text: In the multiway cut problem we are given a weighted undirected graph G=(V,E) and
a set T⊆V of k terminals. The goal is to find a minimum weight set of edges E′⊆E with
the property that by removing E′ from G all the terminals become disconnected.
In this paper we present a simple local search approximation algorithm for the
multiway cut problem with approximation ratio 2−2k . We present an experimental
evaluation of the performance of our local search algorithm and show that it greatly
outperforms the isolation heuristic of Dalhaus et al. and it has similar performance
as the much more complex algorithms of Calinescu et al., Sharma and Vondrak, and
Buchbinder et al. which have the currently best known approximation ratios for
this problem.
