On Identifying Codes in the King Grid that are Robust Against Edge Deletions

چکیده
Assume that G = (V,E) is an undirected graph, and C ⊆ V . For every v ∈ V , we denote Ir(G; v) = {u ∈ C : d(u, v) ≤ r}, where d(u, v) denotes the number of edges on any shortest path from u to v. If all the sets Ir(G; v) for v ∈ V are pairwise different, and none of them is the empty set, the code C is called r-identifying. If C is r-identifying in all graphs G that can be obtained from G by deleting at most t edges, we say that C is robust against t known edge deletions. Codes that are robust against t unknown edge deletions form a related class. We study these two classes of codes in the king grid with the vertex set ZZ where two different vertices are adjacent if their Euclidean distance is at most √ 2.

On identifying codes that are robust against edge changes
Assume that G = (V ,E) is an undirected graph, and C ⊆ V . For every v ∈ V , denote Ir(G; v) = {u ∈ C : d(u, v) ≤ r}, where d(u, v) denotes the number of edges on any shortest path from u to v in G. If all the sets Ir(G; v) for v ∈ V are pairwise different, and none of them is the empty set, the codeC is called r-identifying. Themotivation for identifying codes comes, for instance, from finding...
متن کاملAn improved lower bound for (1, ≤ 2)-identifying codes in the king grid
We call a subset C of vertices of a graph G a (1,≤ l)-identifying code if for all subsets X of vertices with size at most l, the sets {c ∈ C|∃u ∈ X, d(u, c) ≤ 1} are distinct. The concept of identifying codes was introduced in 1998 by Karpovsky, Chakrabarty and Levitin. Identifying codes have been studied in various grids. In particular, it has been shown that there exists a (1,≤ 2)-identifying...

متن کاملDesign of A Single-Phase Transformerless Grid-Connected PV Inverter Considering Reduced Leakage Current and LVRT Grid Codes
A new single-phase transformerless grid-connected PV inverter is presented in this paper. Investigations in transformerless grid-connected PV inverters indicate the existence of the leakage current is directly related to the variable common-mode voltage (CMV), which is presented in detail. On the other hand, in recent years it has become mandatory for the transformerless grid-connected PV inver...
