The all pairs minimum cuts problem in a capacitated undirected network is well known. Gomory and Hu showed that the all pairs minimum cuts are revealed by a min-cut tree that can be obtained by solving exactly (n -1) maximum ow problems, where n is the number of nodes in the network. In this paper
The overall min-cut problem in a capacitated undirected network is well known. Recently Stoer and Wagner gave an elegant algorithm for finding such a cut. In this paper we present a parametric analysis of such a cut where the capacity of an arc {i, j } in the network is given by min{b ij , Ξ»}, where
We compare three lower bounds for the minimum cardinality of a multiway cut in a graph separating a given set S of terminals. The main result is a relatively short algorithmic proof for a simplified version of a min-max theorem of the first and the third authors asserting that the best of the three
