The generic push-relabel approach is less effective than the relabel-to-front algorithm. The basic operations of push and relabel can be used in any order when using the push-relabel method. The relabel-to-front algorithm carefully selects the order and ...

WebPush-Relabel algorithm takes a different approach, it works with pre-flow (conservation constraint is violated — the amount of flow into a vertex can exceed the amount of flow exiting it, the difference ( flow_in-flow_out) in the amount present at that vertex is called excess, excess >= 0). This algorithm starts with a pre flow and terminates ...

WebJun 2, 2024 · Don't use a list. A list can do fast inserts and removals of items only at its end. You'd use pop (-1) and append, and you'd end up with a stack. Instead, use collections.deque, which is designed for efficient addition and removal at both ends. Working on the "front" of a deque uses the popleft and appendleft methods.
