Matching of Bipartite Graphs using NetworkX

WebHopcroft Karp algorithm requires that we construct the maximal set of shortest augmented paths that don't have any common vertex between them. /// 5. Then so symmetric difference of existing matching and all augmented paths to get the new matching. /// 6. Repeat until no more augmented paths are found. WebAbstract. This paper surveys the techniques used for designing the most efficient algorithms for finding a maximum cardinality or weighted matching in (general or bipartite) graphs. It also lists some open problems concerning possible improvements in existing algorithms and the existence of fast parallel algorithms for these problems.
