Richardson and Chebyshev Iterative Methods by Using G-frames

open access: yesSahand Communications in Mathematical Analysis, 2019
In this paper, we design some iterative schemes for solving operator equation $ Lu=f $, where $ L:Hrightarrow H $ is a bounded, invertible and self-adjoint operator on a separable Hilbert space $ H $. In this concern,  Richardson and Chebyshev iterative methods are two outstanding as well as long-standing ones. They can be implemented in different ways

Using Chebyshev’s polynomials for solving Fredholm integral equations of the second kind

open access: yesMathematical Modelling and Analysis
The main problem with the Newton method is the computation of the inverse of the first derivative of the operator involved at each iteration step. Thus, when we want to apply the Newton method directly to solve an integral equation, the existence of the

Bulbs of Period Two in the Family of Chebyshev-Halley Iterative Methods on Quadratic Polynomials

open access: yesAbstract and Applied Analysis, 2013
The parameter space associated to the parametric family of Chebyshev-Halley on quadratic polynomials shows a dynamical richness worthy of study. This analysis has been initiated by the authors in previous works. Every value of the parameter belonging to the same connected component of the parameter space gives rise to similar dynamical behavior.

ON SURFACE FRACTURE OF RAIL HEADS

open access: yesNauka ta progres transportu, 2017
Purpose. The formation of crack-like defects in rails of railway tracks is a serious problem for engineering practice because of the danger of creating emergency situations.

Hybrid chaos-based particle swarm optimization-ant colony optimization algorithm with asynchronous pheromone updating strategy for path planning of landfill inspection robots

open access: yesInternational Journal of Advanced Robotic Systems, 2019
Robots are coming to help us in different harsh environments such as deep sea or coal mine. Waste landfill is the place like these with casualty risk, gas poisoning, and explosion hazards.

Polynomial Tensor Sketch for Element-wise Function of Low-Rank Matrix [PDF]

open access: yes, 1982
This paper studies how to sketch element-wise functions of low-rank matrices. Formally, given low-rank matrix A = [Aij] and scalar non-linear function f, we aim for finding an approximated low-rank representation of the (possibly high-rank) matrix [f(Aij)

The convergence of inexact Chebyshev and Richardson iterative methods for solving linear systems

open access: yesNumerische Mathematik, 1988
Zur Lösung von \(Ax=b\) wird A gemäß \(A=M-N\) aufgespalten. Unter der Voraussetzung, daß \(M^{-1}A\) diagonalähnlich ist wird vorausgesetzt, daß das Spektrum von \(M^{-1}A\) in der rechten Halbebene liegt und sich in einer zur reellen Achse symmetrischen Ellipse befindet.

Consensus acceleration in multi-agent systems with the Chebyshev semi-iterative method

open access: yes, 2011
We consider the fundamental problem of reaching consensus in multiagent systems. To date, the consensus problem has been typically solved with decentralized algorithms based on graph Laplacians. However, the convergence of these algorithms is often too slow for many important multiagent applications, and thus they are increasingly being combined with ...
