Computational Social Choice Seminar


This is the programme of the Computational Social Choice Seminar at the Institute for Logic, Language and Computation (ILLC) at the University of Amsterdam. The talks mostly address issues at the interface of computer science (including logic and and artificial intelligence) and mathematical economics (including social choice theory, game theory, and decision theory). Talks take one hour, including questions. All welcome!
