For example, define $S (G) = 1$ if $1$ and $2$ are nodes of $G$ and there is an edge from $1$ to $2$, and $0$ otherwise. But the only functions we care about are those which respect graph isomorphism. Share Cite Follow edited May 22, 2024 at 22:46

WebGraph Invariants and G. Tinhofer, M. Klin Published 1999 Mathematics This paper deals with graph invariants and stabilization procedures. We consider colored graphs and their automorphisms and we discuss the isomorphism problem for such graphs. Various global and local isomorphism invariants are introduced.

The Wiener index is probably the most studied graph invariant in both theoretical and practical meanings (cf. [4,6–11,22]). Apart from the Wiener index, we will consider some other related indices. dhs on fulton in chicago
