I'm not quite sure what you mean by iteratively restricting the set.
Could you give me an example of how the method works? Say, Schulze's
five candidate example:
5: A>C>B>E>D
5: A>D>E>C>B
8: B>E>D>A>C
3: C>A>B>E>D
7: C>A>E>B>D
2: C>B>A>D>E
7: D>C>E>B>A
8: E>B>A>D>C
if it wouldn't be too tedious? It's got a large Smith set.
