We would like to implement a push-relabel algorithm in which we maintain a first in, first-out queue
Question:
We would like to implement a push-relabel algorithm in which we maintain a first in, first-out queue of overflowing vertices. The algorithm repeatedly discharges the vertex at the head of the queue, and any vertices that were not overflowing before the discharge but are overflowing afterward are placed at the end of the queue. After the vertex at the head of the queue is discharged, it is removed. When the queue is empty, the algorithm terminates. Show how to implement this algorithm to compute a maximum flow in O(V3) time.
