Local Independence of Irrelevant Alternatives

Since LIIA is one of the few criteria where Schulze and ranked pairs differ, should the article give an example where Schulze fails it or link to an external reference? WildGardener (talk) 01:22, 9 December 2020 (UTC)[reply]

In this example, the Schulze ranking is C > D > B > A. However, when candidate C is removed, then the Schulze ranking of the remaining candidates is D > A > B.
I had added this example in 2009 (diff). However, this example was removed by Daveagp in 2011 (diff). I didn't reinsert this example because I didn't want to be accused of starting an edit war. Markus Schulze 07:52, 9 December 2020 (UTC)[reply]
Thanks for the background! I didn't realize there was past history on this already. WildGardener (talk) 00:47, 10 December 2020 (UTC)[reply]

Simpler example

The 5-candidate pentagram example probably scares some people off. ;)

Maybe we could try simpler examples? 4 candidates is enough to show how Schulze differs from Minimax, without cluttering everything up with too many arrows (6 arrows total, and you can display them without intersections, vs. 10 arrows for a 5-candidate race). –Maximum Limelihood Estimator 17:02, 23 April 2024 (UTC)[reply]
