Suppose that K is a nonempty closed convex subset of a complete CAT(0) space X with the nearest point projection P from X onto K. Let T : K → X be a nonexpansive nonself mapping with F(T) := {x ∈ K : Tx = x} ≠ ∅. Suppose that {xn} is generated iteratively by x1 ∈ K, xn+1 = P((1 - αn)xn ⊕ αnTP[(1 - β...
