Talk:Counting Single Transferable Votes

From Wikipedia, the free encyclopedia

[edit] Changes

I re-jigged the changes to establish the difference between Hare and Cincinnati - they both use random redistribution of votes, but Hare's are from a randomly determined surplus, whereas cincinnati is drawn at regular intervals from the whole set, to ensure a fair spread. Also emmphasised that the transfers from Hare can be from first preferences as well as from later transfers.

This is not the essential difference. The method of randomisation is a separate issue from the set from which the surplus is selected. The term "Cincinnati method" does not encompass every aspect of the process used in Cambridge. I have created a separate heading for randomisation. I also added a new grouping to emphasise the difference between surplus for previously-unelected candidate, and transfers to already-elected candidate. Joestynes 03:22, 27 May 2005 (UTC)

Right, that looks fair enough, though I still think that the example isn't entirely up to snuff, since the surplus is transfered with Hare whether it's a surplus from transfers or a simple first preference - i.e. the last 20 of 220 1st preferences would likewise be transfered...--Red Deathy 07:02, 2005 May 27 (UTC)

That's true (except saying the "last" 20 votes presupposes some ordering, whereas votes are usually randomised). I've just added the statement that, where the surplus arises from first preferences, the Hare System and the Cincinnati System are equivalent. The example is designed to highlight the difference between them, which occurs when the surplus arises from transfers. Joestynes 07:29, 27 May 2005 (UTC)

I reformatted the page so that it would be a lot easier to read. Basically, just changed indents and such so that each of the different methods could be distinguished as a separate topic and bumped the Example to its own major heading. --Leep4life 20:37, 14 December 2005 (UTC)

[edit] Warren?

There is another technique, which also requires computer counting, called "Warren" - I assume, like "Meek" it's named for it's inventor. Can anyone explain the differences between the Meek and Warren methods? I think it's described in the Tidemann paper that introduced CPO-STV, but I can't find a copy of that any more - the link in CPO-STV is broken--Po8crg 02:03, 8 February 2006 (UTC)

[edit] Senatorial/Gregory

Do these methods really transfer fractional surpluses from all votes, or just those which arrived in the counting round which put the candidate over quota? I.e. are they a fraction version of Hare or of Cincinnati. The article currently suggests of Cincinnati (while saying Clarke) but I have seen a fractional version of Hare used. And the link [1] has a commentary for Dromore in 21 May 1997 saying "Of the 602 votes transferred to Gribben, 327 transferred further" suggesting that this is more Hare-like than Cincinnati-like. Similarly, is Clarke Hare-like or Cincinnati-like? --Henrygb 00:55, 22 April 2006 (UTC)
