Three-step iterative methods with optimal eighth-order convergence [PDF]

Journal of Computational and Applied Mathematics, 2011
In this paper, based on Ostrowski’s method, a new family of eighth-order methods for solving nonlinear equations is derived. In terms of computational cost, each iteration of these methods requires three evaluations of the function and one evaluation of ...

Construction of fourth-order optimal families of iterative methods and their dynamics [PDF]

Applied Mathematics and Computation, 2015
[EN] In this paper, we propose a general class of fourth-order optimal multi-point methods without memory for obtaining simple roots. This class requires only three functional evaluations (viz.

An Optimal Three-point Eighth Order Iterative Method for Solving Non-linear Equations and The Attraction basins

Sylwan
In this research study, we have proposed a new eighth-order optimal method. The new method consists of three steps: the Newton step, an optimal fourth-order iteration scheme, and a simply structured third step that improves the convergence order up to at least eight and ensures an efficiency index of 1.682.
