Abstract

In this paper, we study the problems of enumerating cuts of a graph by non-decreasing weights. There are four problems, depending on whether the graph is directed or undirected, and on whether we consider all cuts of the graph or only s-tcuts for a given pair of vertices s, t. Efficient algorithms for these problems with ${\tilde{\mbox{O}}}(n^2m)$ delay between two successive outputs have been known since 1992, due to Vazirani and Yannakakis. In this paper, improved algorithms are presented. The delays of the presented algorithms are O(nmlog(n2/m)).
