WebSep 29, 2024 · A matching of vertices in a graph. A matching of an undirected graph is a set of edges such that each vertex is incident on at most one matched edge. When each vertex is incident on exactly one matched edge, the matching called perfect. This class is used in igraph to represent non-perfect and perfect matchings in undirected graphs.

"WebGraphs in Python can be represented in several different ways. The most notable ones are adjacency matrices, adjacency lists, and lists of edges. In this guide, we'll cover all of them. When implementing graphs, you can switch between these types of representations at your leisure. First of all, we'll quickly recap graph theory, then explain ... " - Graph matching python
