From decomposition method for operators, we consider Newton-like
iterative processes for approximating solutions of nonlinear operators
in Banach spaces. These iterative processes maintain the quadratic
convergence of Newton's method. Since the operator decomposition method
has its highest degree of application in non-differentiable situations,
we construct Newton-type methods using symmetric divided differences,
which allow us to improve the accessibility of the methods.
Experimentally, by studying the basins of attraction of these methods,
observe an improvement in the accessibility of derivative-free iterative
processes that are normally used in these non-differentiable situations,
such as the classic Steffensen's method. In addition, we study both the
local and semi-local convergence of the Newton-type methods considered.
