電腦下象棋是如何程式設計的

　　象棋程式是讓人跟電腦下棋的，下面小編給你介紹，歡迎閱讀。

　　棋類遊戲一般都能建立起數學模型，電腦做的只是判斷這一步棋的下一步的每種可能走法，以及每種走法的下一步……以此類推，也就是說電腦能判斷下一步怎麼走，才能對自己在下下一步以致以後的多少步內都對自己有利。隨著電腦預測的步數的增加，計算量成指數級增加，計算時間也會更長，這樣，除了棋類程式的演算法因素以外，考驗的就是計算機的CPU計算速度了~所以要在電腦的“預測能力”和等待時間之間取一個折中的步數，比如20步。1997年IBM的“深藍”戰敗世界棋王卡西帕羅夫，就是因為他的計算機的計算能力是當時世界頂尖的。
