## Defining a Modified Adjacency Value Product Following Unique Prime Labeling of Graph Vertices and Undertaking a Small Step Toward Possible Application for Testing Graph Isomorphism

**Authors:** Prashanth R. Rao

In a previous paper we described a method to represent graph information as a single numerical value by distinctly labeling each of its vertices with unique primes. In this paper, we modify the previous approach to again represent a graph as a single numeric value, we log transform this value and approximate it with an optimum value which if minimized by appropriate prime labeling of the graph should allow us to compare it with another graph on which an identical algorithm is implemented. Identical optimum value minima is a necessary but not sufficient condition for graph isomorphism.
