Example

use tools_2048::{Game, GameMove, GameState, GameResult};

// create a new game
let mut game: Game<4> = Game::new().unwrap();

// make a move
game.make_move(GameMove::Left);
game.make_move(GameMove::Right);
game.make_move(GameMove::Up);
game.make_move(GameMove::Down);

// find the best move and make it
game.make_move(game.find_best_move(10_000).unwrap());

assert_eq!(game.state(), GameState::InProgress);  // the game should still be in progress
assert_eq!(game.result(), GameResult::Pending);  // the result shouldn't be decided yet

The AI is based on the Monte Carlo algorithm, and uses parallelism to speed up the process. At depth of 10 000, AI achieves 1024 tile ~100% of the time, 2048 tile ~96% of the time, and 4096 tile ~65% of the time.
