About OllPoll

OllPoll is a two-pass score-to-vote proportional representation voting method designed for party-list elections.

In general it uses 0-to-N range ballots, each ballot is worth up to N votes. It works like this:

1st pass: sum up the scores then sort the parties from highest to lowest scoring ones
2nd pass: for each ballot:
- stalin-sort the parties on the ballot, eliminate the ones that did not increase the score
- by how much the party increased the score is the number of votes it receives
sum up the votes and allocate seats proportionally

For small number of voters (committee, judges, etc...) use 0-to-5 range ballots. For general elections use 0-to-2 ballots.

With 0-to-2 ballots (2 - favorites, 1 - acceptable, 0 - the rest) the algorithm becomes more specific:

sum up the scores, order the parties from strongest to weakest
each ballot is worth up to 2 votes
- 1 vote goes to the strongest party on the ballot
- 1 vote goes to the strongest favorite on the ballot
sum up the votes and allocate seats proportionally
