[EM] Minor corrections to yesterday's postings

[MIKE OSSIPOFF]

Just to somewhat neaten-up (but not necessarily perfect) this definition:

Acceptable/Unacceptable situation:

For a particular voter, an acceptable/unacceptable situation exists if, for 
that voter, all the candidates are in two sets such that the voter would 
rather maximize the probability that the winner will come from one of those 
sets than influence, for one of those sets, which member of one of the sets 
wins instead of a different member of that set.

The set that that voter wants the winner to come from is the "acceptable 
set", and the other set is the "unacceptable set". Their members are, 
respectively, the acceptable candidates and the unacceptable candidates.

[end of acceptable/unacceptable situation definition]

I was a bit unfair to wv yesterday. I said that someone could ask how wv is 
better than IRV. Of course wv is better than IRV because, in the 
acceptable/unacceptable situation, it's usually optimal to equal rank 
instead of favorite-bury.

Ironically, adding AERLO to wv increases favorite-burial, for the optimizing 
voter in an acceptable/unacceptable situation.
