James G-A replying to Mike, on a few strategy-related issues...

It is a separate problem if it succeeds. It may resemble existing compromising problems more closely if other voters counteract it using a compromising counterstrategy (a defensive strategy, in your terms).

No, it's not unique to Condorcet methods. It's also present in Borda, Bucklin, approval, and CR. Not in IRV, though. See Blake's page http://condorcet.org/emr/methods.shtml Mike: > >And, by the way, what do you call offensive truncation? "Compression"? If >you move Kerry up to 1st place with Nader, is that compression, or >compromising, or raising, or all of those? The compression/reversal distinction for strategy terms was an idea that I introduced on 3/29/04. http://lists.electorama.com/pipermail/election-methods-electorama.com/2004-March/012515.html If my sincere preferences were N>K>B and I voted N=K>B in order to decrease Bush's chances of winning, that would be the compromising-compression strategy. If I voted K>N>B, to achieve the same end, that's the compromising-reversal strategy. Either way, it's a compromising strategy. And yes, I would say that I would be raising Kerry rather than lowering Nader, since my goal wouldn't be to decrease Nader's chance of being elected (although I may accept this as a side effect of my goal to decrease Bush's chances of being elected). > Sincerely, James ---- Election-methods mailing list - see http://electorama.com/em for list info
