Since an activity's immediate successors cannot start until the activity finishes,
this rule is saying that the activity must finish in time to enable all its immediate
successors to begin by their latest start times. For example, consider activity M in

(No such variable is needed for activity A, since an activity that begins the project
is automatically assigned a value of 0.) By treating the FINISH node as another
activity (albeit one with zero duration), as we now will do, this definition of y, ...
