# How to Convert Bipartite Matching to Independent Set

1 answer

The maximum bipartite agreement is a set of edges in a bipartite graph, where the two edges are not adjacent. The maximum independent set is the set of nodes (vertices) in the graph, two adjacent vertices.

So you can transform the bidirectional matching problem into an independent set by transforming each edge in your bipartite graph to a node, and then add a face between all the newly created nodes that share a common endpoint in the original graph. Then the maximum independent set in the new graph corresponds to the maximum bipartite agreement in the original problem.
