Balanced Augmented Lagrangian Method for Convex Programming
We consider the convex minimization model with both linear equality and inequality constraints, and reshape the classic augmented Lagrangian method (ALM) by balancing its subproblems. As a result, one of its subproblems decouples the objective function and the coefficient matrix without any extra condition, and the other subproblem becomes a positive ...

ABSTRACT Crystal plasticity simulations offer insights into the anisotropic deformation of polycrystalline materials such as metals and alloys. However, rate‐independent crystal plasticity models encounter the Taylor ambiguity, where the active slip systems and plastic slip magnitudes are not uniquely defined, posing well‐known numerical challenges [1].

An augmented lagrangian method for sparse SAR imaging [PDF]
In this paper, we present a solution to the constrained l1-norm minimization problem for sparse SAR imaging. The technique we present relies on recent advances in the solution of optimization problems, based on Augmented Lagrangian Methods (ALMs), namely

ABSTRACT Quantifying where marine organisms are born and subsequently disperse to is essential for fisheries management. Here, we conducted Lagrangian particle tracking of viviparous rockfish (Sebastes spp.) collected in the Southern California Bight over the course of 16 years.

This study focuses on the development of a new method, compatible with a clinical routine, for generating pre‐surgery patient‐specific Finite Element (FE) meshes from a reference mesh, as faithful as possible to the anatomy, including soft tissues (skin, hypodermis, muscles) as well as bony structures (mandible and maxilla).

A First-order Augmented Lagrangian Method for Compressed Sensing
We propose a first-order augmented Lagrangian algorithm (FAL) for solving the basis pursuit problem. FAL computes a solution to this problem by inexactly solving a sequence of L1-regularized least squares sub-problems. These sub-problems are solved using
