Poster title: Conjectures of Graffiti.pc on the Chromatic Number of a Graph
Abstract: The chromatic number of a graph is the smallest number of colors needed to color vertices such that no two adjacent vertices share the same color.  It was first proven that the chromatic number of a graph is at most one plus the maximum degree of the graph.  In 1941, R. L. Brooks proved that if the graph is neither a complete graph nor an odd cycle, then the upper bound for the chromatic number of the graph can be reduced to just the maximum degree of the graph.  My project is to resolve conjectures whose statements are similar to Brooks’ Theorem. The conjectures are generated by Graffiti.pc, a conjecture making program designed by Dr. Ermelinda DeLaVina.
