I just spoke with someone at Texas Tech. We were discussing how cascade voting might be used to elect a proportional assembly. Basically, you just take the roots and branches of the trees (straight from the election results) and that's your assembly. Is this roughly what you guys are proposing, in this sub-thread? ===== quote from private email ===== [This] solution depends on the candidate rankings, as revealed by the election results. For example, here are the current rankings in a demo election (in this case, for a Mayor): http://zelea.com:8080/votodemo/w/?wicket:bookmarkablePage=%3Avotorola.a.election.WP_Count&s=demo-mayor Or see the screen shot: http://zelea.com/project/votorola/a/web/_/guide/results.png (These results are unrealistic. The voters are mostly computer drones, and there's only a single cascade - 100% of the votes flowing to the leading candidate. Normally there'd be many cascades.) What you see in the rankings (above) corresponds to the roots, and to the thickest branches of the cascades, as they exist at a particular moment in time. For illustration, in the smaller election below, the top-ranked candidates are X, W, N and M (left cascade), and J and H (right). (I) (K) (L) \ 1 | 1 / \ | / 1 (A) (B) (P) (O) \ | / | 1 / (R) \ 1 | \|/ | / 1 \ 1 \ | 1 (M) | / \ \ | | | / (E) (F) \ \| | 4 |/ | 1 / 1 \ (Q) | (C) | / 1 (S)-----(T) \ 3 | | | / \ 3 \ | | 3 |/ \ \ | | (H)-----(G) \ \ | (D) | / 1 1 2 \ \| \ 1 | / (U)-----(V)-----(W) (N) \ | / 4 \ 6 / \ | / \ / 8 \|/ \ / (J) \ / (X) 8 --- 14 ---- The solution is to call an election for a proportional assembly... and use the ranked results to populate the seats (N seats). If we open the voting to the entire jurisdiction... and take the top N candidates (rank 1 to N) from the results, enrolling them in the assembly, then the membership will accurately reflect the structure of the electorate. If N=6, for instance, the current members of the assembly are: X, W, N, M (left side) J, H (right) We could re-enroll the assembly at frequent intervals. People will be continually shifting their votes as new information becomes available to them, and the rankings may shift as a result. ===== end quote ===== My own work is aimed at using a delegate cascade to open actual legislation, policies, and so forth, to direct voting. But it's interesting to consider how it might interplay with PR elections. -- Michael Allan Toronto, 647-436-4521 http://zelea.com/ ---- Election-Methods mailing list - see http://electorama.com/em for list info
