The '''Schulze method''' ({{IPAc-en|ˈ|ʃ|ʊ|l|t|s|ə}}), also known as the '''beatpath method''', is a [[single winner]] [[Ranked voting|ranked-choice voting rule]] developed by Markus Schulze. The Schulze method is a [[Condorcet method|Condorcet completion method]], which means it will elect a [[majority-preferred candidate]] if one exists. In other words, if most people rank ''A'' above ''B'', ''A'' will defeat ''B'' (whenever this is possible). Schulze's method breaks [[Cyclic tie|cyclic ties]] by using indirect victories. The idea is that if [[Alice and Bob|Alice]] beats Bob, and Bob beats Charlie, then Alice (indirectly) beats Charlie; this kind of indirect win is called a "beatpath".

For [[proportional representation]], a [[single transferable vote]] (STV) variant known as [[Schulze STV]] also exists. The Schulze method is used by several organizations including [[Debian]], [[Ubuntu (operating system)|Ubuntu]], [[Gentoo Linux|Gentoo]], [[Pirate Party]] political parties and [[Schulze method#Usage|many others]]. It was also used by [[Wikimedia]] prior to their adoption of [[score voting]].
