AAMAS is the leading scientific conference for research in autonomous agents and multi-agent systems. The AAMAS conference series was initiated in 2002 as a merger of three highly respected individual conferences: the International Conference in Autonomous Agents, the International Workshop on Agent Theories, Architectures, and Languages, and the International Conference on Multi-Agent Systems. The aim of the joint conference is to provide a single, high-profile, internationally respected archival forum for research in all aspects of the theory and practice of autonomous agents and multi-agent systems.
Although the conference is AI oriented, there is a good portion of papers from a theoretical computer science, algorithms and game theory perspective. It will also be a good opportunity to listen to some really interesting presentations and tutorials. There are also accompanying workshops.
The conference also has a doctoral training program especially for final year PhDs. However, I did not register for that. This is because the training program required too much extra paper work for participation. Moreover, if I want to get advice I can just go and ask the person concerned. Academics are generally very approachable people.
Budapest itself is an amazing city and I look forward to taking some time out to look around.
