Hi Maliheh, Thank you for the explanation.    However, I don't really understand why such a constraint would affect the value space of variable `x`. Since `d` is not associated with any objective f...

Thank you! It helps.      Danning

Thank you Jonasz and Jaromił. This helps a lot.   Danning

Hi, Thank you!  I wonder by the design of Gurobi, will these two methods help accelerate the optimization or reduce the search space?     Danning

Hi,   Thank you so much for the explanation.  I found where the problem is. If I define the `d` as this : d = m.addVars(2, vtype=GRB.BINARY)for i in range(2): m.addGenConstrIndicator(d[i], True, ...

Hi Maliheh,    Thanks for the clarification. For the variable `d`, the formal definition is: `d_i = 1 if \sum_{1\leq j \leq m} x_{i,j}\geq 1`, in this case `m=2` `d_i = 0      otherwise` For the de...
