max_clique(G)[source]

Find the Maximum Clique

Finds the O(|V|/(log|V|)^2) apx of maximum clique/independent set in the worst case.

Parameters:G (NetworkX graph) – Undirected graph
Returns:
  • clique (set) – The apx-maximum clique of the graph
  • Notes
  • ——
  • A clique in an undirected graph G = (V, E) is a subset of the vertex set
  • C \subseteq V, such that for every two vertices in C, there exists an edge
  • connecting the two. This is equivalent to saying that the subgraph
  • induced by C is complete (in some cases, the term clique may also refer
  • to the subgraph).
  • A maximum clique is a clique of the largest possible size in a given graph.
  • The clique number \omega(G) of a graph G is the number of
  • vertices in a maximum clique in G. The intersection number of
  • G is the smallest number of cliques that together cover all edges of G.
