Preference Profile (COMSOC)

In COMSOC, a preference profile collects the preference rankings of all voters over the set of alternatives.

Formally, a preference profile is usually written as

$$R:=({\succ }_1,\dots ,{\succ }_n),$$

where each voter $v_i\in V$ has one ranking

$${\succ }_i$$

over the set of alternatives $C$.

Intuitively, $R$ is the full input of the election: it tells us how every voter ranks the alternatives.

Examples

Ballots in an election
