[EM] Method X, bummer

[Kevin Venzke]

Hi Forest, is IACC the same thing as TACC (i.e. initial head is the least approved)? Because I don't find TACC to be monotone.

I actually don't know or haven't implemented any monotone Landau method. Not that I have really looked hard for one.

Do you consider Implicit Approval Chain Climbing to be burial resistant?

It certainly punishes the burying faction on all of the examples Chris gave highlighting his MinLosingVotes Pairwise Margins method.

As a reminder it is the only Banks efficient monotone, clone independent, Universal Domain method that we know of so far.

In general, Agenda Based Chain Climbing is monotone when the agenda formation is monotone ... so Borda and Kemeny Chain Climbing are also Banks efficient monotone methods that are probably burial resistant, but neither one is clone proof.

In general, elimination with "take down" is Banks efficient ... but not monotone unless based on a fixed (no renormalization between eliminations) monotone agenda.

Implicit Approval is monotone and clone proof and UD, but just barely UD. It is maddenly frustrating trying to find another UD monotone, clone proof agenda forming method.
