The algorithm itself is relatively simple and should be seen maybe more as a planning algorithm than a learning one.</p> <p>At a high level, how does MCTS work? Instead of exhaustively searching all possibilities, MCTS searches the state tree in a principled way that prioritises exploration of the most promising paths within that tree.</p>
