Due to the complexity and length of the Monte Carlo Tree Search algorithm, it would be best to briefly explain how it works and refer you to an existing implementation. MCTS is an algorithm that uses random sampling and simulation to build a search tree and estimate action values. The algorithm consists of four main steps: Selection, Expansion, Simulation, and Backpropagation. The algorithm iteratively traverses the search tree, expands it by adding new nodes, simulates games, and updates the node values based on the outcomes of the simulations.
A good Python implementation of MCTS can be found here: https://github.com/pbsinclair42/MCTS
