Published in 2022 at "Optimization Letters"

DOI: 10.1007/s11590-021-01753-w

Abstract: In this paper, the convergence of the fundamental alternating minimization is established for non-smooth non-strongly convex optimization problems in Banach spaces, and novel rates of convergence are provided. As objective function a composition of a… read more here.

Published in 2019 at "IEEE Access"

DOI: 10.1109/access.2019.2944173

Abstract: In this paper, we propose a new high-order total variation regularized model with box constraint for image compressive sensing reconstruction. Because of the separable structure of this model, we can easily decompose into three subproblems… read more here.

Published in 2017 at "IEEE Transactions on Automatic Control"

DOI: 10.1109/tac.2016.2561407

Abstract: In this technical note, the fast alternating minimization algorithm (FAMA) is proposed to solve model predictive control (MPC) problems with polytopic and second-order cone constraints. Two splitting strategies with efficient implementations for MPC problems are… read more here.

Published in 2019 at "IEEE Transactions on Automatic Control"

DOI: 10.1109/tac.2018.2872203

Abstract: We propose a Newton-type alternating minimization algorithm (NAMA) for solving structured nonsmooth convex optimization problems where the sum of two functions is to be minimized, one being strongly convex and the other composed with a… read more here.

Published in 2022 at "IEEE transactions on neural networks and learning systems"

DOI: 10.1109/tnnls.2022.3165627

Abstract: In this article, we propose a novel solution for nonconvex problems of multiple variables, especially for those typically solved by an alternating minimization (AM) strategy that splits the original optimization problem into a set of… read more here.
