Hi Marika,  Thanks for the answer.  Actually I'm using Gurobi 11.  It seemed to me that the parameter GRB_CB_MIPNODE_NODCNT  was not effective, so I replaced it with GRB_CB_MIP_NODCNT. With the one...

Hi Jaromił,  thank you for your answer.  I set the bounds to the variables participating in bilinear terms by adding additional constraints to the model. Can you suggest a better way to provide the...

Hi, I am facing a similar issue with Gurobi 10.0.1. By considering a minimization problem, I observed the following solutions:  1) with MIPGap=1%, in 21 seconds I found a solution with gap=0.9898%...

Hi Jaromił,  Thank you. Since the model is not reformulated in a mixed integer model, I still do not understand the meaning of the (optimality) gap that I see when I solve my model. Could you help ...

Hi Jaromił,  Thank you for your very clear answer.  If it is possible, I would like to ask you also another question related to the model: the log file shows "Continuous model is non-convex – solvi...
