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.

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.

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.

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.

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.

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 ...

Derivative-Free Optimal Iterative Methods

open access: yesComputational Methods in Applied Mathematics, 2010
AbstractIn this study, we develop an optimal family of derivative-free iterative methods. Convergence analysis shows that the methods are fourth order convergent, which is also verified numerically. The methods require three functional evaluations during each iteration. Though the methods are independent of derivatives, computa-

A Note on Traub’s Method for Systems of Nonlinear Equations

open access: yesMathematics, 2021
Traub’s method was extended here to systems of nonlinear equations and compared to Steffensen’s method. Even though Traub’s method is only of order 1.839 and not quadratic, it performed better in the 10 examples.
