分布式$(Delta + 1)$ - 着色问题是分布式算法中最根本和研究的问题之一。从1986年Cole和Vishkin的工作开始,已经发表了一系列逐渐改进的算法。由于Kuhn和Wattenhofer,我们工作之前的最新运行时间是$ O(Delta Log Delta + Log^* n)$计算,丹佛,CO,2006年,第7--15页。海上[$ 28 $ th $ th年度IEEE计算机科学基础研讨会,加利福尼亚州洛杉矶,1987年,第331---335页]证明了$ frac {1} {2} {2} log^* n $的下限这个问题以及Szegedy和Vishwanathan [第25届年度ACM计算理论研讨会论文集,加利福尼亚州圣地亚哥,加利福尼亚,1993年,pp。 201-207]提供了一个启发式论点,该论点表明,来自本地迭代算法的算法不太可能达到小于$ theta(Delta Log Delta)$的运行时间。我们提出了一个...
The distributed $(Delta + 1)$-coloring problem is one of the most fundamental and well-studied problems in distributed algorithms. Starting with the work of Cole and Vishkin in 1986, a long line of gradually improving algorithms has been published. The state-of-the-art running time, prior to our work, is $O(Delta log Delta + log^* n)$, due to Kuhn and Wattenhofer [Proceedings of the $25$th Annual ACM Symposium on Principles of Distributed Computing, Denver, CO, 2006, pp. 7--15]. Linial [Proceedings of the $28$th Annual IEEE Symposium on Foundation of Computer Science, Los Angeles, CA, 1987, pp. 331--335] proved a lower bound of $frac{1}{2} log^* n$ for the problem, and Szegedy and Vishwanathan [Proceedings of the 25th Annual ACM Symposium on Theory of Computing, San Diego, CA, 1993, pp. 201--207] provided a heuristic argument that shows that algorithms from a wide family of locally iterative algorithms are unlikely to achieve a running time smaller than $Theta(Delta log Delta)$. We present a de...
