Abstract. In this paper, we present two new modified Newton methods for solving a non-linear equation, permitting f'(x) = 0 in some points. These new methods are showed to be cubically convergent. From the practical application, we show that these new methods are vast superior and possible in global convergence. Keywords: Newton method; Third-order convergence; Non-linear equations; Root-f…
Abstract. In this paper, we present a new modification of Newton method for solving non-linear equations. Analysis of convergence shows that the new method is cubically convergent. Per iteration the new method requires two evaluations of the function and one evaluation of its first derivative. Thus, the new method is preferable if the computational costs of the first derivative are equal or mo…
Abstract. In this paper, we present a family of new methods with the order of convergence four. Per iteration these methods require two evaluations of the function and one evaluation of its first derivative and therefore this family of methods has the efficiency index equal to 1.587. These methods can be of practical interest, as we show in some examples. Keywords: Newton’s method; Non-l…
