篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了java围棋对弈实例相关的知识，希望对你有一定的参考价值。
围棋作为一个棋类竞技运动，在民间十分流行，为了熟悉围棋规则及技巧，以及研究简单的人工智能，决定用Java开发围棋游戏。主要完成了人机对战和玩家之间联网对战2个功能。网络连接部分为Socket编程应用，客户端和服务器端的交互用Class Message定义，有很好的可扩展性，客户端负责界面维护和收集用户输入的信息，及错误处理。服务器维护在线用户的基本信息和任意两个对战用户的棋盘信息，动态维护用户列表。在人机对弈中通过深度搜索和估值模块，来提高电脑棋手的智能。分析估值模块中的影响精准性的几个要素，以及提出若干提高精准性的办法，以及对它们搜索的节点数进行比较，在这些算法的基础上分析一些提高电脑AI方案，如递归算法、电脑学习等。算法的研究有助于理解程序结构，增强逻辑思维能力，在其他人工智能方面也有很大的参考作用。
直接上代码啦，let’s go
