Identifying Codes on Directed De Bruijn Graphs
Abstract
For a directed graph G, a t-identifying code is a subset S reflex subset contained in V (G) with the property that for each vertex v a member V (G) the set of vertices of S reachable from v by a directed path of length at most t is both non-empty and unique. A graph is called t-identifiable if there exists a t-identifying code. This paper shows that the directed de Bruijn graph B(d, n) is t-identifiable for n is greater than or equal to 2t1, and is not t-identifiable for n is less than or equal to 2t2.
