The NYT with a piece on alternative voting.
Instant runoff voting is a different bird than proportional representation but I do not know the political science literature well enough to know exactly how one would expect it to differ.
I have always been a fan of including "none of the above" on the ballot, with a new election held (with new candidates) if it wins.
