http://compalg.inf.elte.hu/~tony/Oktatas/TDK/FINAL/Chap%2010.PDF Webmatching on graphs, we deﬁne a new kind of equivalence on graph vertices. Since it can be used in various graph algorithms that explore graphs, we call it exploratory equivalence. The equivalence is based on graph automorphisms. Because many similar equivalences exist (some also based on automorphisms), we argue that this one is novel.
