The Hopcroft-Karp algorithm is an algorithm that takes a bipartite graph G (E,V) G(E,V) and outputs a maximum matching, M M. It runs in worst-case O\big (|E| \sqrt {|V|}\big) O(∣E ∣ ∣V ∣) time. The Hopcroft-Karp algorithm uses similar techniques as the Hungarian algorithm and Edmonds' blossom algorithm.

Hopcroft Karp Algorithm: Initialize Maximal Matching M as empty. While there exists an Augmenting Path p Remove matching edges of p from M and add not-matching edges of p to M (This increases size of M by 1 as p starts and ends with a free vertex) Return M. Below diagram shows working of the algorithm.

1 Hopcroft-Karp Algorithm Recall that the basic bipartite matching algorithm repeatedly nds an augmenting path and performs the operation M L E(P), where P is the augmenting path found at each iteration, until the graph has no more augmenting paths. The running time of the algorithm is O(mn), as an augmenting paths can

-1 I am working on graph algorithm theories (I am mathematician nothing with computer science yet) and I do have some matching problems to self, for which I am using Hopcroft-Karp for serious reasons ( Hopcroft-Karp algorithm ). I don't want to solve them by hand with it, so I would like to use a program for it.

The Augmenting path algorithm seen in class chooses one augmenting path in each iteration, even if it nds many augmenting paths in the process of searching. The Hopcroft-Karp algorithm improves the running time of the above algorithm by correcting this wasteful aspect; in each iteration it attempts to nd many disjoint augmenting paths, and it.

1 Hopcroft-Karp-Karzanov algorithm This is the algorithm that takes bipartite graph as an input and returns maximum cardinality matching. And now we can describe in detals what these terms mean. At rst we take bipartite graph. This is such kind of graph where we can group nodes in two groups. Within the group, nodes do not have any edges.
