chordal_graph_cliques¶
- chordal_graph_cliques(G)[source]¶
Returns the set of maximal cliques of a chordal graph.
The algorithm breaks the graph in connected components and performs a maximum cardinality search in each component to get the cliques.
Parameters : G : graph
A NetworkX graph
Returns : cliques : A set containing the maximal cliques in G.
Raises : NetworkXError
The algorithm does not support DiGraph, MultiGraph and MultiDiGraph. If the input graph is an instance of one of these classes, a NetworkXError is raised. The algorithm can only be applied to chordal graphs. If the input graph is found to be non-chordal, a NetworkXError is raised.
Examples
>>> import networkx as nx >>> e= [(1,2),(1,3),(2,3),(2,4),(3,4),(3,5),(3,6),(4,5),(4,6),(5,6),(7,8)] >>> G = nx.Graph(e) >>> G.add_node(9) >>> setlist = nx.chordal_graph_cliques(G)
