Title
Optimal bounds on codes for location in circulant graphs.
Abstract
Identifying and locating-dominating codes have been studied widely in circulant graphs of type \(C_{n}(1,2,3,\dots , r)\) over the recent years. In 2013, Ghebleh and Niepel studied locating-dominating and identifying codes in the circulant graphs \(C_{n}(1,d)\) for \(d = 3\) and proposed as an open question the case of \(d > 3\). In this paper we study identifying, locating-dominating and self-identifying codes in the graphs \(C_{n}(1,d)\), \(C_{n}(1,d-1,d)\) and \(C_{n}(1,d-1,d,d + 1)\). We give a new method to study lower bounds for these three codes in the circulant graphs using suitable grids. Moreover, we show that these bounds are attained for infinitely many parameters n and d. In addition, new approaches are provided which give the exact values for the optimal self-identifying codes in \(C_{n}(1,3)\) and \(C_{n}(1,4)\).
