摘要:

蒙特卡罗树搜索(MCTS)是文献中一种相对较新的多变量抽样方法。它们可以应用于各种具有挑战性的领域,包括棋盘游戏,视频游戏和基于能量的问题等等。在这项工作中,我们将探讨使用香草MCTS和MCTS与快速行动价值估计(MCTS-RAVE)在卡尔卡松,一个随机游戏的欺骗性评分系统,其中有限的研究已经进行了游戏。我们比较了基于MCTS的方法与Star2.5算法的优势,以前报道过在卡尔卡松游戏中产生竞争力的结果时,特定领域的启发式用于评估游戏状态。我们分析的特殊性时,他们共享一个共同的奖励系统的算法所采用的策略。基于MCTS的方法始终优于Star2.5算法,因为它们能够找到并遵循长期策略,其中香草MCTS表现出比MCTS-RAVE更强大的游戏性。

英文摘要:

Monte Carlo Tree Search (MCTS) is a relatively new sampling method with multiple variants in the literature. They can be applied to a wide variety of challenging domains including board games, video games, and energy-based problems to mention a few. In this work, we explore the use of the vanilla MCTS and the MCTS with Rapid Action Value Estimation (MCTS-RAVE) in the game of Carcassonne, a stochastic game with a deceptive scoring system where limited research has been conducted. We compare the strengths of the MCTS-based methods with the Star2.5 algorithm, previously reported to yield competitive results in the game of Carcassonne when a domain-specific heuristic is used to evaluate the game states. We analyse the particularities of the strategies adopted by the algorithms when they share a common reward system. The MCTS-based methods consistently outperformed the Star2.5 algorithm given their ability to find and follow long-term strategies, with the vanilla MCTS exhibiting a more robust game-play than the MCTS-RAVE.
