WebJun 28, 2012 · We propose a variable metric forward–backward splitting algorithm and prove its convergence in real Hilbert spaces. We then use this framework to derive primal-dual splitting algorithms for solving various classes of monotone inclusions in duality. Some of these algorithms are new even when specialized to the fixed metric case.
WebAug 10, 2024 · We propose a novel variation of the forward--backward splitting method for solving structured monotone inclusions that incorporates past iterates as well as two deviation vectors into the update equations. The deviation vectors bring a great flexibility to the algorithm and can be chosen arbitrarily as long as they jointly satisfy a norm condition. election tower powder trousersWebForward-backward splitting methods are versatile in offering ways of exploiting the special structure of variational inequality problems.
