use shapley::{Coalition, Shapley};

fn main() {
    let players = vec![1, 2];
    let coalition_worth = HashMap::from([
        (Coalition::new(vec![]), 0.0),
        (Coalition::new(vec![1]), 10.0),
        (Coalition::new(vec![2]), 20.0),
        (Coalition::new(vec![1, 2]), 30.0),
    ]);
    let shapley = Shapley::new(players, coalition_worth);
    println!("player1: {}", shapley.shapley_value(1).unwrap());  // 10
    println!("player2: {}", shapley.shapley_value(2).unwrap());  // 20
