Optimized first-order methods for smooth convex minimization
Donghwan Kim, Jeffrey A. Fessler
We introduce new optimized first-order methods for smooth unconstrained convex minimization. Drori and Teboulle recently described a numerical method for computing the -iteratio…

Fast X-ray CT image reconstruction using the linearized augmented Lagrangian method with ordered subsets
Hung Nien, Jeffrey A. Fessler
The augmented Lagrangian (AL) method that solves convex optimization problems with linear constraints has drawn more attention recently in imaging applications due to its decomposa…

A convergence proof of the split Bregman method for regularized least-squares problems
Hung Nien, Jeffrey A. Fessler
The split Bregman (SB) method [T. Goldstein and S. Osher, SIAM J. Imaging Sci., 2 (2009), pp. 323-43] is a fast splitting-based algorithm that solves image reconstruction problems…
