[Election-Methods] Challenge: Elect the compromise when there'reonly 2 factions

[Paul Kislanko]

If I understand the meaning of the original example correctly, the answer is
Asset voting.

Give every voter 100 points. By the conditions given, both the A and B
voters think C is 80% as good as their true favorite, so give 5/9 of their
points to their favorite and 4/9 to C.

A's total is 55 x 5/9 = 275/9
B's total is 45 x 5/9 = 225/9
C's total is 55 x 4/9 + 45 x 4/9 = 100 x 4/9 = 400/9 so C wins.
