Decentralized Optimization via RC-ALADIN with Efficient Quantized Communication
Xu Du, Karl H. Johansson, Apostolos I. Rikos
In this paper, we investigate the problem of decentralized consensus optimization over directed graphs with limited communication bandwidth. We introduce a novel decentralized opti…
Distributed Consensus Optimization with Consensus ALADIN
Xu Du, Jingzhe Wang
TThe paper proposes the Consensus Augmented Lagrange Alternating Direction Inexact Newton (Consensus ALADIN) algorithm, a novel approach for solving distributed consensus optimizat…
A Time Splitting Based Optimization Method for Nonlinear MHE
Shuting Wu, Yifei Wang, Jingzhe Wang +2
Moving Horizon Estimation~(MHE) is essentially an optimization-based approach designed to estimate the states of dynamic systems within a moving time horizon. Traditional MHE solut…
ALADIN-: A Distributed Optimization Algorithm for Solving MPCC Problems
Yifei Wang, Shuting Wu, Genke Yang +3
Mathematical Programs with Complementarity Constraints (MPCC) are critical in various real-world applications but notoriously challenging due to non-smoothness and degeneracy from…
