解决了2006年提出的一个公开问题,证明了单位球图在有界双倍维数度量下存在轻量有界度(1+ε)-空间,并在该空间模型下设计了一个简单的O(log*n)轮分布式算法,仅利用2跳邻域信息寻找该空间.我们进一步研究了二维欧氏平面上的问题,并提出了一个具有类似性质的结构,它也具有低交性质。最后,我们提供了实验结果,证实了我们的算法的性能。
Resolving an open question from 2006, we prove the existence of light-weight bounded-degree (1+ε)-spanners for unit ball graphs in the metrics of bounded doubling dimension, and we design a simple O(log*n)-round distributed algorithm in the LOCAL model for finding such spanners using only 2-hop neighborhood information. We further study the problem in the two dimensional Euclidean plane and we propose a construction with similar properties that has a low-intersection property as well. Lastly, we provide experimental results that confirm the performance of our algorithms.
