Suppose we want to add a constraint that teams A and B must play in week 4 (we want the last game to be a divisional one). Given the current model, which of the following constraints would model this correctly? Select all that apply.
Explanation The second and third constraints would both model this correctly. We can either force the decision variable for week 4 to 1, or we can make sure that only one game is played in the earlier weeks.
