Abstract

This paper studies the iteration-complexity of new regularized hybrid\nproximal extragradient (HPE)-type methods for solving monotone inclusion\nproblems (MIPs). The new (regularized HPE-type) methods essentially consist of\ninstances of the standard HPE method applied to regularizations of the original\nMIP. It is shown that its pointwise iteration-complexity considerably improves\nthe one of the HPE method while approaches (up to a logarithmic factor) the\nergodic iteration-complexity of the latter method.\n
