Let A be a graph coloring algorithm. Denote by -&-Agrave; (G) the ratio between the maximum number of colors A will use to color the graph G, and the chromatic number of G,x(G). For most existing polynomial coloring algorithms, -&-Agrave;(G) can be as bad as O(n), where n is the number of vertices in G. The best currently known algorithm guarantees -&-Agrave; (G)-&-equil;O(n/logn). In this paper we present a simple and efficient coloring algorithm which guarantees -&-Agrave;(G)-&-le;x(G)n (equation), a considerable improvem-&-edot;nt over the current bounds.
