In computer science, Monte Carlo tree search ( MCTS) is a heuristic search algorithm for some kinds of decision processes, most notably those employed in software that plays board games. In that context MCTS is used to solve the game tree . MCTS was combined with neural networks in 2016 [1] and has been used in multiple …
Web是的,其实AlphaZero的核心真不是网络,是MCTS。 网络的作用是辅助MCTS。 或者说,用网络去 保存 (或者 拟合 )MCTS中,每个动作节点的Q和P。 这就有点像我们在学DQN的时候,就是用网络去保存Qtable里面的Q值一样。 只不过在AlphaZero里,我们的神经网络不是去保存一个表格,而是保存一棵树而已。 纯MCTS在开始使用的时候,会使用平均策 … WebAlphaGo Zero用到的技术,究其本质,是使用神经网络模拟蒙特卡洛树搜索(MCTS)的行为。 不过,MCTS也并不是总能找到最优解,所以神经网络需要进行70万轮对MCTS的模 …
