....work. The problem of finding efficient edge colorings of a graph has been a subject of active research over the last three decades. Numerous papers have 3 been published on this topic ranging from optimal sequential algorithms to randomized distributed algorithms. We refer the reader to [14, 12, 22, 6, 16, 17, 7, 11] and the references therein. We note that the given a graph with maximum degree Delta, several sequential algorithms can provide solutions that color the graph using no more than Delta 1 colors. In contrast, obtaining such tight bounds in NC or under the distributed computing model is still an ....

....relies on large deviation inequalities that cease to give strong enough bounds for lower values of Delta. The probabilistic analysis makes use of a powerful generalization of Azuma s inequality, described and commented upon in Section 3, that is very well suited for the analysis of algorithms [8, 10, 6, 7]. Although we stated our result in its most general form, for brevity s sake, we shall actually present a slightly weaker version. Namely, we shall show that the above statement holds with the running time replaced by O(k log n) 2 Preliminaries We shall make use of the following definitions, ....

Assume we have a probability space generated by independent random variables X i (choices) where choice X i is from the finite set A i , and a function Y = f(X 1 ; X n ) ....
