摘要：

In this paper we give ratio 4 deterministic and randomized approximation algorithms for the FEEDBACK ARC SET problem in bipartite tournaments. We also generalize these results to give a factor 4 deterministic approximation algorithm for FEEDBACK ARC SET problem in multipartite tournaments. (c) 2007 Elsevier B.V. All rights reserved.
