Goban

Library to play with a rusty goban

Use the version > 5.0 because in a bug detecting dead stones and in Ko detection

Channel : stable

Only contains move generation, and rules there is no IA, neither front-end.

rust cargo features: - thread-safe # for using Arc instead of Rc. decrease perfs. - history # each game will have his all history so you can iterate over it. decrease perfs.

Thanks to some help in profiling and optimisation we can run a playout radomly of an entire game in 28ms (before it was 600ms) !

Exemple :

```{rust} use crate::goban::rules::; use crate::goban::rules::game::; use rand::seq::IteratorRandom;

let mut g = Game::new(GobanSizes::Nine, Rule::Chinese); let mut i = 35; while !g.over() && i != 0 { g.play( // legals return an iterator on (x,y) points g.legals() .choose(&mut rand::thread_rng()) .map(|point| Move::Play(point.0,point.1)) .unwrap()); i -= 1; println!("{}", g); } ```

```{bash} ┏┯┯┯┯┯┯┯┓ ┠┼┼┼┼┼┼┼┨ ┠┼┼┼┼┼┼┼┨ ┠┼┼┼┼┼┼┼┨ ┠┼┼┼┼┼┼┼┨ ┠┼┼┼┼┼┼┼┨ ┠┼┼┼┼┼┼┼┨ ○┼┼┼┼┼┼┼┨ ┗┷┷┷┷┷┷┷┛

etc... ```

What works

• Capturing stones
• Playing
• Passing
• Resigning
• Implementation to count points
• Printing an pretty unicode Board on the terminal !
• SGF Import
• Generate legals moves (Handling Ko detection, Suicide moves, Super ko)
• Japanese Rules
• Chinese Rules

What is not in point:

• Handling dead stones at the end of the game.

Actively developed

• Iterate over the game and history
