public abstract class VF2AbstractIsomorphismInspector<V,E> extends java.lang.Object implements IsomorphismInspector<V,E>
Base implementation of the VF2 algorithm using its feature of detecting isomorphism between two graphs as described in Cordella et al. A (sub)graph isomorphism algorithm for matching large graphs (2004), DOI:10.1109/TPAMI.2004.75, http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=1323804This implementation of the VF2 algorithm does not support graphs with multiple edges.
