What is this?
A Go/weiqi/igo/baduk/goe engine written in Rust. (As should have been obvious from the punny name.)
How does it work?
Math.
What are the alternatives?
Searching for “Go” on crates.io gives roughly a bazillion hits, most of them not about the game. So far, I was able to unearth the following rivals:
They mostly seem to be unmaintained, though. (And they have less fun approaches to the necessary calculations.)
Anything else you want to say?
One day in the future I might write some useful documentation. Until then, feel free to e-mail me with questions. (Well, after then, too, but not before consulting the docs.)
