A regularized alternating direction method of multipliers for a class of nonconvex problems

open access: yesJournal of Inequalities and Applications, 2019
In this paper, we propose a regularized alternating direction method of multipliers (RADMM) for a class of nonconvex optimization problems. The algorithm does not require the regular term to be strictly convex. Firstly, we prove the global convergence of

Mathematical analysis and numerical methods for pricing pension plans allowing early retirement [PDF]

open access: yes
In this paper, we address the mathematical analysis and numerical solution of a model for pricing a defined benefit pension plan. More precisely, the benefits received by the member of the plan depend on the average salary and early retirement is allowed.

Augmented Lagrangian method for coupled-cluster

open access: yes
We propose to improve the convergence properties of the single-reference coupled cluster (CC) method through an augmented Lagrangian formalism. The conventional CC method changes a linear high-dimensional eigenvalue problem with exponential size into a problem of determining the roots of a nonlinear system of equations that has a manageable size ...

Insight into Primal Augmented Lagrangian Multilplier Method

open access: yes, 2013
We provide a simplified form of Primal Augmented Lagrange Multiplier algorithm. We intend to fill the gap in the steps involved in the mathematical derivations of the algorithm so that an insight into the algorithm is made. The experiment is focused to show the reconstruction done using this algorithm.

Constrained optimization of a zoom lens with CMA-ES algorithm [PDF]

open access: yesEPJ Web of Conferences
In the present paper we investigate how optimization algorithm can be tailored to improve the lens design process. We replaced gradient-based optimization methods by the Covariance Matrix Adaptation Evolution Strategy (CMA-ES).

Frank-Wolfe Splitting via Augmented Lagrangian Method

open access: yes, 2018
Minimizing a function over an intersection of convex sets is an important task in optimization that is often much more challenging than minimizing it over each individual constraint set. While traditional methods such as Frank-Wolfe (FW) or proximal gradient descent assume access to a linear or quadratic oracle on the intersection, splitting techniques

Partial symmetric regularized alternating direction method of multipliers for non-convex split feasibility problems

open access: yesAIMS Mathematics
In this paper, we propose a kind of partial symmetric regularized alternating direction method of multipliers for solving non-convex split feasibility problems. This algorithm adds an update to the Lagrangian multiplier term during the iteration process.
