Longest common subsequence with gap constraints
We consider the longest common subsequence problem in the context of subsequences
with gap constraints. In particular, following Day et al. 2022, we consider the setting when …

On arch factorization and subword universality for words and compressed words
P Schnoebelen, J Veron - International Conference on Combinatorics on …, 2023 - Springer
Using arch-jumping functions and properties of the arch factorization of words, we propose a
new algorithm for computing the subword circular universality index of words. We also …

Discovering Multi-Dimensional Subsequence Queries from Traces--From Theory to Practice
Subsequence-queries with wildcards and gap-size constraints (swg-queries, for short) are
an expressive model for sequence data, in which queries are described by patterns over an …

Ranking and Unranking k-Subsequence Universal Words
D Adamson - International Conference on Combinatorics on Words, 2023 - Springer
A subsequence of a word w is a word u such that u= w [i 1] w [i 2],⋯ w [i| u|], for some set of
indices 1≤ i 1< i 2<⋯< ik≤| w|. A word w is k-subsequence universal over an alphabet Σ if …

Puzzling over subsequence-query extensions: Disjunction and generalised gaps
A Frochaux, S Kleest-Meißner - arXiv preprint arXiv:2305.08236, 2023 - arxiv.org
A query model for sequence data was introduced in [11] in the form of subsequence-queries
with wildcards and gap-size constraints (swg-queries, for short). These queries consist of a …

Directed regular and context-free languages
We study the problem of deciding whether a given language is directed. A language $ L $
is\emph {directed} if every pair of words in $ L $ have a common (scattered) superword in …

Subsequences With Generalised Gap Constraints: Upper and Lower Complexity Bounds
For two strings u, v over some alphabet A, we investigate the problem of embedding u into w
as a subsequence under the presence of generalised gap constraints. A generalised gap …

-Universality of Regular Languages
D Adamson, P Fleischmann, A Huch, T Koß… - arXiv preprint arXiv …, 2023 - arxiv.org
A subsequence of a word $ w $ is a word $ u $ such that $ u= w [i_1] w [i_2]\dots w [i_ {k}] $,
for some set of indices $1\leq i_1< i_2<\dots< i_k\leq\lvert w\rvert $. A word $ w $ is $ k …

Subsequence Pattern Matching with Segment Number Constraint
This paper is concerned with subsequences that consist of limited numbers of segments. We
call a subsequence\emph {$ f $-segmental} if it is composed of $ f $ factors. More precisely …
