We present a deterministic distributed algorithm in the LOCAL model that finds a proper (Δ+1)-edge-coloring of an n-vertex graph of maximum degree Δ in poly(Δ,logn) rounds. This is the first nontrivial distributed edge-coloring algorithm that uses only Δ+1 colors (matching the bound given by Vizing's theorem). Our approach is inspired by the recent proof of the measurable version of Vizing's theorem due to Grebík and Pikhurko.

(Δ+1)-边缘着色的一种快速分布式算法

我们提出了一种确定性分布式算法 当地的 找到合适的模型 (Δ+1)最大度为 Δ的n顶点图的边着色(Δ,日志n)回合。这是第一个仅使用的非平凡分布式边缘着色算法Δ+1颜色(匹配 Vizing 定理给出的界限)。我们的方法的灵感来自于最近由 Grebík 和 Pikhurko 提出的 Vizing 定理的可测量版本的证明。
