Function Set Structure Influence onto GPA Efficiency

open access: yesMendel, 2017
The paper discusses the influence of function set structure onto efficiency of GPA (Genetic Programming Algorithms), and hierarchical algorithms like GPA-ES (GPA with Evolutionary Strategy to separate parameter optimization) algorithm efficiency.

Two shared set problems in the light of powers of meromorphic functions [PDF]

open access: yesSurveys in Mathematics and its Applications, 2021
In the paper, we deal the two shared set problems in view of powers of meromorphic functions and find results in the sense of least cardinality. We have also shown the sharpness of our main results.

Strong Integer Additive Set-valued Graphs: A Creative Review [PDF]

open access: yes, 2015
For a non-empty ground set $X$, finite or infinite, the {\em set-valuation} or {\em set-labeling} of a given graph $G$ is an injective function $f:V(G) \to \mathcal{P}(X)$, where $\mathcal{P}(X)$ is the power set of the set $X$. A set-indexer of a graph $

Point Set Denoising Using Bootstrap-Based Radial Basis Function. [PDF]

open access: yesPLoS ONE, 2016
This paper examines the application of a bootstrap test error estimation of radial basis functions, specifically thin-plate spline fitting, in surface smoothing.

Generalised L\"uroth expansions and a family of Minkowski's Question-Mark functions [PDF]

open access: yes, 2014
The Minkowski's Question-Mark function is a singular homeomorphism of the unit interval that maps the set of quadratic surds into the rationals. This function has deserved the attention of several authors since the beginning of the twentieth century ...

On Some Optimization Problems on Permutations

open access: yesКібернетика та комп'ютерні технології, 2022
Numerous studies consider combinatorial optimization problems and their solution methods, since a large number of practical problems are described by means of combinatorial optimization models.

Unbounded Viscosity Solutions of Hybrid Control Systems [PDF]

open access: yes, 2008
We study a hybrid control system in which both discrete and continuous controls are involved. The discrete controls act on the system at a given set interface.

A Four Step Feedback Iteration and Its Applications in Fractals

open access: yesFractal and Fractional, 2022
Fractals play a vital role in modeling the natural environment. The present aim is to investigate the escape criterion to generate specific fractals such as Julia sets, Mandelbrot sets and Multi-corns via F-iteration using complex functions h(z)=zn+c, h ...

Sharp rate of average decay of the Fourier transform of a bounded set [PDF]

open access: yes, 2003
We prove that the spherical mean of the Fourier transform of the characteristic function of a bounded convex set (without any additional assumptions) or a bounded set with a C^{3/2} boundary decays at infinity at the same rate as the Fourier transform of

H\"older differentiability of self-conformal devil's staircases [PDF]

open access: yes, 2013
In this paper we consider the probability distribution function of a Gibbs measure supported on a self-conformal set given by an iterated function system (devil's staircase).
