On the Entropy of a Two Step Random Fibonacci Substitution

open access: yesEntropy, 2013
We consider a random generalization of the classical Fibonacci substitution. The substitution we consider is defined as the rule mapping, a → baa and b → ab, with probability , and  → ba, with probability 1 – p for 0 < p < 1, and where the random rule is

Complex martingales and asymptotic enumeration

open access: yesRandom Structures & Algorithms, 2017
AbstractMany enumeration problems in combinatorics, including such fundamental questions as the number of regular graphs, can be expressed as high‐dimensional complex integrals. Motivated by the need for a systematic study of the asymptotic behavior of such integrals, we establish explicit bounds on the exponentials of complex martingales. Those bounds

On the asymptotic enumeration of Cayley graphs [PDF]

open access: yesAnnali di Matematica Pura ed Applicata (1923 -), 2021
AbstractIn this paper, we are interested in the asymptotic enumeration of Cayley graphs. It has previously been shown that almost every Cayley digraph has the smallest possible automorphism group: that is, it is a digraphical regular representation (DRR). In this paper, we approach the corresponding question for undirected Cayley graphs.

Approximate Voronoi cells for lattices, revisited

open access: yesJournal of Mathematical Cryptology, 2020
We revisit the approximate Voronoi cells approach for solving the closest vector problem with preprocessing (CVPP) on high-dimensional lattices, and settle the open problem of Doulgerakis–Laarhoven–De Weger [PQCrypto, 2019] of determining exact ...

Optimized Entanglement Purification [PDF]

open access: yesQuantum, 2019
We investigate novel protocols for entanglement purification of qubit Bell pairs. Employing genetic algorithms for the design of the purification circuit, we obtain shorter circuits achieving higher success rates and better final fidelities than what is ...

Paradigm of nonstochastic approach to system identification

open access: yesМіжнародний науково-технічний журнал "Проблеми керування та інформатики", 2023
The concept of a complex system in this work is understood as a large set of dynamic interconnected systems, the exact mathematical model of which is not known or has a very large dimension. In such situation the use of standard methods for synthesizing

On the enumeration and asymptotic growth of free quasigroup words [PDF]

open access: yesInternational Journal of Algebra and Computation, 2020
This paper counts the number of reduced quasigroup words of a particular length in a certain number of generators. Taking account of the relationship with the Catalan numbers, counting words in a free magma, we introduce the term peri-Catalan number for the free quasigroup word counts.

Asymptotic properties of some minor-closed classes of graphs (conference version) [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
Let $\mathcal{A}$ be a minor-closed class of labelled graphs, and let $G_n$ be a random graph sampled uniformly from the set of n-vertex graphs of $\mathcal{A}$. When $n$ is large, what is the probability that $G_n$ is connected? How many components does

Enumeration and Asymptotic Properties of Unlabeled Outerplanar Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2007
We determine the exact and asymptotic number of unlabeled outerplanar graphs. The exact number $g_{n}$ of unlabeled outerplanar graphs on $n$ vertices can be computed in polynomial time, and $g_{n}$ is asymptotically $g\, n^{-5/2}\rho^{-n}$, where $g\approx0.00909941$ and $\rho^{-1}\approx7.50360$ can be approximated. Using our enumerative results we
