Non-cascade random walks in solid-state high harmonic generation [PDF]

open access: yesNature Communications
Random walks—both classical and quantum—unlocked new possibilities in search algorithms and information processing. Although linear photonic systems, with flexible tunability and multiple degrees of freedom, have served as efficient carriers for random ...

On Generalized Random Railways [PDF]

open access: yesCombinatorics, Probability and Computing, 2004
We consider a random generalized railway defined as a random 3-regular multigraph where some vertices are regarded as switches that only allow traffic between certain pairs of attached edges. It is shown that the probability that the generalized railway is functioning is linear in the proportion of switches.

Some simple varieties of trees arising in permutation analysis [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
After extending classical results on simple varieties of trees to trees counted by their number of leaves, we describe a filtration of the set of permutations based on their strong interval trees.

Accessible and Deterministic Automata: Enumeration and Boltzmann Samplers [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
We present a bijection between the set $\mathcal{A}_n$ of deterministic and accessible automata with $n$ states on a $k$-letters alphabet and some diagrams, which can themselves be represented as partitions of the set $[\![ 1..(kn+1) ]\!]$ into $n$ non ...

Modelling Bimodal Data Using a Multivariate Triangular-Linked Distribution

open access: yesMathematics, 2022
Bimodal distributions have rarely been studied although they appear frequently in datasets. We develop a novel bimodal distribution based on the triangular distribution and then expand it to the multivariate case using a Gaussian copula. To determine the

HIGHER RANDOMNESS AND GENERICITY [PDF]

open access: yesForum of Mathematics, Sigma, 2017
We use concepts of continuous higher randomness, developed in Bienvenuet al.[‘Continuous higher randomness’, J. Math. Log. 17(1) (2017).], to investigate$\unicode[STIX]{x1D6F1}_{1}^{1}$-randomness. We discuss lowness for$\unicode[STIX]{x1D6F1}_{1}^{1}$-randomness, cupping with$\unicode[STIX]{x1D6F1}_{1}^{1}$-random sequences, and an analogue of the ...

Object grammars and random generation [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 1998
This paper presents a new systematic approach for the uniform random generation of combinatorial objects. The method is based on the notion of object grammars which give recursive descriptions of objects and generalize context-freegrammars.

Boltzmann Oracle for Combinatorial Systems [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
Boltzmann random generation applies to well-defined systems of recursive combinatorial equations. It relies on oracles giving values of the enumeration generating series inside their disk of convergence.

Combinatorial specification of permutation classes [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
This article presents a methodology that automatically derives a combinatorial specification for the permutation class $\mathcal{C} = Av(B)$, given its basis $B$ of excluded patterns and the set of simple permutations in $\mathcal{C}$, when these sets ...

Generation S-box and P-layer For PRESENT Algorithm Based On 6D Hyper Chaotic System

open access: yesAl-Kitab Journal for Pure Sciences, 2023
In the era of data-driven applications and resource-constrained devices, the need for lightweight algorithms has become increasingly important. Lightweight algorithms refer to computational techniques that strike a balance between efficiency and ...
