Infinitely Extendible Voting System

From electowiki

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.[1]

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.[2]
