[EM] Voting correction

2005-03-29 Thread MIKE OSSIPOFF
I said in a previous message: "For instance, with the candidate lineup of James' example (Kerry, Bush, Dean), I'd rate them all zero, because none of them is any good, and none of them deserves a vote." I meant that I'd give _minimum_ points to all three candidates, Kerry, Bush, and Dean. So if

Ralph-- I'd said: With CR, it's transparently obvious that no one has any reason to not give maximum points to their favorite--that giving maximum points to compromise Kerry is in no way weakened by also giving maximim points to favorite Nader. You replied: You are surely mistaken. There will peopl

Chris described a kind of voting and asked me...what I would call it. I said "offensive order-reversal", but that was a hasty incorrect answer, based on how I've defined offensive strategy. I've defined offensive strategy as strategy intended to take victory from a CW or to elect someone in viol

2005-03-29 Thread MIKE OSSIPOFF
I'd said: Yes, but to outdo a majority pairwise vote, it's necessary for that MPV to be in a cycle of MPVs _all of which are at least as strong as it is_. You say: In 1997, I proposed the following method (Schulze method, Schwartz sequential dropping, cloneproof Schwartz sequential dropping, beatpa
