Also consider batch elimination: if some batch of candidates can be eliminated that collectively have fewer votes than some other candidate. Example vote totals: 30 A 19 B 5 C 4 D 6 E. Because C, D, and E's collective 15 votes can't overtake B's 19 votes, all 3 can be eliminated at once without changing the result. |

See the [[Equal-ranking methods in IRV]] article. IRV can be done with equal ranking allowed. The two main ways of doing this are either fractional (split the voter's ballot equally between all of their highest-ranked candidates that are ranked equally (3 candidates ranked 1st each get 1/3rd of a vote)), or whole votes (give each highest-equally-ranked candidate one vote (3 candidates get 1 vote each and 3 votes total)). |
