WebCombinatorial relaxation algorithm can detect and correct the breakdown situation. And the maximum weight matching of bipartite graph is an important part of the combinatorial relaxation algorithm. In order to choose the proper method for the large-scale, dense … WebThe Hungarian method finds a perfect matching and a potential such that the matching cost equals the potential value. This proves that both of them are optimal. In fact, the Hungarian method finds a perfect matching of tight edges: an edge is called tight for a potential y if . Let us denote the subgraph of tight edges by .

WebSo we know our algorithm is nite if the matrix is integer (and hence also if it is rational). It is possible to analyze this algorithm a lot better (using knowledge of the maximum cardinality bipartite matching algorithm) and show that it runs in O(n3) time. The algorithm we derived is called the Hungarian algorithm.
