Proportional approval voting: Difference between revisions

'''Proportional approval voting''' (PAV) is a theoretical [[voting system]] for multiple-winner elections, in which each voter can vote for as many or as few candidates as the voter chooses. It was developed by the Danish polymath Thorvald N. Thiele, and its [[Sequential proportional approval voting|sequential approximation]] was used in Swedish elections up until its replacement by the less computationally laborious party-list system.<ref>{{cite web |url=http://www2.math.uu.se/~svante/papers/sjV6.pdf |title=Proportionella valmetoder |date=2012-08-20|last=Janson |first=Svante|journal=Typescript, Uppsala|access-date=2020-02-28}}</ref> andIt was thenlater rediscovered by Forest Simmons in 2001.<ref>{{cite web | title=Proportional Representation via Approval Voting | website=Election-methods mailing list archives | url=http://lists.electorama.com/pipermail/election-methods-electorama.com/2001-January/070294.html | access-date=2020-02-28 |date=2001-01-12 |first=Forest |last=Simmons}}</ref>

Both the [[Phragmén's Method]] and [[w:Sequential_proportional_approval_voting|Sequential Proportional Approval Voting]] are very similar systems invented in the early 1900s. [[Reweighted Range Voting]] is thean extension of this concept to [[Score Voting]], along with [[Harmonic Voting]] and its sequential counterpart, [[Sequential proportional score voting]]. These systems all derive their reweighting theory as the natural extension of the [[Jefferson Method]] to [[Multi-Member System]]s.
