An Adaptive Chebyshev Iterative Method
Mathematical Models and Computer Simulations, 2018The authors construct an adaptive iterative method of Chebyshev type in order to solve large systems of linear algebraic equations. These systems appear by applying some multigrid methods to 3D linear and self-adjoint elliptic boundary value problems. The algebraic systems inherit the properties of the problems.

Padé iteration method for regularization
Applied Mathematics and Computation, 2006For the linear operator equation \(Kx=y\) with a compact operator \(K\) acting on an infinite dimensional Hilbert space iterative regularization methods of the form \[ x_{i+1}=(I-\omega T^{-1}K^*K)x_i+\omega K^*y, \quad i=0,1,2,..., \] are considered.

Analysis of Iterative Methods in Photoacoustic Tomography with Variable Sound Speed
SIAM Journal of Imaging Sciences, 2016In this article, we revisit iterative methods for solving the inverse source problem of photoacoustic tomography in free space. Recently, there have been interesting developments on explicit formulations of the adjoint operator, demonstrating that ...

Iterative Reasoning Preference Optimization
Neural Information Processing SystemsIterative preference optimization methods have recently been shown to perform well for general instruction tuning tasks, but typically make little improvement on reasoning tasks (Yuan et al., 2024, Chen et al., 2024). In this work we develop an iterative

Asynchronous Iterative Methods for Multiprocessors
Journal of the ACM, 1978Abstract : A class of asynchronous iterative methods is presented for solving a system of equations. Existing iterative methods are identified in terms of asynchronous iterations, and new schemes are introduced corresponding to a parallel implementation on a multiprocessor system with no synchronization between cooperating processes.

One of the problems which arise from the increasing use of multiprocessing is the efficient utilization of all the processors. If the solution of a problem requires T units of time when only one processor is used, it is hoped that using k processor will require only T/k units of time.
