无限王格上的容错定位-支配集

Fault-tolerant Locating-Dominating Sets on the Infinite King Grid

Devin Jean, Suk Seo

AI总结:

本文研究了无限王格上三种容错定位-支配集(冗余、错误检测和错误纠正),确定了其最小密度的上下界。

摘要:

设 $G$ 为网络系统的图,顶点 $V(G)$ 表示物理位置,边 $E(G)$ 表示信息连接。\emph{定位-支配(LD)集} $S \subseteq V(G)$ 是表示探测器的顶点子集,能感知“入侵者”恰在其位置或其开邻域内——LD 集必须能定位图中任意处的入侵者。我们探讨三类容错 LD 集:\emph{冗余 LD 集},允许移除一个探测器;\emph{错误检测 LD 集},允许至多一个假阴性;\emph{错误纠正 LD 集},允许至多一个错误(假阳性或假阴性)。特别地,我们确定了这三种容错定位-支配集在 \emph{无限王格} 中最小密度的下界和上界。

英文摘要:

Let $G$ be a graph of a network system with vertices, $V(G)$, representing physical locations and edges, $E(G)$, representing informational connectivity. A \emph{locating-dominating (LD)} set $S \subseteq V(G)$ is a subset of vertices representing detectors capable of sensing an "intruder" at precisely their location or somewhere in their open-neighborhood -- an LD set must be capable of locating an intruder anywhere in the graph. We explore three types of fault-tolerant LD sets: \emph{redundant LD} sets, which allow a detector to be removed, \emph{error-detecting LD} sets, which allow at most one false negative, and \emph{error-correcting LD} sets, which allow at most one error (false positive or negative). In particular, we determine lower and upper bounds for the minimum density of these three fault-tolerant locating-dominating sets in the \emph{infinite king grid}.
