Let C be a nonempty closed convex subset of a complete CAT(0) space X. We define a modified NSP-iteration for a nonexpansive selfmapping T on C as follows: x1∈ C, and for each n ∈ ℕ, (formula presented)The strong and △-convergence of the above iteration scheme under some certain conditions of the sequences {an}, {bn}, {cn}, {αn} and {βn} in [0, 1] are shown. Our results extend and generalize many results in the literature.Mahidol UniversityMathematicsArticleSCOPUS
