论文摘要
我们介绍了一个新的图形问题,即令牌删除游戏,并展示了如何在分布式设置中有效地解决它。我们使用令牌删除游戏作为一种工具,以设计有效的分布式算法,以实现稳定的方向,更通常用于本地最佳的半匹配。 Czygrinow等人的先前工作。 (DISC 2012)在$ O(δ^5)$ $ graphs $δ$的图中找到了稳定的方向,而我们将其提高到$ O(δ^4)$,并且也证明了$ω(δ)$的下限。
We introduce a new graph problem, the token dropping game, and we show how to solve it efficiently in a distributed setting. We use the token dropping game as a tool to design an efficient distributed algorithm for stable orientations and more generally for locally optimal semi-matchings. The prior work by Czygrinow et al. (DISC 2012) finds a stable orientation in $O(Δ^5)$ rounds in graphs of maximum degree $Δ$, while we improve it to $O(Δ^4)$ and also prove a lower bound of $Ω(Δ)$.
