Paradoxes of Voting
Speaker: Lachlan Dufton, University of Waterloo
Voting is ubiquitous wherever groups of individuals must
make collective decisions. These decisions can range from high
importance,such as the selection of a government or a country's
policies, to the more trivial, such as where to go for dinner.
Unfortunately, voting systems are subject to many paradoxes and
impossibility results. In fact, every voting system is vulnerable to
at least one paradox. In this talk, I will cover some common voting
systems and the various paradoxes or problems that affect them. I will
also discuss how these problems are handled, particularly as examined
in the field of Computational Social Choice.
