Basin attractors for derivative-free methods to find simple roots of nonlinear equations

open access: yesJournal of Numerical Analysis and Approximation Theory, 2020
 Many methods exist for solving nonlinear equations. Several of these methods are derivative-free. One of the oldest is the secant method where the derivative is replaced by a divided difference.

Seventh Order Derivative-Free Methods for Non-differentiable Operator Equations

open access: yesEuropean Journal of Mathematical Analysis, 2023
In nonlinear problems where function’s derivatives are difficult or expensive to compute, derivative-free iterative methods are good options to find the numerical solution.

Comparison of some optimal derivative-free three-point iterations

open access: yesJournal of Numerical Analysis and Approximation Theory, 2020
We show that the well-known Khattri et al. methods and Zheng et al. methods are identical. In passing, we propose a suitable calculation formula for Khattri et al. methods.

A New Derivative-Free Method to Solve Nonlinear Equations

open access: yesMathematics, 2021
A new high-order derivative-free method for the solution of a nonlinear equation is developed. The novelty is the use of Traub’s method as a first step. The order is proven and demonstrated.

A derivative-free Gauss–Newton method [PDF]

open access: yesMathematical Programming Computation, 2019
We present DFO-GN, a derivative-free version of the Gauss-Newton method for solving nonlinear least-squares problems. As is common in derivative-free optimization, DFO-GN uses interpolation of function values to build a model of the objective, which is then used within a trust-region framework to give a globally-convergent algorithm requiring $O(ε^{-2})

Derivative-free optimization methods [PDF]

open access: yesActa Numerica, 2019
In many optimization problems arising from scientific, engineering and artificial intelligence applications, objective and constraint functions are available only as the output of a black-box or simulation oracle that does not provide derivative information. Such settings necessitate the use of methods for derivative-free, or zeroth-order, optimization.

Extended Seventh Order Derivative Free Family of Methods for Solving Nonlinear Equations

open access: yesMathematics, 2023
A plethora of applications from Computational Sciences can be identified for a system of nonlinear equations in an abstract space. These equations are mostly solved with an iterative method because an analytical method does not exist for such problems ...

A Derivative-Free Method for Structured Optimization Problems [PDF]

open access: yesSIAM Journal on Optimization, 2021
Structured optimization problems are ubiquitous in fields like data science and engineering. The goal in structured optimization is using a prescribed set of points, called atoms, to build up a solution that minimizes or maximizes a given function. In the present paper, we want to minimize a black-box function over the convex hull of a given set of ...
