Ultrasound wave propagation through rough interfaces: Iterative methods [PDF]

open access: yes, 1996
Two iterative methods for the calculation of acoustic transmission through a rough interface\ud between two media are compared. The methods employ a continuous version of the conjugate\ud gradient technique.

Eliminating Iterations of Iterative Methods [PDF]

open access: yesProceedings of the 2021 Great Lakes Symposium on VLSI, 2021
The sparse linear solver is an important component in lots of scientific computing applications. For large-scale sparse linear systems, general-purpose processors such as CPUs and GPUs are facing challenges of high time complexity and massive data movements between processors and main memories. This work utilizes the ability of in-situ analog computing

Free Boundary Formulation for BVPs on a Semi-Infinite Interval and Non-Iterative Transformation Methods [PDF]

open access: yes, 2014
This paper is concerned with two examples on the application of the free boundary formulation to BVPs on a semi-infinite interval. In both cases we are able to provide the exact solution of both the BVP and its free boundary formulation. Therefore, these

On iterative methods for bilevel equilibrium problems

open access: yesJournal of Inequalities and Applications, 2021
We use the notion of Halpern-type sequence recently introduced by the present authors to conclude two strong convergence theorems for solving the bilevel equilibrium problems proposed by Yuying et al. and some authors.

Iterative Methods for Computing Vibrational Spectra

open access: yesMathematics, 2018
I review some computational methods for calculating vibrational spectra. They all use iterative eigensolvers to compute eigenvalues of a Hamiltonian matrix by evaluating matrix-vector products (MVPs). A direct-product basis can be used for molecules with

Extended Convergence of Two Multi-Step Iterative Methods

open access: yesFoundations, 2023
Iterative methods which have high convergence order are crucial in computational mathematics since the iterates produce sequences converging to the root of a non-linear equation. A plethora of applications in chemistry and physics require the solution of

A q-Gradient Descent Algorithm with Quasi-Fejér Convergence for Unconstrained Optimization Problems

open access: yesFractal and Fractional, 2021
We present an algorithm for solving unconstrained optimization problems based on the q-gradient vector. The main idea used in the algorithm construction is the approximation of the classical gradient by a q-gradient vector.

New SOR-like methods for solving the Sylvester equation

open access: yesOpen Mathematics, 2014
We present new iterative methods for solving the Sylvester equation belonging to the class of SOR-like methods, based on the SOR (Successive Over-Relaxation) method for solving linear systems.

Schwarz Iterative Methods: Infinite Space Splittings [PDF]

open access: yes, 2014
We prove the convergence of greedy and randomized versions of Schwarz iterative methods for solving linear elliptic variational problems based on infinite space splittings of a Hilbert space. For the greedy case, we show a squared error decay rate of $O((
