Robust Distributed Stabilization of Interconnected Multiagent Systems
<p>Many large-scale systems can be modeled as groups of individual dynamics, e.g., multi-vehicle systems, as well as interconnected multiagent systems, power systems and biological networks as a few examples. Due to the high-dimension and complexity in configuration of these infrastructures, only a …

Agreement, Information and Time in Multiagent Systems
This dissertation studies multiagent agreement problems -- problems in which a population of agents must agree on some quantity or behavior in a distributed manner. Agreement problems are central in many areas, from the study of magnetism (Ising model), to understanding the diffusion of innovations …

Decentralized teaching and learning in cooperative multiagent systems
Cooperative multiagent decision making is a ubiquitous problem with many real-world applications, including organization of driverless car fleets [1, 2], target surveillance [3], and warehouse automation [4-6]. The unifying challenge in these real-world settings is the presence of domain …

Knowledge Representation, Communication, and Update In Probability-Based Multiagent Systems
<p>In this dissertation, we define a cooperative multiagent system where the agents use locally designed Bayesian networks to represent their knowledge. Agents communi- cate via message passing where the messages are beliefs in shared variables that are represented as probability distributions. …

Distributed adaptive control methods for uncertain multiagent systems with coupled dynamics
<p>For a multiagent system, a major challenge is achieving overall system stability and performance in the presence of not only uncertainties but also coupled dynamics. Another challenge for these systems is designing distributed adaptive controllers with user-assigned positions in this case and …

A rational choice framework for collective behavior
… together. A simple result from the literature on multiagent systems suggests that strong general collective intelligence in the form of "rational group agency" arises from three conditions: aligned utilities, accurate shared beliefs, and coordinated actions. However, achieving these conditions can …

Multiagent planning with Bayesian nonparametric asymptotics
Autonomous multiagent systems are beginning to see use in complex, changing environments that cannot be completely specified a priori. In order to be adaptive to these environments and avoid the fragility associated with making too many a priori assumptions, autonomous systems must incorporate some …
