A Resilient Distributed Algorithm for Solving Linear Equations
Jingxuan Zhu, Alvaro Velasquez, Ji Liu
This paper presents a resilient distributed algorithm for solving a system of linear algebraic equations over a multi-agent network in the presence of Byzantine agents capable of a…
Heterogeneous Distributed Subgradient
Yixuan Lin, Ji Liu
The paper proposes a heterogeneous push-sum based subgradient algorithm for multi-agent distributed convex optimization in which each agent can arbitrarily switch between subgradie…
A Hybrid Observer for Estimating the State of a Distributed Linear System
Lili Wang, Ji Liu, A. Stephen Morse
A hybrid observer is described for estimating the state of a system of the form dot x=Ax, y_i=C_ix, i=1,...,m. The system's state x is simultaneously estimated by m agents assuming…
Cooperative Actor-Critic via TD Error Aggregation
Martin Figura, Yixuan Lin, Ji Liu +1
In decentralized cooperative multi-agent reinforcement learning, agents can aggregate information from one another to learn policies that maximize a team-average objective function…
Exponential Convergence of a Distributed Algorithm for Solving Linear Algebraic Equations
Ji Liu, A. Stephen Morse, Angelia Nedich +1
In a recent paper, a distributed algorithm was proposed for solving linear algebraic equations of the form assuming that the equation has at least one solution. The equati…
Lyapunov Approach to Consensus Problems
Angelia Nedich, Ji Liu
This paper investigates the weighted-averaging dynamic for unconstrained and constrained consensus problems. Through the use of a suitably defined adjoint dynamic, quadratic Lyapun…
