Many voting rules are available for making a collective decision. The axiomatic approach in social choice is about investigating the properties of the rules. Depending on the context and what properties are important for a particular decision, one can then recommend a (small) set of particular voting rules. Another approach to collective decision could use multiagent learning and let agents repeatedly interact to decide on the decision, and this is what we start to investigate. By conducting extensive simulations, we show that our agents are capable of learning how to make decisions at the level of well-known voting procedures, and that these decisions maintain good choice-theoretic properties when increasing the number of agents or candidates.
Stéphane Airiau is assistant professor of Computer Science at the university Paris Dauphine. His research lies in artificial intelligence and more precisely in the field of multiagent systems. He is interested in engineering good and fair collective decision mechanisms.
