Instant Runoff voting

class embedded_voting.RuleInstantRunoff(rule=None)

This class enables to extend a voting rule to an ordinal input with Instant Runoff ranking. You cannot access to the scores_ because IRV only compute the ranking of the candidates.

Parameters:rule (Rule) – The aggregation rule used to determine the aggregated scores of the candidates.

Examples

>>> ratings = np.array([[.1, .2, .8, 1], [.7, .9, .8, .6], [1, .6, .1, .3]])
>>> embeddings = Embeddings(np.array([[1, 0], [1, 1], [0, 1]]), norm=True)
>>> election = RuleInstantRunoff(RuleSVDNash())(ratings, embeddings)
>>> election.ranking_
[1, 0, 2, 3]
