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...

Gurobi does not modify the model as defined by the user. Variables that are added to the model but are not used in the constraints/objective appear in the objective function of the LP file with a \...
-
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 ...
-
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...
-
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 ...

Your constraint is m1.addConstr((sum(b[s + 1] - b[s]) * (eta[s] ** 2) for s in var_new) <= nu[0]) Notice that the \(\texttt{for s in var_new}\) is outside of the \(\texttt{sum()}\) function, creat...
