... of identifying codes. Identifying codes and locating-dominating codes have been extensively studied: see the Internet bibliography [11] maintained by Antoine Lobstein. For results on the triangular grid, ... ✉Figure 1: A strongly identifying code with density 6/19. The purpose of this note is to prove that this code is optimal, i.e., the density of every strongly identifying code in the in nite triangular ... called a strongly identifying co de. The smallest possible density of a strongly identifying code in the in nite triangular grid is shown to be 6/19.Keywords: Graph, identifying code, triangular...

By applying the result in Theorem 1.1 , we can obtain the minimum dimension of mensuring exact reconstruction of K-sparse signal using the OMP algorithm. Sp ecifically, pluggingǫ =√K −1/(√K ... to the proof of our main theorem. Our proof is in essence based on the mathematicalinduction; First, we show that the index t1found at the first iteration is correct (t1∈ T) under (4) and thenwe...
