“…However, It is known that the Mann iterative algorithm only has weak convergence, even for nonexpansive mappings in infinite-dimensional Hilbert spaces; for more details, see [24,31] and the reference therein. To obtain the strong convergence of the Mann iterative algorithm so-called hybrid projection algorithms have been considered; for more details, see [1,11,12,15,16,17,28,29,40,41,42] and the references therein.…”
