Allie is a chess engine heavily inspired by the seminal AlphaZero paper and the Lc0 project.
Like Leela, Allie is based off of the same concepts and algorithms that were introduced by Deepmind in the AlphaZero paper(s), but her code is original and contains an alternative implementation of those ideas. You can think of Allie as a young cousin of Leela that utilizes the same networks produced by the Lc0 project.
