[EM] Condorcet Flavored PR Methods

[Adam Tarr]

2 more questions about Condorcet-PR:

- is there any sequential version of this?  I can't figure one, since the 
placement of the cutoffs depends on the total number of candidates being 
elected.

- I will admit this is the first election method I've dealt with where I 
have trouble manipulating small examples.  Here's a very small example that 
was gibing me trouble: say we are electing two candidates out of four.  My 
ballot is: A(>B=C=D).  The pairwise matrix will be 6x6 (with 6 empty 
slots).  With respect to my ballot, every comparison is equivalent to one 
of the following:

AB vs. CD
(k1 + j2 = 1 + 1 = 2?  k2 + j1 = 0 + .5 = .5?)

or

AB vs. BD
(k1 + j2 = .5 + 1 = 1.5?  k2 + j1 = 0 + 1 = 1?)

or

AB vs. AC

(k1 + j2 = k2 + j1 = 1.5 + .5 = 2)

Do the summations I wrote make sense?  The results (except the trivial last 
one) seem a bit odd.  I was toying with this example to try and measure how 
equivalent your Condorcet-PR method is to PAV in situations where the 
voters vote in an approval-like fashion.
