Multiple source, single sink maximum flow in a planar graph
Published 29 Aug 2010 in cs.DM and cs.DS | (1008.4966v1)
Abstract: We give an $O(n{1.5}\log n)$ time algorithm for finding the maximum flow in a directed planar graph with multiple sources and a single sink. The techniques generalize to a subquadratic time algorithm for bounded genus graphs.
