WebFeb 12, 2013 · The proof is a one-liner: Theorem: A maximum matching M never contains the cheaper edge of AB and BA for any two vertices A,B. Proof: Let M be a maximum matching. Suppose AB is in M and is cheaper than BA. Define M' = M - {AB} + {BA}. M' is clearly still a matching, but it's more expensive.

WebJun 30, 2010 · Given a bipartite graph (one in which all edges go between the two parts), the Hungarian algorithm finds a matching (i.e., a set of disjoint edges) of maximum size. The algorithm starts with any matching (the empty matching is used here) and constructs a tree via a breadth-first search to find an augmenting path: a path that starts and … WebThe Hungarian algorithm is based on the concept of augmenting paths to find ways to increase the matching [35].
