Linear Programming Based Approximation Algorithms for Feedback Set Problems in Bipartite Tournaments
16 years 1 months ago
We consider the feedback vertex set and feedback arc set problems in bipartite tournaments. We improve on recent results by giving a 2-approximation algorithm for the feedback vert...
