Infinitely Extendible Voting System

The Infinitely Extendible Voting System or IEVS is an election simulator written by Warren Smith.

It has three main functions:


 * Calculating Bayesian regret.
 * Rendering Yee diagrams.
 * Tallying elections with given inputs, currently only through a web interface.

The latest version, version 3.24, was finished in February of 2007. It supports 68 voting methods.

There have been concerns about the assumptions underlying strategic voting.
