Let X be a real Banach space with a normalized duality mapping uniformly norm-to-weak⋆ continuous on bounded sets or a reflexive Banach space which admits a weakly continuous duality mapping JΦJΦ with gauge ϕ. Let f be an α-contraction and {Tn}{Tn} a sequence of nonexpansive mappings, we study the strong convergence of explicit iterative schemesequation(1)xn+1=αnf(xn)+(1−αn)Tnxnxn+1=αnf(xn)+(1−αn)Tnxn with a general theorem and then recover and improve some specific cases studied in the literature [K.
