Graph Feedback Controls Consensus and Clique Formation in Open-Weight Language-Model Populations
Samer Saab, Chaouki Abdallah
Multi-agent language-model (LM) systems often determine which agents communicate, yet routing is usually treated as an implementation detail. We ask whether routing itself determin…
A Model-Free Optimal Control Method With Fixed Terminal States and Delay
Mi Zhou, Erik Verriest, Chaouki Abdallah
Model-free algorithms are brought into the control system's research with the emergence of reinforcement learning algorithms. However, there are two practical challenges of reinfor…
Finite Horizon Multi-Agent Reinforcement Learning in Solving Optimal Control of State-Dependent Switched Systems
Mi Zhou, Jiazhi Li, Masood Mortazavi +2
In this article, a \underline{S}tate-dependent \underline{M}ulti-\underline{A}gent \underline{D}eep \underline{D}eterministic \underline{P}olicy \underline{G}radient (\textbf{SMADD…
Energy Optimal Control of a Harmonic Oscillator with a State Inequality Constraint
Mi Zhou, Erik I Verriest, Chaouki Abdallah
In this article, the optimal control problem for a harmonic oscillator with an inequality constraint is considered. The applied energy of the oscillator during a fixed final time p…
