Question
How does Single transferable vote (STV) work in multiwinner elections?
STV is a multistage elimination rule that works as follows. In each stage, if there is a candidate c whose Plurality score is at least $$q=\frac{|V|}{k+1}+1$$ (the so-called Droop quota), we do the following: (a) include c in the winning committee, (b) delete q votes where c is ranked first, so that each of these votes is ‘transferred’ to the candidate currently ranked right after c, and (c) remove c from all the remaining votes. If each candidate’s Plurality score is less than q, a candidate with the lowest Plurality score is deleted from all votes.
