Eli Towle commented,
Does the latest version of Gurobi (12.0.0) also fail to find one of the optimal solutions when setting PoolSearchMode to 2? If so, can you please write out an MPS model file and post the file conte...

Eli Towle commented,
Thanks for reporting this issue. I'll open a support ticket on your behalf so we can investigate further.

Eli Towle commented,
The correct reaction mechanism is [1,0,0,1] and the correct rate constant is 0.3. Is the system were to predict this exact values the MSE and thus the objective should be very close to 0 (a few si...

The issue I am encountering is that even when I provide my system with the right reaction and rate constant as an initial guess, I get the same reaction (wrong) as when I don't. Gurobi searches f...

Eli Towle commented,
The condition I described in the post you referenced is a sufficient condition for a variable to appear in the objective function of an LP file with a \( 0 \) coefficient: Variables that are added...

If the MST start does not provide an incumbent solution are the values still used to start? No. However, if the MIP start does not produce an initial feasible solution, Gurobi might later try to ...

Eli Towle commented,
An HNT file is used to store variable hint values and variable hint priorities. Variable hints are different from solution vectors and MIP starts. The article What are the differences between MIP S...

Your code is very close! You first create a Gurobi environment named \(\texttt{env}\) using your WLS license credentials, then associate that environment to a Model object called \(\texttt{model}\)...

Yes, you did not explicitly name the quadratic constraint. If you want to name the quadratic constraint and get rid of the warning, you can pass the \(\texttt{name}\) keyword argument to Model.addC...

Eli Towle commented,
Do you have a minimal reproducible example? I would expect the constraint to be included in the model file with the default name (e.g., \(\texttt{qc0}\)). Note you can always give the constraint a ...
