Thank you. I will try that. So in general, can we say that indicator constraints perform better than bilinear and quadratic constraints?

Thank you Jaromil. I tried your suggestion. H 0 0 1547.9138011 1400.00000 9.56% - 279s 0 2 1400.00000 0 35 1547.91380 1400.00000 9.56% - 282s ...

Thank you very much. Yes, I missed that when I sum over the binaries, it turns out to be an integer value.I post the progress above. You see that the dual bound is stuck. By 300s, the incumbent is ...

I also attach a screenshot of the post.

Hello Jaromil, Here is the particular linearized constraint. self is an instance of a Gurobi model. _x is binary, _z is continuous in the range [0, 1], e_high and e_low are the big-M's I play with....

OK, I will try that. When a continuous variable is defined, I thought (-inf, _nf) bounds are implied. I missed that the default lower bound is 0 Thank you very much.

Dear Jonas, Thank you for the reply. x[386,135,t2] = 0 and x[386,135,t1] = 0 because they are coming from a partial solution. So Gurobi also knows it. You are right. en[46,135] is continuous. Buddi

Thank you for the answer. Do you think implementing such a message-passing mechanism makes sense as a new feature request for a future release? It might help to improve the performance of the solver.
