[EM] Why All the Fuss?

[Forest Simmons]

Yes, that's the only one ... and it's the one I mentionedwhen Markus
expressed doubt about the existence of a monotonic Landau efficient method.

It took another decade to get a UD Landau method that was both monotone and
clone independent.

The first such method was Agenda Based Chain Climbing based on a
truncation/abstention count agenda.

I look at Friendly Voting methods as decloned versions of Copeland.

They seem to have more class than ABCC in many ways, including good
potential for Independence from Pareto Dominated Alternatives,  but hard to
make both Decisive and Clone Free in a satisfactory way without more than
one pass through the ballots or explicit strong approval cutoffs (as
opposed to implicit/ weak approval or strong equal-top rankings) as a good
basis for Martin Harper Lottery Probabilities to replace the random ballot
favorite probabilities (fpA, fpC, etc.) normally used in Friendly Voting to
declone Copeland.

[Without explicit strong approval cutoffs it takes one pass through the
ballots to find out who the Smith candidates are ... and if the median
ranked Smith candidate on a ballot should be an inclusive or exclusive
approval cutoff candidate.]
