Web5 jan. 2024 · New Algorithms and Lower Bounds for All-Pairs Max-Flow in Undirected Graphs Amir Abboud, Robert Krauthgamer, Ohad Trabelsi We investigate the time-complexity of the All-Pairs Max-Flow problem: Given a graph with nodes and edges, compute for all pairs of nodes the maximum-flow value between them. WebWe shall study the more general case where lower and upper bounds for the flow can be modified in order to make the given flow become a maximum flow. This 14 A. Deaconu …
