PPT-Bipartite Matching and

Other Graph Algorithms Bipartite graph and Bipartite matching Bipartite graph Divide into two groups A and B All edges are from something in group A to something in group B Bipartite matching Want to uniquely match one item from group A with one item in group B.

The . bipartite graph matching problem.  is to find a set of unconnected edges which cover as many of the vertices as possible. If we select the set of edges.
