Bipartite matching and the hungarian method
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.

WebA maximum matching (also known as maximum-cardinality matching) is a matching that contains the largest possible number of edges. There may be many maximum … WebJul 25, 2016 · The linear sum assignment problem is also known as minimum weight matching in bipartite graphs. A problem instance is described by a matrix C, where each C[i,j] is the cost of matching vertex i of the first partite set (a “worker”) and vertex j of the second set (a “job”). ... The method used is the Hungarian algorithm, also known as ...
WebMay 23, 2013 · 4. Here are possible solutions using bipartite matching and the Hungarian algorithm. My proposed solution using bipartite matching might not be what you have … WebHungarian method for maximum matching in a bipartite graph is based on the idea of using an augmenting path to construct a new matching M ˙+1, of cardinality ˙+1, based on the given matching M ˙ of cardinality ˙. For a bipartite graph G= ( , , E), a matching M ⊆ Eis a subset of edges, and there is no two edges in Msharing the same vertex.
