Distributed deterministic edge coloring using bounded neighborhood independence
Leonid Barenboim, Michael Elkin · 2011
We study the edge-coloring problem in the message-passing model of distributed computing. This is one of the most fundamental problems in this area. Currently, the best-known deterministic algorithms for (2Δ-1)-edge-coloring requires O(Δ) + log* n time [23], where Δ is the maximum degree of the input graph. Also, recent results of [5] for vertex-coloring imply that one can get an O(Δ)-edge-coloring in O(Δµ" log n) time, and an O(Δ1 + µ)-edge-coloring in O(log Δ log n) time, for an arbitrarily small constant µ > 0.
