整体思想:还是基于MCTS为核心,然后基于学到的policy和value指导search;search根据N(s,a)输出一个policy\pi(a|s)结合游戏最终胜负z,更新网络参数,使v接近z,且p接近\pi(a|s),具体如下图,也很清晰 self-play self-play的动作都是由MCTS决定a_t \sim \pi_t,\pi(a|s)= \sim N(s,a)^{1/\tau}\sum...

“...a nice combination of a lot of really useful information, put together in a way that doesn’t make my brain leak.” Gareth Lewis, Project Leader, Lionhead Studios, Black & White 2 “Programming Game AI by Example is an excellent book for both the game programming neophyte, the int...
A Min-Max algorithm has been implemented which decides the depth of the search space the AI agent chooses to search before making the move against computer AI agent. The depth is a function of the current score and the amount of time left for the game to continue. The AI agent identifies...
Artificial intelligence has been used in many fields. Wang et al. proposed a new hybrid approach that used an ensemble data fluctuation network (DFN) and multiple artificial intelligence (AI) algorithms, which was called the DFN-AI model [1]. Majetta et al. described a method of generating ...
