Hi Huan,Just to keep the information in one place, I'm quoting my response from your other post below in case it's useful for future readers: Yes, your observation can be correct for your particula...

Hi Huan,Yes, your observation can be correct for your particular model. A manually introduced bilinear reformulation could sometimes solve faster than modeling the nonlinear relationship directly.H...

Hi João,I'm not very familiar with prioritizr, so I will mostly answer from the Gurobi perspective. To summarize, I would not expect Gurobi 8.0.0 and 13.0.1 to necessarily return the same solution....

Hi Mengyu,The reported gap is not an error. It is the MIP gap, which measures how far the current best feasible solution could still be from the true optimum, based on the best objective bound avai...

Hi Liu,Thank you for the detailed description. Models with bilinear terms and integer variables fall into the class of nonconvex MIQCP/MIQCQP problems that Gurobi handles with a global algorithm.(1...

Hi Marco,Happy (soon-to-be) new year to you, as well!If your model includes bilinear terms, the most impactful modeling lever is usually tight variable bounds (especially on variables participating...

Hi Adriano,Support for Python 3.14 is planned for our next technical release, Gurobi 13.0.1, which is currently scheduled for Q1 2026. We've just updated our Knowledge Base article, “Which Python v...

Thank you for the detailed page references. We've confirmed the clipping in the current PDF and logged an internal ticket to investigate and track it. We'll also review similar tables. If you spot ...

Hi Taehyeon,When using a lazy constraint callback, Gurobi requires setting LazyConstraints=1. As described in the documentation for this parameter, this setting tells Gurobi to avoid model reductio...

Hi Lorenz,First, you may find our “How do I use multiprocessing in Python with Gurobi?” article helpful. It describes how the multiprocessing Python package can be used to implement process-based p...
