In the maximum matching problem we are asked to find a matching M of maximum size in a given input graph G = (V,E). The maximum matching problem in bipartite graphs can be easily reduced to a maximum flow problem in unit graphs that can be solved in O(m n) time using Dinic's ...
Maximum Bipartite Matching with Ford-Fulkerson takesO(VE)time. Using Dinic instead of Ford-Fulkerson (or Edmonds Karp for that matter; note that Edmonds Karp always find the shortest augmenting path instead of finding a random path), you can achieve a complexity of. ...
Finding a maximum bipartite matchingWe can use the Ford-Fulkerson method to find a maximum matching in an undirected bipartite graph G= (V, E) in time polynomial in |V| and |E|. The trick is to construct a flow network G= (V',E') for the bipartite graph G as follows. We let ...
