Ruixuan Liu commented,
Thanks! This is really helpful! Is there a way I can retrieve the constr obj (ie absconstr)? Cuz I'm trying to update the abs constraint on the fly, it would be nice if I can retrieve the abs cons...

Trouble using gp.abs_()
AnsweredHi, I'm trying to add a constraint using the abs_() function. I'm just doing a very simple example a = model.addVar(name="a")b = model.addVar(lb=-1, name="b")model.addConstr(a == gp.abs_(b), name="...

Thanks! This makes sense now. And one more question. If a few more new variables and constraints are added to the model for the second run, will the solver use the previous result to warm start by ...

Thank you so much for the prompt reply. Can I interpret it as the bottleneck in this particular problem is proving the solution is optimal rather than finding the solution? Cuz in my case, the sol...

AnsweredHi, I'm trying to reuse a previously optimized model as a warm start for the next run. But I'm not sure if I'm doing this correctly. The issue I'm having now is after solving the model, if I direct...
