Rust-Oware-AI

A Rust implementation of an Oware AI. Using minimax algorithm, alphabeta pruning and move sorting.

The purpose of this project is to compare the performances to a similar project written with C++. I used crossbeam::scope for the multithreading aspect, and there is some unit tests for the board. This Rust version is apparently the faster one.

How to run :

cargo run --release

Performances

First move speed with four threads in this Rust version :

cargo run --release

The same move but in the C++ version (g++ -std=c++20 -Ofast *.cpp;./a.out):

g++ -std=c++20 -Ofast *.cpp

Conclusion

I did my best to write exactly the same algorithm between the two versions. Both of them are available on my github, do not hesitate to tell me if i made a mistake somewhere, making the implementation not fair. I'm a litte bit surprised to see the Rust version win over C++. That's great !
