On the local convergence of the Modified Newton method

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2019
The aim of this paper is to investigate the local convergence of the Modified Newton method, i.e. the classical Newton method in which the first derivative is re-evaluated periodically after m steps. The convergence order is shown to be m + 1.

A MODIFIED INEXACT NEWTON METHOD

open access: yesJournal of applied mathematics & informatics, 2015
In this paper, we consider a modified inexact Newton method for solving a nonlinear system F(x) = 0 where F(x) : R n → R n . The basic idea is to accelerate convergence. A semi-local convergence theorem for the modified inexact Newton method is established and an affineinvariant version is also given.
