V-order is a total order on strings that determines an instance of Unique Maximal Factorization Families (UMFFs), a generalization of Lyndon words. The fundamental V-comparison of strings can be done in linear time and constant space. V-order has bee

A string X = X [ 1 . . n ] , n > 1 , is said to be closed if it has a nonempty proper prefix that is also a suffix, but that otherwise occurs nowhere else in X ; for n = 1 , every X is closed. Closed strings were introduced by Fici in [1] as objects

Data analytics may conveniently be divided into four stages: preparation, preprocessing, analysis, and post-processing. Especially in the second and third of these, where the data is cleaned, filtered and analyzed, string processing algorithms are fu
In this paper we propose a new, more appropriate definition of regular and indeterminate strings. A regular string is one that is "isomorphic" to a string whose entries all consist of a single letter, but which nevertheless may itself include entries

We study a central problem of string processing: the compact representation of a string by its frequently-occurring substrings. In this paper we propose an effective, easily-computed form of quasi-periodicity in strings, the frequency cover; that is,

In this paper we introduce the notion of an optimal cover. Let M denote the maximum number of positions in w covered by any repeating substring of w . Then a longest (shortest) optimal cover u is a longest (shortest) repeating substring of w that cov

As discussed at length in Christodoulakis et al. (2015) [3] , there is a natural one-many correspondence between simple undirected graphs G with vertex set V = { 1 , 2 , … , n } and indeterminate strings x = x [ 1 . . n ] — that is, sequences of

Given a string x = x [ 1 . . n ] on an ordered alphabet Σ of size σ, the Lyndon array λ = λ x [ 1 . . n ] of x is an array of positive integers such that λ [ i ] , 1 ≤ i ≤ n , is the length of the maximal Lyndon word over the ordering of Σ

A parameterized string (p-string) is a generalization of the traditional string over two alphabets: a constant alphabet and a parameter alphabet. A parameterized match (p-match) exists between two p-strings if the constants match exactly and if there

The prefix array was apparently first computed and used algorithmically in 1984, playing a pivotal role in an optimal algorithm to determine all the tandem repeats in a given (DNA or protein) sequence. However, it is especially since the turn of the
