On a Three-Step Efficient Fourth-Order Method for Computing the Numerical Solution of System of Nonlinear Equations and Its Applications Anuradha Singh Proceedings of the National Academy of Sciences India Section A Physical Sciences, 2020 In this paper, a new fourth-order iterative scheme for finding the zeros of systems of nonlinear equations has been built and analyzed. Theoretical proof has been given to confirm the convergence order of the new method. The effectiveness of the proposed method is shown by the comparison of traditional as well as flops-like efficiency index with recent existing same order schemes. Numerical examples confirm that the new iterative method is efficient and gives tough competition to some existing fourth-order methods. We have also discussed the application of our proposed method for finding numerical solution of nonlinear ODE and PDE.

An efficient iterative scheme for computing multiple roots of nonlinear equations Anuradha Singh Proceedings 7th International Conference on Communication Systems and Network Technologies Csnt 2017, 2018 One of the most challenging tasks in real life is to find the multiple zeros of nonlinear equations. It is also known that the iterative methods are highly sensitive towards initial guesses. So, the choice of initial guess is also a difficult task with iterative methods. Various researchers have established the generalized form of iterative methods for finding the multiple roots. The prime focus of this study is to extend existing fourth order method from simple roots to multiple roots because some of the available methods for findings multiple root are fails or do not perform well for some nonlinear functions.

Numerical examples are given to show the performance of the proposed method with some existing schemes. We observed from the comparison of the new scheme with some known methods that the proposed scheme shows high efficiency index than others.

An Efficient Family of Optimal Fourth-Order Iterative Methods for Finding Multiple Roots of Nonlinear Equations Anuradha Singh, J. P. Jaiswal Proceedings of the National Academy of Sciences India Section A Physical Sciences, 2015 In the present paper, we propose a new family of the fourth-order iterative methods for finding multiple root of nonlinear equations with known multiplicity. This family is the multiple extension of the existing family for simple root. Some particular cases of proposed method have been also discussed. The presented iterative family requires one function and two derivative evaluations and thus agree with the conjecture of Kung-Traub for the case $$n = 3$$n=3 (i.e. optimal). Numerical comparisons have been carried out to show the performance of the proposed method. Finally, we compare our method with some existing methods by basin of attractions and observe that the proposed scheme is competitive to other existing methods for obtaining multiple root of nonlinear equations.
Improving R-order convergence of derivative free with memory method by two self-accelerator parameters Anuradha Singh, J. P. Jaiswal Springer Proceedings in Mathematics and Statistics, 2015 The object of the present paper is to improve the R-order convergence of with memory method proposed by Eftekhari (Int J Differ Eqn 2014:6, 2014) [1]. To achieve this goal, one more iterative parameter is introduced, which is calculated with the help of Newton’s interpolatory polynomial of degree five. It is shown that the R-order convergence of the proposed method is increased from 11.2915 to 13.4031 without any extra evaluation. Smooth as well as nonsmooth examples are presented to confirm theoretical result and superiority of the new scheme.
