WebAs noted in the introduction, we require two modifications to the MCTS procedure: 1) a method to deal with continuous action spaces, and 2) a way to include a continuous policy network into the MCTS search. 3.1 Progressive Widening During MCTS with a discrete action space we evaluate the PUCT formula for all actions. However, WebMCTS is closely related with the so called multi-armed bandit problem. A K-armed bandit problem is defined as follows: We have K gambling machines (or actions in Markov Decision Processes) with the payoffs expressed using random variables Xin, for 1 iK and n 1, where i denotes the index of a gambling machine,

WebMonte Carlo Tree Search (MCTS) is a search method that combines the precision of tree search with the generality of random sampling. MCTS is used to find optimal decisions in a given domain by building a search tree according to explorations. MCTS contains 4 phases in one iteration, the selection phase, the expansion phase, the simulation phase ...
