Maximum Matching on Regular Nonbipartite Graphs
It is proved that any blocking flow-type maximum matching algorithm based on finding shortest augmenting paths runs in O(n^2) time on d-regular graphs, both bipartite and nonbipartite, and that the classic matching algorithms automatically outperform [Yus13, DH25].
