Nonlinear Preconditioning: How to use a Nonlinear Schwarz Method to Precondition Newton's Method [PDF]

open access: yes, 2015
For linear problems, domain decomposition methods can be used directly as iterative solvers, but also as preconditioners for Krylov methods. In practice, Krylov acceleration is almost always used, since the Krylov method finds a much better residual ...

PHSS Iterative Method for Solving Generalized Lyapunov Equations

open access: yesMathematics, 2019
Based on previous research results, we propose a new preprocessing HSS iteration method (PHSS) for the generalized Lyapunov equation. At the same time, the corresponding inexact PHSS algorithm (IPHSS) is given from the angle of application.

The iterative transformation method [PDF]

open access: yesInternational Journal of Non-Linear Mechanics, 2019
In a transformation method, the numerical solution of a given boundary value problem is obtained by solving one or more related initial value problems. Therefore, a transformation method, like a shooting method, is an initial value method. The main difference between a transformation and a shooting method is that the former is conceived and derive its ...

A Modified Ren’s Method with Memory Using a Simple Self-Accelerating Parameter

open access: yesMathematics, 2020
In this paper, a self-accelerating type method is proposed for solving nonlinear equations, which is a modified Ren’s method. A simple way is applied to construct a variable self-accelerating parameter of the new method, which does not increase any ...

Approximate k-space models and Deep Learning for fast photoacoustic reconstruction [PDF]

open access: yes, 2018
We present a framework for accelerated iterative reconstructions using a fast and approximate forward model that is based on k-space methods for photoacoustic tomography. The approximate model introduces aliasing artefacts in the gradient information for

The Four-Parameter PSS Method for Solving the Sylvester Equation

open access: yesMathematics, 2019
In order to solve the Sylvester equations more efficiently, a new four parameters positive and skew-Hermitian splitting (FPPSS) iterative method is proposed in this paper based on the previous research of the positive and skew-Hermitian splitting (PSS ...

Iterative simulation methods

open access: yesJournal of Computational and Applied Mathematics, 1990
AbstractThe standard methods of generating sample from univariate distributions often become hopelessly inefficient when applied to realizations of stochastic processes. Iterative methods are not widely known amongst statisticians, but some are standard practice in statistical physics and chemistry.

An Iterative Method for Moving Target Localization Using TDOA and FDOA Measurements

open access: yesIEEE Access, 2018
For moving targets localization, incorporating frequency-difference-of-arrival (FDOA) measurements in the commonly used time-difference-of-arrival (TDOA) positioning systems will improve performance.
