电脑下象棋是如何程式设计的？

象棋程式是让乎耐人跟电脑下棋的，下面我给你介绍，欢迎阅读。

棋类游戏一般都能建立起数学模型，电脑做的只是判断这一步棋的下一岁态春步的每种可能走法，以及每种走法的下一步……以此类推，也就是说电脑能判断下一步怎么走，才能对自己在下下一步以致以后的多少步内都对自己有利。随着电脑预测的步数的增加，计算量成指数级增加，计算时间也会更长，这闭租样，除了棋类程式的演算法因素以外，考验的就是计算机的CPU计算速度了~所以要在电脑的“预测能力”和等待时间之间取一个折中的步数，比如20步。1997年IBM的“深蓝”战败世界棋王卡西帕罗夫，就是因为他的计算机的计算能力是当时世界顶尖的。

该游戏基于Bitboard设计，棋力高超稳定，曾荣获2005年第十届奥林匹克中国象棋电脑软件大赛冠军。

《象棋奇兵》在推出3.6免费版试用获得不错反响后，于2004年发布了象棋奇兵1.01版开始进行商业化，面向市场渗岁樱进行发售，此后又陆续发布了1.02、1.04、2.2、2.3、2.4、3.0、4.0、5.0、6.0等多个版本。

从1.02版本开始，象棋奇兵推出了高级版本，开始支持多线程运算，是为象棋软件开先河，其高超的棋力、全雀困面的功能受到棋友的广泛好评。

该软件的主要功能：

1、棋谱研究。能够读取pgn、xqn等不同格式的中国象棋棋谱文件，可以方便的丛丛进行打谱研究。支持棋谱和局面剪切板 *** 作。

2、人机对战。具有很强的人工智能，方便灵活的时间设置和强大的棋步分析功能。

3、摆设残局。方便快捷的残局摆设功能，丰富的快捷键，轻松实现让子和让先对弈的功能。

4、网络对战。内置弈天网站自动对弈功能，可以连接到弈天网站进行自动对弈。同时利用“弈星”象棋连线程序，能够让本软件连接到任何象棋网站进行自动对弈。
