How can I make my constraint choose the max value?
AnsweredI have defined x[t], y[t], z[t], and I would like a set of constraints over time such that
for t in range (0,100)
m.addConstr(x[t], gurobipy.GRB.EQUAL, max_(y[t],z[t]))
However, I am getting the error name 'max_' is not defined. How do I resolve this.
Regards

You should use the overloaded form of addConstr as follows:
m.addConstr(x[t] == max_(y[t], z[t]))
Alternatively, you can use addGenConstrMax:
m.addGenConstrMax(x[t], [y[t], z[t]])

Thank you very much. The first syntax does not work for me but the second one does.

Glad to hear it works. There was a ")" missing in the first one. I updated it accordingly. It should work too.

I get the same error with the first syntax, i.e. "name 'max_ ' not defined'
Could it be a limitation of the editor I am using?

The \(\texttt{max_}\) function is part of the \(\texttt{gurobipy}\) module. Thus, in your case, you have to access it via
gurobipy.max_(y[t], z[t])
