Constructor Detail

BronKerboschCliqueFinder

public BronKerboschCliqueFinder(Graph<V,E> graph)

Creates a new clique finder.

Parameters:

graph - the graph in which cliques are to be found; graph must be simple

Method Detail

getAllMaximalCliques

public Collection<Set<V>> getAllMaximalCliques()

Finds all maximal cliques of the graph. A clique is maximal if it is impossible to enlarge it by adding another vertex from the graph. Note that a maximal clique is not necessarily the biggest clique in the graph.

Returns:

Collection of cliques (each of which is represented as a Set of vertices)

getBiggestMaximalCliques

public Collection<Set<V>> getBiggestMaximalCliques()

Finds the biggest maximal cliques of the graph.

Returns:

Collection of cliques (each of which is represented as a Set of vertices)
