'''Proportional approval voting''' (PAV) is a [[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> It was later 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>
