For a monotone operator , we shall show
weak convergence of Rockafellar's proximal point algorithm to some
zero of and strong convergence of the perturbed version of Rockafellar's
to under some relaxed conditions, where is the metric projection from onto . Moreover, our proof techniques are simpler than some existed results.
