Hi Simon, The documentation suggests that quadratic constraints handle equality constraints. How do you know that the constraints were converted to an inequality form? Did you store the model someh...

Hi Jingyue, this article should shed some light. Writing a solution to an Excel sheet can be done for example by iterating over variables of the model and retrieving their value in each scenario, a...

Hi Tiril, 1. What are \(U1, U2\)? Are they variables? If so, you need to define them as such upfront, for example by: U1 = m.addVars(alternative, criteria, vtype="C", name="u1")U2 = m.addVars(alter...

Hi Johan, Did you set the NonConvex parameter to 2, as suggested in the article you linked? Additionally, for the second auxiliary variable, which you defined as: gp.max_(a[t], 1) for t in range (T...

I have too little information to tell. I used "_" in my codes and it never caused any trouble. If you like, you can share a minimal reproducible example of your code and we'll see what could cause ...

Generally, I would recommend giving all the variables a custom name to quickly distinguish one from the other. Then the .lp file will contain the user-defined variable names.  Just beware not to us...

You can write the complete model using model.write("model.lp") in Python API, although the file will not look exactly the way you want. But I believe it should not be too difficult to come up with ...

Hi Tiril! Could you share a minimal reproducible example of the code which throws the error? We will then be able to give you better advice. Best regardsJonasz
