我们引入了新的数据结构来回答受批处理顶点失败影响的图中的连通性查询。确定性结构在时间上处理一批失败的顶点,然后在时间上回答连接查询。它占据空间。我们开发了数据结构的随机蒙特卡罗版本,其中包含任何故障范围的更新时间、查询时间和空间。这是第一个可以有效处理无界顶点故障的通用图连接oracle。我们还开发了一个更高效的Monte Carloedgefailure连接oracle。利用空间,及时处理边缘故障,及时回答连接查询,正确率高。我们的数据结构是基于一个新的无向图分解定理,这是一个独立的兴趣。它表明,对于任何终端集,我们可以删除一个集的顶点,使得剩余的图包含一个最大度的斯坦纳森林。
We introduce new data structures for answering connectivity queries in graphs subject to batchedvertex failures. A deterministic structure processes a batch offailed vertices intime and thereafter answers connectivity queries intime. It occupies space. We develop a randomized Monte Carlo version of our data structure with update time, query time, and spacefor any failure bound. This is the first connectivity oracle for general graphs that can efficiently deal with an unbounded number of vertex failures. We also develop a more efficient Monte Carloedgefailure connectivity oracle. Using space,edge failures are processed intime, and thereafter, connectivity queries are answered intime, which are correct with high probability. Our data structures are based on a new decomposition theorem for an undirected graph, which is of independent interest. It states that for any terminal setwe can remove a setofvertices such that the remaining graph contains a Steiner forest forwith maximum degree.
