Hi Jaromił, Thanks for the information. I tried this model.addVars(my_list, vtype=GRB.BINARY, name="x") I got this error after adding a new constraint to the optimized model, as described above. ...

Hi Jaromił, Thanks for your response. My intuition was that re-solving the model was not as efficient as adding extra constraints using Callback. But, I realized that this, in fact, is what I was l...

ユーザーの入力を待っています。Hi, I want to solve a large LP problem with 1e5 variables, 1e9 constraints, and 1e12 non-zeros. I hope to solve this problem optimally, but any relaxed solution could also be helpful. I check Gurob...

Thanks, Jaromił. Based on what I learned, Gurobi adds cuts only for children nodes of the current node in a B&B tree. However, what I am looking for is to add cuts for all nodes. I wonder whether t...

Can we add cuts to all nodes of the B&B tree based on an incumbent solution?
回答済みAs I realized Gurobi cbCut function adds cuts to the current relaxed node. I want to add some cuts to every relaxed node in the B&B tree based on an incumbent solution. I wonder if this is possible...
