Hi,

I am trying to add some min() and max() constraints to my model(). But the model generated doesn't have these constraints and doesn't provide any error information neither. The code of constraints is as follows, where the element in self.x  self.y and self.z are variable. Any help would be greatly appreciated!

self.m.addConstrs(self.z[i, j, k] == min_(self.x[i, j, k], self.y[i, j, k])
                  for i in set1
                  for j in set2
                  for k in set3)

  Hi,

  Could you please provide a minimal reproducible example? In particular, how do you see that

  the model generated doesn't have these constraints

  Did you write the constructed model to a file via the write method and cannot find the \(\min\) constraints?

  Best regards, 
  Jaromił
