DOI: 10.1007/s10589-018-0033-z

Abstract: We develop two new proximal alternating penalty algorithms to solve a wide range class of constrained convex optimization problems. Our approach mainly relies on a novel combination of the classical quadratic penalty, alternating minimization, Nesterov’s… read more here.

Published in 2020 at "Numerical Algorithms"

DOI: 10.1007/s11075-019-00705-x

Abstract: In this paper, we propose an augmented Lagrangian proximal alternating (ALPA) method for solving two classes of large-scale sparse discrete constrained optimization problems. Specifically, the ALPA method generates a sequence of augmented Lagrangian (AL) subproblems… read more here.
