Modeling Uncertainty and its Implications to Sophisticated Control in Tæms Agents

Thomas A. Wagner, Anita Raja, Victor R. Lesser
2006 Autonomous Agents and Multi-Agent Systems  
We describe the uncertainty representation in TAEMS and how it improves task models and the scheduling process, and provide empirical examples of reason-1 ing about uncertainty in action.  ...  As we show, the use of uncertainty in TAEMS and Design-to-Criteria enables agents to make better control decisions in uncertain environments.  ...  Acknowledgments We would like to acknowledge the work and contributions of Professor Alan Garvey.  ...

Investigating Interactions between Agent Conversations and Agent Control Components [chapter]

Thomas Wagner, Brett Benyo, Victor Lesser, Ping Xuan
2000 Lecture Notes in Computer Science  
Introduction Based on a long history of work in agents and agent control components for building distributed AI and multi-agent systems, we are attempting to frame and address a set of intellectual questions  ...  A coordination mechanism, in contrast, denotes a larger grouping of concerns -it is the way in which an agent reasons about interactions, plans to resolve them, and carries out communication activities  ...  Typically a problem solver represents domain problem solving actions in TAEMS, possibly at some level of abstraction, and then passes the TAEMS models on to agent control problem solvers like the multi-agent  ...

Implementing soft real-time agent control

Régis Vincent, Bryan Horling, Victor Lesser, Thomas Wagner
2001 Proceedings of the fifth international conference on Autonomous agents - AGENTS '01  
In this paper we describe a realtime environment requiring distributed control, and how we modified our existing multi-agent technologies to meet this need.  ...  The complexity associated with these systems increases as control and autonomy are distributed, due to such issues as precedence constraints, shared resources, and the lack of a complete and consistent  ...  One direction is to make it more sophisticated in its understanding exactly what previously scheduled event(s) is responsible for the conflict. Figure 1 : 1 High-level agent control architecture.  ...

A framework for meta-level control in multi-agent systems

Anita Raja, Victor Lesser
2007 Autonomous Agents and Multi-Agent Systems  
Sophisticated agents operating in open environments must make decisions that efficiently trade off the use of their limited resources between dynamic deliberative actions and domain actions.  ...  Control activities involve decisions on when to invoke and the amount to effort to put into scheduling and coordination of domain activities.  ...  Acknowledgments We would like to thank Professor Shlomo Zilberstein for his help in constructing the model described in Section 2.1 and Professor Andy Barto for his valuable comments on the Reinforcement  ...

Resource-Driven Mission-Phasing Techniques for Constrained Agents in Stochastic Environments

J. Wu, E. H. Durfee
2010 The Journal of Artificial Intelligence Research  
In this paper, we formally define and analyze this constrained, sequential optimization problem in both the single-agent and multi-agent contexts.  ...  Such agents can, in general, achieve more of their objectives if they can use --- and even create --- opportunities to change which resources they hold at various times.  ...  The authors thank Dmitri Dolgov and the three anonymous reviewers for their very helpful suggestions and comments, and Stefan Witwicki and Jim Boerkoel for their help in proofreading this article.  ...

Towards a Framework for Agent Coordination and Reorganization, AgentCoRe [chapter]

Mattijs Ghijsen, Wouter Jansweijer, Bob Wielinga
Coordination, Organizations, Institutions, and Norms in Agent Systems III  
Therefore, the view of coordination and control has to be expanded to consider not only an agent-centric perspective but societal and organization-centric views as well.  ...  Openness, heterogeneity, and scalability of MAS pose new demands on traditional MAS interaction models.  ...  The author wants to thank Marek Sergot for his advise and hospitality. He also thanks Juan-Antonio Rodríguez-Aguilar and Pablo Noriega for their comments and reviews.  ...
