes care of the problem, but that occurs later. So probably, the behavior of Gurobi MemLimit...

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.
