Hi Michel. Great video. Just one question: in the case that xij = 0, yi - yj is going to be smaller than 0, as i is predecessor of j right? Therefore, I don't understand how the constraint proofs anything. Could you clarify?

Hi Michel, thanks so much for the in depth explanation. But I've a doubt: why is yj - y1 >= 1 and not yj - y1 = 1?

Because we want to apply the method of optional constraints. See the book p. 600.
