Robust Multi-Robot Trajectory Optimization Using Alternating Direction Method of Multiplier [PDF]
, 2022 We propose a variant of alternating direction method of multiplier (ADMM) to solve constrained trajectory optimization problems. Our ADMM framework breaks a joint optimization into small sub-problems, leading to a low iteration cost and decentralized ...

Alternating Direction Method of Multipliers for Quantization
CoRR, 2020 Quantization of the parameters of machine learning models, such as deep neural networks, requires solving constrained optimization problems, where the constraint set is formed by the Cartesian product of many simple discrete sets. For such optimization problems, we study the performance of the Alternating Direction Method of Multipliers for ...

A Fast Symmetric Alternating Direction Method of Multipliers
Numerical Mathematics: Theory, Methods and Applications, 2020 Summary: In recent years, alternating direction method of multipliers (ADMM) and its variants are popular for the extensive use in image processing and statistical learning. A variant of ADMM: symmetric ADMM, which updates the Lagrange multiplier twice in one iteration, is always faster whenever it converges.

Bregman Alternating Direction Method of Multipliers
CoRR, 2013 The mirror descent algorithm (MDA) generalizes gradient descent by using a Bregman divergence to replace squared Euclidean distance. In this paper, we similarly generalize the alternating direction method of multipliers (ADMM) to Bregman ADMM (BADMM), which allows the choice of different Bregman divergences to exploit the structure of problems.

Analysis of the Alternating Direction Method of Multipliers for Nonconvex Problems [PDF]
Operations Research Forum, 2021 This work investigates the theoretical performance of the alternating-direction method of multipliers (ADMM) as it applies to nonconvex optimization problems, and in particular, problems with nonconvex constraint sets. The alternating direction method of multipliers is an optimization method that has largely been analyzed for convex problems.
