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

Magn 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

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 ...

The Alternating Direction Search Pattern Method for Solving Constrained Nonlinear Optimization Problems

Mathematics, 2023
We adopt the alternating direction search pattern method to solve the equality and inequality constrained nonlinear optimization problems. Firstly, a new augmented Lagrangian function with a nonlinear complementarity function is proposed to transform the

Solving the TSP by the AALHNN algorithm

Mathematical Biosciences and Engineering, 2022
It is prone to get stuck in a local minimum when solving the Traveling Salesman Problem (TSP) by the traditional Hopfield neural network (HNN) and hard to converge to an efficient solution, resulting from the defect of the penalty method used by the HNN.
