Chris,
it is interesting to me that IA-MMPO (implicit approval minus max pairwise
opposition) gives the same results as Approval Seeded by MinGS (etrw) in
the four examples that you offered:
> 46 A
> 44 B>C
> 10 C
>
The respective IA-MPO scores for A, B, and C are 46-54, 44-46, and 54-46,
the only positive one.
> 46 A
> 44 B>C (sincere might be B or B>A)
> 05 C>A
> 05 C>B
The respective IA-MPO scores are 51-54, 49-51, and 54-46, again the only
positive one.
46 A>C
> 10 B>A
> 10 B>C
> 34 B=C
>
The respective IA-MPO scores are 56-54, 54-46, and 90-56. C wins again.
> 40 A>C
> 15 B>A
> 20 B
> 15 C>A
> 10 C
>
The respective scores are 70-35, 35-65, and 65-55. This time A wins with
an IA-MPO score of 35 compared to C's 10.
This IA-MPO method does satisfy the FBC, but is not chicken proof.
However, small defensive moves can thwart chicken threats.
It seems like I might have suggested IA-MPO before, but we were trying for
something fancier at the time.
