The r ‐acyclic edge chromatic number of a graph is defined to be the minimum number of colors required to produce an edge coloring of the graph such that adjacent edges receive different colors and every cycle C has at least min(| C |, r ) colors. We show that ( r − 2) d is asymptotically almost surely (a.a.s.) an upper bound on the r ‐acyclic edge chromatic number of a random d ‐regular graph, for all constants r ≥ 4 and d ≥ 2. © 2006 Wiley Periodicals, Inc.
