An efficient algorithm for the minimum capacity cut problem in large sparse graphs.

ABSTRACT
Given a finite undirected graph with nonnegative edge weights the minimum capacity cut problem consists of partitioning the graph into two nonempty sets such that the sum of the weights of the edges connecting the two parts is minimum among all possible partitionings. The standard algorithm to calculate a minimum capacity cut, due to Gomory & Hu [1961], runs in O(n^4) time and is difficult to implement. We present an alternative algorithm whose worst-case bound is the same but which is easier to implement and was found empirically to be far superior to the standard algorithm on large sparse graphs.
