ABC voting and BTR-Score are the single best methods by VSE I've ever seen.

Perhaps testing voting systems is analogous to testing digital security, let people try to hack a new voting system. Computer simulations would be one method of hacking, creative humans, another.
Yes, real political elections are the best tests, but we have to get there from here.
-
@gregw there is a cyber security technique called "fuzzing" in which attacks are simulated with random data. The VSE simulations seem to provide a framework for fuzzing, where in this case the random data would be some kind of strategy. Developing a genetic algorithm to evolve a strategy that breaks a system would be an interesting side project. When I get the spare time and energy, I'll see if I can cook one up and set up a computer to just chug away at it until I have some results. (I wrote and published a library called bluegenes in case anyone wants to try stapling libraries together before I get around to it.)

A great idea! To determine the best voting systems, we need to find the weaknesses of each voting system. Better testing methods are key. A tool like you propose would be invaluable.

@k98kurz it’s really great you’re working on these kinds of reinforcement learning methods in this field, definitely something both very interesting and that can give us insight into how these systems work. Looking forward to hearing about any of the work in this area!

Actually I do not have the mathematical expertise. If my new nonprofit, Voters Takes Charge, (under construction at voterstakecharge.us password no longer needed) receives generous support we may be able to commission such work.

I wish this investigation had included BTR-RCV
(side-note: don't call it BTR-IRV, that includes "runoff" twice and is less-clear as a name)

@ex-dente-leonem
I wanted to create some figures for an article on MARS voting that I plan to write, but fail to run vse-sim. Is it okay for you when use your results? -

Does anyone know if BTR-Score is immune to turkey-raising / DH3?

@isocratia
Good question. According to Electowiki:Methods that pass dominant mutual third burial resistance [DMTBR] provide no incentive to bury under a dark horse.
Following the argument here it is clear that BTR-score fails DMTBR
In election (A) and (B) A wins. In (D) the winner is C, but in (E) the winner is A again. (I assumed score from 0 to 2.)
where A is the CW, and so (E)->(D) is a DMTBR failure.
But this does not exclude the possibilty that the score part reduces the strategic incentive to bury.

How should ABC voting treat unmarked candidates?
-
@jack-waugh I think anything except the minimum for unmarked candidates makes it too easy to mark bullet burials. But I don’t know.
