Order of Convergence and Dynamics of Newton–Gauss-Type Methods

open access: yesFractal and Fractional, 2023
On the basis of the new iterative technique designed by Zhongli Liu in 2016 with convergence orders of three and five, an extension to order six can be found in this paper. The study of high-convergence-order iterative methods under weak conditions is of

A Combined Conjugate Gradient Quasi-Newton Method with Modification BFGS Formula

open access: yesInternational Journal of Analysis and Applications, 2023
The conjugate gradient and Quasi-Newton methods have advantages and drawbacks, as although quasi-Newton algorithm has more rapid convergence than conjugate gradient, they require more storage compared to conjugate gradient algorithms.

Solving Nonlinear Transcendental Equations by Iterative Methods with Conformable Derivatives: A General Approach

open access: yesMathematics, 2023
In recent years, some Newton-type schemes with noninteger derivatives have been proposed for solving nonlinear transcendental equations by using fractional derivatives (Caputo and Riemann–Liouville) and conformable derivatives.

Newton-Type Methods for Solution of the Electric Network Equations

open access: yesTrends in Computational and Applied Mathematics, 2002
Electric newtork equations give rise to interesting mathematical models that must be faced with efficient numerical optimization techniques. Here, the classical power flow problem represented by a nonlinear system of equations is solved by inexact Newton

On the Convergence Rate of Quasi-Newton Methods on Strongly Convex Functions with Lipschitz Gradient

open access: yesMathematics, 2023
The main results of the study of the convergence rate of quasi-Newton minimization methods were obtained under the assumption that the method operates in the region of the extremum of the function, where there is a stable quadratic representation of the ...

Reducing Chaos and Bifurcations in Newton-Type Methods

open access: yesAbstract and Applied Analysis, 2013
We study the dynamics of some Newton-type iterative methods when they are applied of polynomials degrees two and three. The methods are free of high-order derivatives which are the main limitation of the classical high-order iterative schemes.

A New Globally Convergent Self-Scaling Vm Algorithm for Convex and Nonconvex Optimization [PDF]

open access: yesKirkuk Journal of Science, 2011
In unconstrained optimization, the original quasi-Newton condition where is the difference of the gradients at two successive iterations. Li and Fukushima proposed a modified BFGS methods based on a new Quasi –Newton equation where , where is a
