Note that this inspector only finds isomorphisms between a smaller graph and all induced subgraphs of a larger graph. It does not find isomorphisms between the smaller graph and arbitrary subgraphs of the larger graph. For example, given as input the cubical graph $Q_{3}$ and the square graph, isomorphic mappings will be found between the square and the faces of the cube. However, given the complete graph $K_{5}$ and the square graph as input, no isomorphisms will be found since all induced subgraphs of a complete graph are themselves complete graphs.
Consequently, in the case where both input graphs have the same number of vertices, this
algorithm is equivalent to running VF2GraphIsomorphismInspector
.
This implementation of the VF2 algorithm does not support graphs with multiple (parallel) edges.
