Abstract
In this project, we study the results of Colao and Marino on the paper "krasnosnoslskii-Mann
method for non-self mappings" to approximate fixed points of non-self, non-expansive mappings
in a real Hilbert space with out involving the calculation of a projection or a retraction
mapping. To this end, for a closed, convex and nonempty subset C of a Hilbert space H
and a non-expansive mappings T : C ! H, We introduce a new search strategy for the coefficients

convergence results when C is a strictly convex set and T is an inward mapping. We then
illustrate this results with a brief numerical examples.
