A Stochastic Composite Augmented Lagrangian Method For Reinforcement Learning [PDF]

open access: yesSIAM Journal on Optimization, 2021
In this paper, we consider the linear programming (LP) formulation for deep reinforcement learning. The number of the constraints depends on the size of state and action spaces, which makes the problem intractable in large or continuous environments. The

Augmented Lagrangian method for imposing nonlinear multi freedom constraints in static analysis for frames using FEM [PDF]

open access: yesE3S Web of Conferences, 2021
This paper focuses on the treatment of nonlinear multi freedom constraints using an augmented Lagrangian method in finite element analysis of frames. The process of imposing boundary constraints is developed by changing the assembly stiffness equation to

Preconditioned augmented Lagrangian method for mean curvature image deblurring

open access: yesAIMS Mathematics, 2022
Image deblurring models with a mean curvature functional has been widely used to preserve edges and remove the staircase effect in the resulting images. However, the Euler-Lagrange equations of a mean curvature model can be used to solve fourth-order non-

Online Spatiotemporally Constrained Reconstruction for Real-Time Interactive MRI. [PDF]

open access: yesMagn Reson Med
ABSTRACT Purpose To develop a low‐latency dynamic MRI reconstruction that provides better spatial and temporal fidelity than contemporary online reconstruction, for localization. Methods We utilize online spatiotemporally constrained reconstruction (STCR) using a computationally efficient augmented Lagrangian solution and a limited number of iterations

A Decomposition Augmented Lagrangian Method for Low-Rank Semidefinite Programming [PDF]

open access: yesSIAM Journal on Optimization, 2021
We develop a decomposition method based on the augmented Lagrangian framework to solve a broad family of semidefinite programming problems, possibly with nonlinear objective functions, nonsmooth regularization, and general linear equality/inequality ...

A novel augmented Lagrangian method of multipliers for optimization with general inequality constraints [PDF]

open access: yesMathematics of Computation, 2021
We introduce a twice differentiable augmented Lagrangian for nonlinear optimization with general inequality constraints and show that a strict local minimizer of the original problem is an approximate strict local solution of the augmented Lagrangian.
