An Oxford-led team has won the best paper award at the Nineteenth International Conference on Theoretical Aspects of Rationality and Knowledge (TARK-2023). The conference was founded in 1986, and studies issues that arise at the intersection of AI, economics, and philosophy connected with rationality, knowledge, and decision making.

James Fox, Matt MacDermott, Lewis Hammond, Paul Harrenstein, Alessandro Abate and Michael Wooldridge were awarded the prize for the paper On Imperfect Recall in Multi-Agent Influence Diagrams which shows how a popular game theoretic model can be extended to deal with a commonly occurring situation called imperfect recall. The work is of relevance to researchers in AI who want to understand how AI systems can effectively interact with one-another.

James and Lewis are DPhil students in the Department of Computer Science; Paul is a postdoc in Computer Science; Alessandro and Michael are academics based in Computer Science; and Matt is a PhD student at Imperial College London.
