Crazy Shogi is an implementation of the AlphaZero algorithm, as published by DeepMind. It is entirely original code developed from scratch, in C++. The neural network code uses the cuDNN library to run on Nvidia GPUs. Crazy Shogi is part of the generic Crazy Zero system. Crazy Zero can also play chess, go, gomoku, renju, Othello, ataxx, breakthrough, kalah, twixt, and ultimate tic-tac-toe. In 2020, the neural network of Crazy Shogi will be trained thanks to computing power provided by the NVIDIA Inception Program.
