4. Decision Making (2) 1. Voting
Coomb's method: Each voter ranks all candidates in linear
order. If there is no candidate ranked first by a
majority of all voters, the candidate which is
ranked last (by a majority) is eliminated. The
last remaining candidate wins.
d'Hondt's method: Each voter cast his votes. Seats are
V
allocated according to the quotient (V the
s+1
number of votes received, s the number of
seats already allocated).
Proportional Approving voting: Each voter gives points 1,
1
, 1, . . . , 1 for his candidates (he can choose as
2 3 n
many or few as she likes). The winning
candidates are those, where the sum of all
points is maximal (across all voters).
