Intersecting codes and partially identifying codes

open access: yesElectronic Notes in Discrete Mathematics, 2001
Abstract Let τ be a code of length n. Then x is called a descendant of the coalition of codewords a, b, …, ei fxi ∈ {ai, bi…, ei} for i = 1,…, n. We study codes with the following property: any two non intersecting coalitions of a limited size have no common descendant. We present constructions based on linear intersecting codes.

On Codes with the Identifiable Parent Property

open access: yesJournal of Combinatorial Theory, Series A, 1998
Suppose \(C\) is a code of length \(n\) over an alphabet \(Q\) containing \(q\) elements and let \(a\) and \(b\) be any two codewords. Then \(c\) is a decendent of \(a\) and \(b\) if \(c_i\) is in \((a_i,b_i)\), for \(i= 1,2,\dots, n\). The authors are interested in codes \(C\) such that given any decendent \(c\), one of the ``parent'' codewords in \(C\

Error-correcting Identifying Codes

open access: yesCoRR, 2022
Assume that a graph $G$ models a detection system for a facility with a possible "intruder," or a multiprocessor network with a possible malfunctioning processor. We consider the problem of placing (the minimum number of) detectors at a subset of vertices in $G$ to automatically determine if there is an intruder, and if so, its precise location.

Development of Query Strategies to Identify a Histologic Lymphoma Subtype in a Large Linked Database System

open access: yesCancer Informatics, 2007
Background Large linked databases (LLDB) represent a novel resource for cancer outcomes research. However, accurate means of identifying a patient population of interest within these LLDBs can be challenging.

Improved bounds on identifying codes in binary Hamming spaces [PDF]

open access: yes, 2010
Let ℓ, n and r be positive integers. Define Fn={0,1}n. The Hamming distance between words x and y of Fn is denoted by d(x,y). The ball of radius r is defined as Br(X)={y∈Fn∣∃x∈X:d(x,y)≤r}, where X is a subset of Fn.

Polyhedra associated with identifying codes in graphs [PDF]

open access: yes, 2018
International audienceThe identifying code problem is a newly emerging search problem, challenging both from a theoretical and a computational point of view, even for special graphs like bipartite graphs.

On the size of identifying codes in binary hypercubes [PDF]

open access: yes, 2009
In this paper, we consider identifying codes in binary Hamming spaces Fn, i.e., in binary hypercubes. The concept of (r,⩽ℓ)-identifying codes was introduced by Karpovsky, Chakrabarty and Levitin in 1998.

Bounds on r-identifying codes in q-ary Lee space [PDF]

open access: yes, 2021
Identifying codes are used to locate malfunctioning processors in multiprocessor systems. In this paper, we study identifying codes in a $q$-ary hypercube which is used in parallel processing.

A fast method for blindly identifying Reed‐Solomon codes based on matrix analysis

open access: yesIET Communications, 2022
For the identification of Reed‐Solomon (RS) codes, the existing methods need to test the possible codeword length and the primitive polynomials exhaustively. Exhaustive search leads to high computational complexity.
