Range voting Warren D. Smith

*Range voting*
is a single-winner voting system in which each vote consists of one numerical score
from 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 voting
election; advise 99/0 for best/worst.

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