Function skillratings::egf::expected_score_rating_period

pub fn expected_score_rating_period(
    player: &EGFRating,
    opponents: &[(EGFRating, EGFConfig)]
) -> Vec<f64>

Calculates the expected outcome of a player in a rating period or tournament.

Takes in a players as EGFRating and a list of opponents as a slice of Tuples of EGFRatings and EGFConfigs and returns the probability of victory for each match as an Vec of f64 between 1.0 and 0.0 from the perspective of the player.
1.0 means a certain victory for the player, 0.0 means certain loss. Values near 0.5 mean a draw is likely to occur.

📌 Important note: The parameters intentionally work different from other expected_score_rating_period functions here.
In most cases the config is not used, however it is required here, because of the handicaps that can change from game-to-game.

Examples

use skillratings::egf::{expected_score_rating_period, EGFConfig, EGFRating};

let player = EGFRating { rating: 900.0 };

let opponent1 = (EGFRating { rating: 930.0 }, EGFConfig::new());

let opponent2 = (EGFRating { rating: 730.0 }, EGFConfig::new());

let exp = expected_score_rating_period(&player, &[opponent1, opponent2]);

assert_eq!((exp[0] * 100.0).round(), 48.0);
assert_eq!((exp[1] * 100.0).round(), 62.0);
