WebDec 2, 2024 · The Hungarian algorithm can be used to solve this problem. Minimum Weight Matching. In a weighted bipartite graph, a matching is considered a minimum weight matching if the sum of weights of the matching is minimised. The Karp algorithm can be used to solve this problem. Running Examples 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.
