On the Global and Linear Convergence of the Generalized Alternating Direction Method of Multipliers
The formulation min x,y f(x) + g(y), subject to Ax + By = b, where f and g are extended-value convex functions, arises in many application areas such as signal processing, imaging ...

On the Proximal Jacobian Decomposition of ALM for Multiple-Block Separable Convex Minimization Problems and Its Relationship to
The augmented Lagrangian method (ALM) is a benchmark for solving convex minimization problems with linear constraints. When the objective function of the model under consideration ...
