# Chordal¶

Algorithms for chordal graphs.

A graph is chordal if every cycle of length at least 4 has a chord (an edge joining two nodes not adjacent in the cycle). http://en.wikipedia.org/wiki/Chordal_graph

 is_chordal(G) Checks whether G is a chordal graph. chordal_graph_cliques(G) Returns the set of maximal cliques of a chordal graph. chordal_graph_treewidth(G) Returns the treewidth of the chordal graph G. find_induced_nodes(G, s, t[, treewidth_bound]) Returns the set of induced nodes in the path from s to t.
