Allie,
an UCI compliant open source chess engine by Adam Treat, written in C++ using Qt, released under the terms of GPL version 3.
Allie is inspired by the seminal AlphaZero paper [1] and the Leela Chess Zero project - in particular it utilizes the same networks produced by Leela Chess, and replaces Lc0 with an own implementation of a PUCT Monte-Carlo tree search [2].
Contents
AllieStein
AllieStein is the combination of Allie with Leela's third party Leelenstein network [3] [4], which is trained by supervised learning feeding in games from CCRL, supported by SGDR (Stochastic Gradient Descent with Warm Restarts) [5] and GGT (full-matrix adaptive regularization) [6], using batch renormalization [7], and adding gradient noise [8].
