WebFast C++ implementation of the Hungarian algorithm. This is an open-source implementation of the "O(N^3)" dynamic-programming version of the Hungarian algorithm, for weighted perfect bipartite matching. It's written with speed in mind, whilst trying to remain readable-ish. 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. bionic cobot festo
