range voting

Range votingWarren D. Smith

Range votingis a single-winner voting system in which each vote consists of one numerical scorefrom 0 to U awarded to each candidate,where U is some positive number.In single-digit range voting U is 9,while two-digit range voting has U=99.(One could also consider permitting the interval to be, e.g. $[-10,10]$.)The candidate with the highest average score wins.In a common variant, “X” scores also are permitted for candidates(meaning:“I wish to express no opinion about this candidate”).For example (46,0,32,99) could be one vote in a 4-candidate two-digit range votingelection; advise 99/0 for best/worst.

Approval voting [1] is the degenerate form of range voting in whichthere are only two allowed scores: 0 and 1.
