Abstract

We propose a purely combinatorial algorithm for \mkvc in bipartite graphs, achieving approximation ratio~0.7. The only combinatorial algorithms currently known until now for this problem are the natural greedy algorithm, that achieves ratio 0.632, and an easy~2/3-approximation algorithm presented in \citeDBLP:journals/corr/BonnetEPS14.
