Algorithmic Decision Theory

The goal of the group is to develop computational and analytical tools to support collective and cooperative decision making, using a blend of game theory, artificial intelligence and algorithms.

We work on fundamental optimisation problems that need to take into account distributed agents, preferences, priorities, fairness, stability and the strategic concerns of the stakeholders. The group sits at the interface of computer science — in particular AI, multi-agent systems and theoretical computer science — and economics, in particular social choice, market design and game theory.
