Struct coliseum::env::rock_paper_scissors::RockPaperScissors

pub struct RockPaperScissors {
    pub rounds: u8,
    pub plays: Vec<(Option<u32>, Option<u32>)>,
    pub action_space: Discrete,
    pub observation_space: Discrete,
}

A simple two-player game, see https://en.wikipedia.org/wiki/Rock_paper_scissors

Fields

rounds: u8

plays: Vec<(Option<u32>, Option<u32>)>

action_space: Discrete

observation_space: Discrete

Methods

impl RockPaperScissors

pub fn default() -> RockPaperScissors

The default game is best out of 3, where possible action space is Rock, Paper, or Scissors. The observation space is the opponents last play

Trait Implementations

impl Environment<Discrete, u32, Discrete, u32> for RockPaperScissors

Examples

use coliseum::env;
use env::{Environment, State};
use env::rock_paper_scissors::RockPaperScissors;

let mut game = RockPaperScissors::default();
game.reset();

// our player loves rock
let agent = || 1;

loop {
    let State { reward, done, .. } = game.step(agent());

    if done {
        break;
    }
}

fn reset(&mut self) -> u32

fn step(&mut self, action: u32) -> State<u32>

Step takes an agent action and (probably) mutates itself; returns State to the agent.
