• A new technique to obtain derivative-free methods with optimal order of convergence in the sense of the Kung�Traub conjecture for solving nonlinear smooth equations is described. The procedure uses Steffensen-like methods and Padé approximants. Some numerical examples are provided to show the good performance of the new methods.
