    Thank you! I tried to compute IIS, but it also didn't help. In the case of model.optimize(), the solver has been trying to find a solution for a long time and went through different branches in the...

    Checking feasibility of the problem

    Ongoing

    Hello! I'm sure that my problem is infeasible, but the solver has been trying to find a feasible solution for a long time. Are there any methods to determine whether the problem is feasible or not?...

    Thanks. Can you please answer one more question?I noticed that the CPU usage was around 100% during the problem construction, which means that all CPUs were working to their fullest. But during the...

  • Andrey Kihtenko commented,

    Since the solving of the problem occurs on the Gurobi server, then does it no matter which server the user has? Is it only important that the user's server allows quickly constructing the problem? ...

    Thank you! It helped me to find a time-consuming block.  Do I understand correctly that the general scheme is as follows? Problem construction; Sending it to the Gurobi server; Solving on the Guro...
