Yes, I saw it. We will be in touch through the ticket.  Best regards, Maliheh

I have sent a response to the email address associated with your Gurobi account. Could you please check your inbox and spam folder for an email from Gurobi Experts? Maliheh

Hi Panca,  Please look for my response to the ticket created in our Help Center for this issue. Best regards, Maliheh  

As explained in a similar post, duplicate lazy cuts in MIPSOL callbacks with Threads=1 can be explained. However, I do not expect to see duplicated lazy cuts in MIPNODE with Threads=1. Please post ...

The coefficient matrix only starts from 9e-6 which is almost 1e-5. Do you still think that it is a serious issue? As explained in the Gurobi Numerical Guidelines section "Advanced User Scaling," ...

Thanks for the clarification. Since this is a different question from your original modelling question, it would have been best to create a new post in the Algorithms section and mention that this ...

There is already a post addressing the question related to Gurobi's performance on the MIQCP model (see MIQP Model taking forever to compute). Please avoid cross-posting the same question. All post...

Hi Panca,  It seems like the cuts are not directly added to the model just in scenario (2).  Despite lazy cuts, user cuts are not necessarily added to the LP relaxation immediately. They must fir...

Hi,  The model numerics are not great mainly because the coefficient matrix spans over a wide range of 7 orders of magnitude. However, using Gurobi version 11.0.3 and NoRelHeurTime=60, the gap is a...

Does the bound come from the dual of the root relaxation? Yes, algorithms such as simplex and barrier are iterative approaches that improve the bound at each iteration. The root relaxation was ...
