I understand I can do that, but that will generate 2 times the number of equality constraints and I think in certain situations, this reformulation will lead to numerical issues near the boundary. ...

Sorry to bother you. I have an additional question, I want to use lagrangian relaxation to both inequality and equality constraints. In the online doc, it says, For minimization problems, it's rel...

Thanks a lot, What's the standard form for gurobi? Does it mean gurobi would move all variables to the LHS, and leave constant in the RHS as a standard form? Since the 2nd and 3rd constraints are ...

I use an iterative framework, which first fixes x, then y, then x again. And I have a concern that in my previous post: https://support.gurobi.com/hc/en-us/community/posts/4974386567697/comments/60...

Sorry to add additional questions, I think I have a similar problem here: https://support.gurobi.com/hc/en-us/community/posts/6208930568721-fix-variables-to-convert-bilinear-QP-to-LP . You could t...

Thanks, that solves my problem. From your code, I finally realize that reading a sol file and a mst file has the same effect, which set the start attribute of each variable in the file, right? As t...

Thanks, but in my situation, I don't want to call optimize, which will cost a lot of time without any feasible solution. However, I have a mps and a sol to it, I want to convert the sol of mps into...

Sounds great, thanks.

You are removing all non-x variables in a for-loop 1 by 1. You can remove them all at once Your advice seems not working  

Thank you, From your reply, it means gurobi will treat the previous solution as a special MIP start, which is not open to the user, right? What about adding new constraints, if I assure the new con...
