Lagrange optimality system for a class of nonsmooth convex optimization [PDF]
, 2015 In this paper, we revisit the augmented Lagrangian method for a class of nonsmooth convex optimization. We present the Lagrange optimality system of the augmented Lagrangian associated with the problems, and establish its connections with the standard ...

A Modified Augmented Lagrange Multiplier Method for Non-Linear Programming [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2013 In this paper, we have investigated a new algorithm which employs an Augmented Lagrangian Method (ALM). It overcomes many of the difficulties associated with the Penalty function method. The new incorporate algorithm has been proved very effective with

Discrete Dynamics in Nature and Society, 2017 We propose a new method for equality constrained optimization based on augmented Lagrangian method. We construct an unconstrained subproblem by adding an adaptive quadratic term to the quadratic model of augmented Lagrangian function.

Parallel MR Image Reconstruction Using Augmented Lagrangian Methods [PDF]
IEEE Transactions on Medical Imaging, 2011 Magnetic resonance image (MRI) reconstruction using SENSitivity Encoding (SENSE) requires regularization to suppress noise and aliasing effects. Edge-preserving and sparsity-based regularization criteria can improve image quality, but they demand computation-intensive nonlinear optimization.
