Web12 jul. 2024 · By using small vertex separators, the execution of each phase takes Õ (m) time on average. For planar graphs, we combine our algorithm with efficient shortest path data structures to obtain a minimum-cost perfect matching in Õ (n^6/5 (nC)) time. This improves upon the recent Õ (n^4/3 (nC)) time algorithm by Asathulla et al. [SODA 2024]. WebContribute to EbTech/rust-algorithms development by creating an account on GitHub.

In computer science, the Hopcroft–Karp algorithm (sometimes more accurately called the Hopcroft–Karp–Karzanov algorithm) is an algorithm that takes a bipartite graph as input and produces a maximum-cardinality matching as output — a set of as many edges as possible with the property that no two edges share an endpoint. It runs in time in the worst case, where is set of edges in the graph, is set of vertices of the graph, and it is assumed that .
