Bipartite Matching is in NC

RSS-Feed

Abstract:

We show that the bipartite matching problem is in NC. We extend the result to weighted bipartite matching and the computation of the noncommutative rank of a symbolic matrix. In particular, this implies that the decision version of linear matroid intersection is in NC as well. The techniques are based on the polynomial method, inspired from a construction of subspace design by Guruswami and Kopparty (Combinatorica 2016).
