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 diagram|Yee diagrams]].
* Tallying elections with given inputs, currently only through a web interface.<ref>{{cite web| url=https://rangevoting.org/VoteCalc.html |access-date=2020-02-20|title=IEVS voting calculator}}</ref>

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.<ref>{{cite web| url=https://www.reddit.com/r/EndFPTP/comments/dl54fw/rangevotings_bayesian_regret_simulations_with/ |title=RangeVoting's Bayesian Regret Simulations with Strategic Voters Appear Severely Flawed}}</ref>
