On the Existence of $t$-Identifying Codes in Undirected De Bruijn Graphs
Victoria Horan ;
Date 3 Aug 2015
AbstractThis paper proves the existence of $t$-identifying codes on the class of undirected de Bruijn graphs with string length $n$ and alphabet size $d$, referred to as $mathcal{B}(d,n)$. It is shown that $mathcal{B}(d,n)$ is $t$-identifiable whenever $d geq 3$ and $n geq 2t$, and $t geq 1$. We also show that $mathcal{B}(d,n)$ is $t$-identifiable if either $d geq 3$, $n geq 3$, and $t=2$, or if $d = 2$, $n geq 3$, and $t=1$. The remaining cases remain open. Additionally, we show that the eccentricity of the undirected non-binary de Bruijn graph is $n$.
