Here's the scenario you used to first show your tree method of determining delegation order. 16 A1A2B 12 A2A1B 24 BA1=A2 48 C What if some candidate outside the A1 A2 faction had an A2A1 preference? I mean either: Scenario S 16 A1A2B 12 A2A1B 24 BA2A1 48 C Or: Scenario T 16 A1A2B 12 A2A1B 24

Jameson, I'm really liking the SODA method that is evolving. I have a couple of cosmetic suggestions: First, in the description of SODA, I dislike using the term delegate for step 3, candidate-to-candidate transfers. I would only use the word delegate for step 2, the bullet voters' votes

On my web page where I describe my Proportional Range Voting System (http://www.tobypereira.co.uk/voting.html), I have suggested that it should be possible for a computer to sort out the result in a reasonable amount of time. Of course, this may not actually be the case considering the number

Assume you have some way to score the goodness of a slate of representatives. You want to find the best possible such slate, but you don't have the computational resources to score all possible slates. The options are: 1. Add candidates one at a time. Advantages: deterministic and simple.

Russ's message about simplicity is well-taken. But the most successful voting reform is IRV - which is far from being the simplest reform. Why has IRV been successful? I want to leave this as an open question for others before I try to answer it myself. The one answer which wouldn't be useful

I'm not sure I exactly followed that. Jameson's option 2 is to look at the nominated slates and see which is best. You could also still use one of the other methods to find a possible winner and then compare it with the best nominated slate (if they are different). Is that anything like what

The intended difference was that in option 2 one can use any optimization algorithm, and after some time we will see who has found the best slate, while in the proposed new variant of the option we would have a known algorithm, that would be run with known previously agreed parameters. And
