Method Detail

name

public java.lang.String name()

Description copied from class: VotingSystem

Overrides:

name in class Condorcet

Returns:

a descriptive name

voteRating

public int voteRating(int[] rating)

Overrides:

voteRating in class Condorcet

Parameters:

rating - An array int[numc]. rating[i] is the rating of choice i. A rating can be any int value. Higher means more preferred. NO_VOTE for unrated.

Returns:

0 on success

voteRating

public int voteRating(float[] rating)

Overrides:

Parameters:

rating - An array int[N]. rating[i] is the rating of choice i. A rating can be any int value. Higher means more preferred. NO_VOTE for unrated.

Returns:

0 on success

voteRating

public int voteRating(double[] rating)

Overrides:

voteRating in class Condorcet

Parameters:

indecies of winners (hopefully 1 of them)
