度量空间的可靠生成子

Reliable Spanners for Metric Spaces

Sariel Har-Peled, Manor Mendel, Dániel Oláh

摘要:

如果一个网络能够承受网络中的大规模灾难性故障,那么它就是可靠的。更准确地说,某些节点的任何失效都只能在剩余图中造成较小的膨胀破坏,即剩余图中几乎所有节点都保持了可伸缩性。在低维欧几里德环境中,已知近似线性大小的可靠空间的构造。在这里,我们提出了平面图,树和(一般)度量空间的可靠空间的新结构。

英文摘要:

A spanner is reliable if it can withstand large, catastrophic failures in the network. More precisely, any failure of some nodes can only cause a small damage in the remaining graph in terms of the dilation, that is, the spanner property is maintained for almost all nodes in the residual graph. Constructions of reliable spanners of near linear size are known in the low-dimensional Euclidean settings. Here, we present new constructions of reliable spanners for planar graphs, trees and (general) metric spaces.
