Summary

This project investigates mathematical model-based methods as a framework for coordination in intelligent agent societies.

The first step is identifying the relevant aspects of intelligent agent behavior. These aspects are mapped to state variables that describe the behavior of a society of agents. Dependencies between activities then manifest themselves as relationships between these aspects or state variables. Coordination, the process of managing dependencies between activities, is viewed as the exertion of control over these relationships. Such control can best be understood when the state variables' dynamics can be represented by constructs based on logic or ordering (partial or total), or both. The question of imposing logical structure and partial or total orderings on the identified variables (and hence, on the corresponding aspects of intelligent social behavior) is therefore being examined.

Once the relationships governing a society are known, coordination problems are reduced to optimization, constraint satisfaction, and constraint propagation problems. Existing techniques and research in these fields then become available for formal approaches to coordination.

The project is aimed at demonstrating the viability of the approach. This objective is being achieved by constructing mathematical models of typical intelligent agent societies using the state variable framework described above. Simulations of typical artificial intelligent agent societies are built ab initio (separately from the mathematical models). These simulations are used to test and validate the mathematical model(s). Given a preliminary validation of the framework based on simulation models, subsequent research may examine its validity and applicability to various actual artificial intelligent agent societies.

The framework described will facilitate theoretical and simulation-based approaches to coordination mechanisms, and produce valuable insights into the fundamental problems of coordination. This should lead to (i) a taxonomy of intelligent agent societies; (ii) a methodology for modeling intelligent agent societies using such taxonomy; and (iii) foundations for modeling and analyzing coordination using such methodology.
