论文摘要

我们提供了第一个确定性数据结构,该数据结构给出了插入边缘插入的加权无方向的图,每个更新都带有polyrogarithmic amortized更新时间和答案查询当前图中任何一对顶点之间的距离,并带有$ o(\ log \ log \ log \ log \ log n)$时间。 在这项工作之前,对于部分动态图,即进行边缘插入或删除的图形不知道数据结构,即使允许对遗忘的对手进行随机化或仅考虑单个源差异,却不在$ n^{o(1)} $更新时间。

We provide the first deterministic data structure that given a weighted undirected graph undergoing edge insertions, processes each update with polylogarithmic amortized update time and answers queries for the distance between any pair of vertices in the current graph with a polylogarithmic approximation in $O(\log \log n)$ time. Prior to this work, no data structure was known for partially dynamic graphs, i.e., graphs undergoing either edge insertions or deletions, with less than $n^{o(1)}$ update time except for dense graphs, even when allowing randomization against oblivious adversaries or considering only single-source distances.
