CIRCA is a coarse-grained architecture designed to control autonomous systems which require both intelligent, deliberative planning activity and highly reliable, hard real-time reaction to safety threats. The MASA-CIRCA project extended this architecture with the ability to reason accurately about its own real-time behavior, and adapt that behavior in response to performance feedback. Major issues investigated during this project include formally verifying real-time control plans, dynamically decomposing long-term plans into sub goals, and building realtime control plans using probabilistic information to reason about most-likely states first. We provided digital video demonstrations of these features, with MASA-CIRCA operating in a combat oriented multi-aircraft flight simulation domain. This report is intended to provide an overview of the project research. This report makes numerous references to more-detailed publications that have been generated during the project.

NUMBER OF PAGES 14. SUBJECT TERMSiv MASA-CIRCA: Multi-Agent Self-Adaptive Control for Mission-Critical Systems Abstract This is the final report for the Defense Advanced Research Projects Agency (DARPA) contract F30602-00-C-0017 entitled "MASA-CIRCA: Multi-Agent Self-Adaptive Control for Mission-Critical Systems." The goal of this contract effort was to begin extending the Cooperative Intelligent Real-Time Control Architecture (CIRCA) with abilities to automatically monitor its own performance and adapt in real-time, forming Multi-Agent SA-CIRCA (MASA-CIRCA). CIRCA is a coarse-grain architecture designed to control autonomous systems which require both intelligent, deliberative planning activity and highly reliable, hard-real-time reactions to safety threats. CIRCA allows systems to provide performance guarantees that ensure they will remain safe and accomplish mission-critical goals while also intelligently pursuing...
