In this paper we consider constructing some higher-order modifications of Newton's method for solving nonlinear equations which increase the order of convergence of existing iterative methods by one or two or three units. This construction can be applied to any iteration formula, and per iteration t

✦ Synopsis
In this paper, modifications of a generalized Newton method based on some rules of quadrature are studied. The methods considered are Newton-like iterative schemes for numerical solving systems of nonsmooth equations. Some mild conditions are given that ensure superlinear convergence to a solution. Moreover, a parameterized version of the midpoint version is presented. Finally, results of numerical tests are established.

An interpretation of quasi-Newton methods of solving sets of equations is given, and provides the basis of four versions of the secants method, stable with respect to a linear dependence of the directions of motion. The first version involves an approximation of the matrix of first derivatives (the
