A New Hybrid Approach for Solving Large-scale Monotone Nonlinear Equations

open access: yesJournal of Mathematical and Fundamental Sciences, 2020
In this paper, a new hybrid conjugate gradient method for solving monotone nonlinear equations is introduced. The scheme is a combination of the Fletcher-Reeves (FR) and Polak-Ribiére-Polyak (PRP) conjugate gradient methods with the Solodov and Svaiter ...

A Projection Hestenes–Stiefel Method with Spectral Parameter for Nonlinear Monotone Equations and Signal Processing

open access: yesMathematical and Computational Applications, 2020
A number of practical problems in science and engineering can be converted into a system of nonlinear equations and therefore, it is imperative to develop efficient methods for solving such equations.

A Practical Approach for Optimal Power Distribution Among the West-to-East Power Transmission Channels with Minimized Losses

open access: yesZhongguo dianli, 2020
In order to reduce the power losses in power transmission from West to East, an optimal power distribution strategy with minimized losses is studied for the West-to-East power transmission channels based on both theoretical analysis and simulation ...

Group Search on the Line [PDF]

open access: yes, 2015
In this paper we consider the group search problem, or evacu- ation problem, in which k mobile entities (\({\cal M}{\cal E}\)s) located on the line perform search for a specific destination. The \({\cal M}{\cal E}\)s are initially placed at the same origin on the line L and the target is located at an unknown distance d, either to the left or to the ...

Inertial-Based Derivative-Free Method for System of Monotone Nonlinear Equations and Application

open access: yesIEEE Access, 2020
Iterative methods for solving nonlinear problems are of great importance due to their appearance in various areas of applications. In this paper, based on the inertial effect, we propose two projection derivative-free iterative methods for solving system

Genetic Line Search [PDF]

open access: yes, 2001
All unconstrained and many constrained optimization problems involve line searches, i.e. minimizing the value of a certain function along a properly chosen direction. There are several methods for performing such one-dimensional optimization but all of them require that the function be unimodal along the search interval. That may force small step sizes

Line Search for Convex Minimization

open access: yesCoRR, 2023
Golden-section search and bisection search are the two main principled algorithms for 1d minimization of quasiconvex (unimodal) functions. The first one only uses function queries, while the second one also uses gradient queries. Other algorithms exist under much stronger assumptions, such as Newton's method.

Comparative Analysis of Accelerated Models for Solving Unconstrained Optimization Problems with Application of Khan’s Hybrid Rule

open access: yesMathematics, 2022
In this paper, we follow a chronological development of gradient descent methods and its accelerated variants later on. We specifically emphasise some contemporary approaches within this research field. Accordingly, a constructive overview over the class

A new conjugate gradient method for acceleration of gradient descent algorithms

open access: yesMoroccan Journal of Pure and Applied Analysis, 2021
An accelerated of the steepest descent method for solving unconstrained optimization problems is presented. which propose a fundamentally different conjugate gradient method, in which the well-known parameter βk is computed by an new formula.
