Multi-agent systems is an evolving discipline that encompasses many different branches of research. The long-standing Agents at Aberdeen (A 3) group undertakes research across several areas of multiagent systems, focusing in particular on aspects related to resilience, reliability, and coordination. In this article we introduce the group and highlight past research successes in those themes, building a picture of the strengths within the group. We close the paper outlining the future direction of the group and identify key open challenges and our vision towards solving them.
