I have a problem with the following form where f and h are linear functions, and g(x,y) is a nonlinear function. If I fix x, g(x,y) will be a non-convex quadratic function. If I fix y, g(x,y) will...

I want to write the model into rlp format and write a solution which can be read back by the generated model by reading the rlp file.Is there a way to do this in gurobi?

I first solved a mip problem and write the solution to sol file or mst file. Then, I delete a few constraints and want to use the previous solution as a mip start. 1. Which is the right way to rest...

What's the meaning of this warning? What action can trigger this warning?

def process_expr(expr: LinExpr): c = 0 remove_vars = [] for i in range(expr.size()): var = expr.getVar(i) if var.VarName.startswith("A"): c += expr.getCoeff(i) * m...

What does gurobi do after the root relaxation and before branch and bound?

How to limit the time spent in the root node, since I find after a long time in root node there's no new incumbent of my problem. I want the model to quickly proceed to the phase of branch and bound.

Is it possible to do that in GUROBI?

I want to use my user-defined constraints both as cut and lazy constraints. I know that: The cbCut will only add cut into the user cut pool and may not add these cuts immediately or not add at all...
