81Girvan-Newman algorithm — The Girvan Newman algorithm is one of the methods used to detect communities in complex systems.Girvan M. and Newman M. E. J., Proc. Natl. Acad. Sci. USA 99, 7821 7826 (2002)] The notion of a community structure is related to that of clustering,… …
82Matching (graph theory) — In the mathematical discipline of graph theory, a matching or independent edge set in a graph is a set of edges without common vertices. It may also be an entire graph consisting of edges without common vertices. Covering packing dualities… …

88Arboricity — The arboricity of an undirected graph is the minimum number of forests into which its edges can be partitioned. Equivalently it is the minimum number of spanning trees needed to cover all the edges of the graph.ExampleThe figure shows the… …
89König's theorem (graph theory) — In the mathematical area of graph theory, König s theorem describes an equivalence between the maximum matching problem and the minimum vertex cover problem in bipartite graphs. Setting A graph is bipartite if its vertices can be partitioned into …
