Module wybr::methods::schulze

Schulze method

Schulze method expands the beat graph with widest beat-paths between candidates, and then attempts to find a Condorcet winner.

Examples

use wybr::{Tally,Schulze,Outcome};

//Load the Tennessee Wikipedia example
let tally=Tally::from_blt_file("examples/tennessee.blt").unwrap();

//Perform simple election with default parameters
let outcome=Schulze::new(&tally).run().unwrap();
assert_eq!(outcome.winner_name().unwrap(),"Nashville");

//Change pair score to `Margin`; this won't change the outcome, though
use wybr::PairScore;
let outcome=Schulze::new(&tally).pair_score(PairScore::Margin).run().unwrap();
assert_eq!(outcome.winner_name().unwrap(),"Nashville");
