The workshop will take place on February 8 and 9 at TU Wien.

Second Vienna-Graz Workshop on (Computational) Social Choice


Computational social choice is a rapidly growing field of research at the intersection of computer sciences, economics, and political science that studies how we can make collective decisions in a better and fairer way, from the distribution of household chores to national elections. The Series “Vienna-Graz Workshop on (Computational) Social Choice” aims to bring together researchers from Vienna, Graz and beyond that work on (Computational) Social Choice and related fields. After a first successful edition in Graz, we are proud to host this year’s edition at TU Wien.
