Accessors

matrix

get matrix(): Matrix<C>
Returns Matrix<C>
Inherited from MatrixScoreMethod.matrix
- Defined in classes/matrix-score-method.ts:21

Methods

canonicalRanking

canonicalRanking(): C[][]
Returns C[][]
Inherited from MatrixScoreMethod.canonicalRanking
- Defined in classes/method.ts:27

deTie

deTie(): C[][]
Returns C[][]
Inherited from MatrixScoreMethod.deTie
- Defined in classes/method.ts:54

iteratedRanking

iteratedRanking(): C[][]
Ranking built by repeated wins instead of the method's own full ranking: run the method, record the winning tier, then re-run it restricted to the remaining candidates for the next place, and so on.

Differs from ranking() whenever the method's full ranking disagrees with how it ranks subsets — e.g. instant runoff orders losers by elimination time, while iterating re-elects a winner at every place.

Returns C[][]
Inherited from MatrixScoreMethod.iteratedRanking
- Defined in classes/method.ts:50

ranking

ranking(): C[][]
Result of the vote. The first item lists the winners of the vote.

For example this ranking means that Bear wins, Sheep is second and Lion third [ [ 'Bear' ], [ 'Sheep' ], [ 'Lion' ] ]

Returns C[][]
Inherited from MatrixScoreMethod.ranking
- Defined in classes/score-method.ts:20

restrict

restrict<D extends string>(candidates: D[]): MatrixScoreMethod<D>
Return a new instance of the same method restricted to a subset of candidates.
Type Parameters
- D extends string
Parameters
- candidates: D[]
Returns MatrixScoreMethod<D>
Inherited from MatrixScoreMethod.restrict
- Defined in classes/matrix-score-method.ts:25

restrictRanking

restrictRanking<D extends string>(candidates: D[]): D[][]
Type Parameters
- D extends string
Parameters
- candidates: D[]
Returns D[][]
Inherited from MatrixScoreMethod.restrictRanking
- Defined in classes/method.ts:37

scores

scores(): ScoreObject<C>
Returns ScoreObject<C>
Overrides MatrixScoreMethod.scores
- Defined in methods/schulze/index.ts:52

strengths

strengths(): Matrix<C>
Strongest-path ("beatpath") strength between every ordered pair of candidates, after Floyd-Warshall — the matrix Schulze's win count is derived from.

Returns Matrix<C>
- Defined in methods/schulze/index.ts:45
