Do you mean Google Colab instead of Corab? As mentioned in our Google Colab licensing and installation article, when installed via pip, gurobipy comes with a size-limited trial license that can sol...

Hi Tianyu, As explained in the article Why does Gurobi sometimes return non-integral values for integer variables?, the solution value of a binary variable can deviate from 0 or 1. The tolerance fo...

Hi Vigneshwar, Model modification in Gurobi is performed in a lazy fashion, meaning that the modifications don't affect the model immediately. Instead, they are queued and are applied later, with t...

Hi Fei Wang, The solution x = array([[0.5, 1. ],       [0.5, 1. ]]) y = array([0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5]) is not feasible for the LP model you provided unless the \(u\) variables ...

Hi Jizhou Lu, The non-systematic behaviour with PoolSearchMode =1 comes from the fact that the set of solutions found by the solver depends on the exact path the solver takes through the MIP search...

Hi Myat, The error  "KeyError: 'Missing constraint index'" occurs when you try to add a single constraint using the method Model.addConstrs(). Please use Model.addConstr() instead of using Model.ad...

If there exists a simplex feasible/optimal basis for the continuous relaxation cause any subsequent issues when I change some of the variables to binary and then submit the problem to Gurobi to sol...

Hi,Could you please clarify the routine you plan to use to generate and add user cuts to the LP model? For example, if your approach is something like:Solve the LP → Run your custom separation rout...
