constructor

new AbsoluteMajority<C extends string>(
c: { ballots: Ballot<C>[]; candidates: C[]; unrankedLast?: boolean },
): AbsoluteMajority<C>
Type Parameters
- C extends string
Parameters
- c: { ballots: Ballot<C>[]; candidates: C[]; unrankedLast?: boolean }
  - ballots: Ballot<C>[]
  - candidates: C[]
  - OptionalunrankedLast?: boolean
    
    Whether candidates a ballot leaves unranked are appended to it as one tied bottom tier (default true — the classic "pessimistic" completion of partial ballots). Pass false to score only what voters expressed: unranked candidates then earn nothing from that ballot (no Borda points, no transfers, no last-place counts).

Accessors

matrix

get matrix(): Matrix<C>
Return a matrix of duels from all the ballots

Returns Matrix<C>
Inherited from BallotScoreMethod.matrix
- Defined in classes/ballot-method.ts:44

Methods

`Protected`ballotsFor

ballotsFor(candidates: C[]): Ballot<C>[]
The stored ballots re-normalized against a subset of candidates, honoring this method's unrankedLast setting. Round-based methods use this to restrict ballots to the candidates still in the running.
Parameters
- candidates: C[]
Returns Ballot<C>[]
Inherited from BallotScoreMethod.ballotsFor
- Defined in classes/ballot-method.ts:37

canonicalRanking

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

deTie

deTie(): C[][]
Returns C[][]
Inherited from BallotScoreMethod.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 BallotScoreMethod.iteratedRanking
- Defined in classes/method.ts:50

ranking

ranking(): C[][]
Returns C[][]
Overrides BallotScoreMethod.ranking
- Defined in methods/absolute-majority/index.ts:23

restrict

restrict<D extends string>(candidates: D[]): BallotMethod<D>
Return a new instance of the same method restricted to a subset of candidates. Ballots are filtered to remove candidates not in the subset; unranked candidates are NOT appended (preserves only opinions voters expressed).
Type Parameters
- D extends string
Parameters
- candidates: D[]
Returns BallotMethod<D>
Inherited from BallotScoreMethod.restrict
- Defined in classes/ballot-method.ts:54

restrictRanking

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

scores

scores(): ScoreObject<C>
Returns ScoreObject<C>
Overrides BallotScoreMethod.scores
- Defined in methods/absolute-majority/index.ts:19
