Agents at Aberdeen (A³) is a research theme with a long history of investigating a wide variety of research topics related to autonomous agents, multi-agent systems and knowledge representation and reasoning. Our recent focus has been on exploring resilience, reliability, and coordination in autonomous multi-agent systems. We apply these techniques to a wide range of application domains, including but not limited to: emergency response, healthcare, decision-making in robotic systems, self-driving cars, explainability, and software engineering.
