In mathematical optimization, the push–relabel algorithm (alternatively, preflow–push algorithm) is an algorithm for computing maximum flows in a flow network. The name "push–relabel" comes from the two basic operations used in the algorithm. Throughout its execution, the algorithm maintains a … See more The concept of a preflow was originally designed by Alexander V. Karzanov and was published in 1974 in Soviet Mathematical Dokladi 15. This pre-flow algorithm also used a push operation; however, it used … See more Definitions and notations Let: • G = (V, E) be a network with capacity function c: V × V → $${\displaystyle \mathbb {R} }$$∞, • F = (G, c, s, t) a flow network, where s ∈ V and t ∈ V are chosen source and sink … See more The generic push–relabel algorithm is used as a proof of concept only and does not contain implementation details on how to select an active … See more While the generic push–relabel algorithm has O(V E) time complexity, efficient implementations achieve O(V ) or lower time complexity by enforcing appropriate rules in selecting applicable push and relabel operations.
