Welcome to votingmethods.net

This is the election methods website of Kevin Venzke. The content is mostly theory, and mostly related to single-winner rank ballot methods. I hope readers may find it interesting.

I follow the election-methods mailing list. Read it from the beginning here.

Interactive content:
Rank Ballot Election Calculator – results for 40+ methods, of all sorts, without resolution details.
Condorcet Calculator – demonstrating the main Condorcet methods using winning votes.
Condorcet Cycle Checker – a tool for method designers concerned about favorite betrayal.
Later-No-Harm Method Calculator – an exhibition of the methods satisfying Douglas Woodall's Later-no-harm property.
Miscellaneous Method Calculator – some nice methods satisfying neither Condorcet nor Later-no-harm.
Condorcet Compromise Extension – a proposal extending Condorcet in line with a typical motivating argument for Condorcet.
Who is the median voter? – speculations on identifying this hypothetical voter from cast votes.

Other topics:
