Do large implied variable ranges in nonlinear terms affect numerical stability, or only explicit coefficients and rhs matter?
I have a question about numerical scaling guidelines in Gurobi.The documentation emphasizes keeping matrix coefficients, RHS values, and bounds within reasonable ranges as shown here. However, I am...

Is it better to split nonlinear expressions into auxiliary variables or keep them in a single constraint?
AnsweredWhen dealing with nonlinear expressions, is it better to keep a single constraint with multiple bilinear and/or quadratic terms, or to introduce auxiliary variables to break it into smaller parts?F...

Do we need bounds for all newly introduced variables when reformulating nonlinear constraints?
AnsweredWhen modeling nonlinear constraints in Gurobi, I introduce new variables to convert them into bilinear or quadratic forms.My question is:Do we need to set lower and upper bounds for all newly intro...
