Talk:Dodgson's method

swaps
The method depends on "swaps", but swaps of what? Overall candidate rankings? Rankings on individual ballots? Something else? —Tamfang (talk) 21:42, 3 December 2017 (UTC)


 * I would assume it means swaps of data. For reference, possibly see the Bogosort 24tiptlo (talk) 06:16, 17 January 2022 (UTC)
 * Swaps of neighboring candidates, I believe? Closed Limelike Curves (talk) 20:10, 11 April 2024 (UTC)

NP-Completeness

Borda instead of Condorcet?
Shouldn't it be "Borda count" instead of "Condorcet method"? --DL5MDA (talk) 06:41, 30 May 2018 (UTC)

Difference from Kemeny-Young?
@VoteFair (I'm guessing you're most likely to know): how is Dodgson's method different from Kemeny-Young? Is Dodgson just the single-winner (instead of ranking) form of Kemeny-Young?

From what I can tell, Kemeny-Young swaps candidates on ballots until it finds a Condorcet-dominance ordering of the candidates; Dodgson keeps swapping until it finds a single Condorcet-dominant candidate. If Kemeny-Young satisfies LIIA (which I think it does?), shouldn't this mean they're the same? Closed Limelike Curves (talk) 20:41, 11 April 2024 (UTC)


 * Hi,
 * they are indeed similar, but the outcomes they produce are different. For an easy example, see "A comparison of Dodgson's method and Kemeny's rule" by Ratliff. Jannikp97 (talk) 06:54, 12 April 2024 (UTC)
 * Yup, I found that and added it just a couple hours after posting this comment :p Closed Limelike Curves (talk) 15:12, 12 April 2024 (UTC)
