Unified Convergence Criteria of Derivative-Free Iterative Methods for Solving Nonlinear Equations

open access: yesComputation, 2023
A local and semi-local convergence is developed of a class of iterative methods without derivatives for solving nonlinear Banach space valued operator equations under the classical Lipschitz conditions for first-order divided differences.

Extended convergence analysis of Newton-Potra solver for equations

open access: yesJournal of Numerical Analysis and Approximation Theory, 2020
In the paper a local and a semi-local convergence of combined iterative process for solving nonlinear operator equations is investigated. This solver is built based on Newton solver and has R-convergence order 1.839....

A decorated tree approach to random permutations in substitution-closed classes [PDF]

open access: yes, 2020
We establish a novel bijective encoding that represents permutations as forests of decorated (or enriched) trees. This allows us to prove local convergence of uniform random permutations from substitution-closed classes satisfying a criticality ...

Two Point Iterative Schemes for Nondifferentiable Equations in Banach Space

open access: yesEuropean Journal of Mathematical Analysis, 2023
The local as well as the semi-local convergence analysis is established for a certain single step-two point iterative scheme defined on a Banach space setting. These schemes converge to a locally unique solution of a nonlinear equation.

Extending the Domain with Application of Four-Step Nonlinear Scheme with Average Lipschitz Conditions

open access: yesMathematics, 2023
A novel local and semi-local convergence theorem for the four-step nonlinear scheme is presented. Earlier studies on local convergence were conducted without particular assumption on Lipschitz constant.

Local Comparison between Two Ninth Convergence Order Algorithms for Equations

open access: yesAlgorithms, 2020
A local convergence comparison is presented between two ninth order algorithms for solving nonlinear equations. In earlier studies derivatives not appearing on the algorithms up to the 10th order were utilized to show convergence.

A Comparison Study of the Classical and Modern Results of Semi-Local Convergence of Newton–Kantorovich Iterations-II

open access: yesMathematics, 2022
This article is an independently written continuation of an earlier study with the same title [Mathematics, 2022, 10, 1225] on the Newton Process (NP). This process is applied to solve nonlinear equations. The complementing features are: the smallness of

Unified Convergence Analysis of Two-Step Iterative Methods for Solving Equations

open access: yesEuropean Journal of Mathematical Analysis, 2021
In this paper we consider unified convergence analysis of two-step iterative methods for solving equations in the Banach space setting. The convergence order four was shown using Taylor expansions requiring the existence of the fifth derivative not on ...

Three-Step Derivative-Free Method of Order Six

open access: yesFoundations, 2023
Derivative-free iterative methods are useful to approximate the numerical solutions when the given function lacks explicit derivative information or when the derivatives are too expensive to compute.
