Higher-Order Iteration Schemes for Solving Nonlinear Systems of Equations
Mathematics, 2019 We present a three-step family of iterative methods to solve systems of nonlinear equations. This family is a generalization of the well-known fourth-order King’s family to the multidimensional case.

A Novel Method of 3D Multipoint Geostatistical Inversion Using 2D Training Images [PDF]
, 2022 The seismic inversion method combined with multipoint geostatistics theory has begun to receive attention, but the acquisition accuracy and calculation efficiency of 3D training image still need more optimization. This paper presents a novel method of 3D

Solving Variational Inclusions by a Method Obtained Using a Multipoint Iteration Formula
Revista Matemática Complutense, 2009 This paper deals with variational inclusions of the form: 0 e f(x)+F(x) where f is a single function admitting a second order Frechet derivative and F is a set-valued map acting in Banach spaces. We prove the existence of a sequence (x k ) satisfying 0 e f(x k )+∑ M i=1 a i Λf(x k +β i (x k+1 -x k ))(x k+1 -x k )+F(x k+1 ) where the single-valued ...

Fast iterative solvers for PDE-constrained optimization problems [PDF]
, 2013 In this thesis, we develop preconditioned iterative methods for the solution of matrix systems arising from PDE-constrained optimization problems. In order to do this, we exploit saddle point theory, as this is the form of the matrix systems we wish to ...

Multipoint forming using hole-type rubber punch [PDF]
, 2022 Reconfigurable multipoint forming is a flexible sheet forming technique aimed at customised sheet metal products. However, one drawback of multipoint forming is the cost and time needed to set up and align the upper and lower pin matrices.

On multipoint iterative processes of efficiency index higher than Newton's method
Journal of Nonlinear Sciences and Applications, 2009 We provided a convergence analysis of third-order multipoint it- erative processes of eciency index higher than Newton's. Our convergence analysis is finer than the corresponding one in (8), under the same or weaker hypotheses and computational cost.

A Class of Three-Step Derivative-Free Root Solvers with Optimal Convergence Order
Journal of Applied Mathematics, 2012 A class of three-step eighth-order root solvers is constructed in this study. Our aim is fulfilled by using an interpolatory rational function in the third step of a three-step cycle.
