棋盘信息无疑会快于90个字节的棋盘,但这并不意味着所有的运算和操作都会更快。使用32个字节的数据表示,程序员在确定一个棋子的位置时往往需要增加额外的移位操作以取出一个字节中含有的两个坐标信息。2.2 比特棋盘(BitBoards)随着计算机存储能力的大幅提高,棋盘表示的空间需求往往已不是设计人员最为关注的问题。-chessboard information will undoubtedly faster than 90 bytes of chessboard. But this does not mean that all arithmetic operations and will be faster. Using 32 bytes of data, programmers in determining the location of a piece often need additional shift operation to remove a byte containing the 2 Coordinate information. 2.2 bits chessboard (BitBoards) with the computer storage capacity substantially higher. The board said the demand for space is not often designers most concern.
