Proportional approval voting: Difference between revisions

Line 1:

'''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<ref>http://www2.math.uu.se/~svante/papers/sjV6.pdf</ref> and then rediscovered by Forest Simmons in [[2001]].

PAV works by looking at how "satisfied" each voter is with each potential result or outcome of the of the election.

Line 56:

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 the extension of this concept to [[Score Voting]]. These systems all derive their reweighting theory as the natural extension of the [[Jefferson Method]] to [[Multi-Member System]]s.
