Function skillratings::trueskill::match_quality

pub fn match_quality(
    player_one: &TrueSkillRating,
    player_two: &TrueSkillRating,
    config: &TrueSkillConfig
) -> f64

Gets the quality of the match, which is equal to the probability that the match will end in a draw. The higher the Value, the better the quality of the match.

Takes in two players as TrueSkillRatings and returns the probability of a draw occurring as an f64 between 1.0 and 0.0.

Similar to match_quality_two_teams.

Examples

use skillratings::trueskill::{match_quality, TrueSkillConfig, TrueSkillRating};

let player_one = TrueSkillRating::new();
let player_two = TrueSkillRating::new();

let config = TrueSkillConfig::new();

let quality = match_quality(&player_one, &player_two, &config);

// According to TrueSkill, there is a 44.7% chance this match will end in a draw.
assert!(((quality * 1000.0).round() - 447.0).abs() < f64::EPSILON);
