TicTacToe-play-with-bot-AlphaZero

Play TicTacToe-play-with-bot with AlphaZero Policy

Model Description

<!-- Provide a longer summary of what this model is. -->

This implementation applies AlphaZero to the OpenAI/Gym/Atari TicTacToe-play-with-bot environment using LightZero and DI-engine.

LightZero is an efficient, easy-to-understand open-source toolkit that merges Monte Carlo Tree Search (MCTS) with Deep Reinforcement Learning (RL), simplifying their integration for developers and researchers. More details are in paper LightZero: A Unified Benchmark for Monte Carlo Tree Search in General Sequential Decision Scenarios.
