N-Queen problem is a type of NP-hard problem, which aims at placing the queen in n*n chessboard in such a manner that no queen should kill another diagonally, horizontally and vertically. Earlier solutions have been provided using ACO (ant colony optimization), Genetic algorithm and DNA ...
Bit Operation for nQueen Problem 分析该算法时都是基于其二进制形式,其中, k记录当前已经放有皇后的列,1表示该列已经放有皇后了,0表示尚未放有皇后。 ld记录斜率为-1的方向上是否有皇后,1表示有,0表示没有。 rd记录斜率为1的方向上是否有皇后,1表示有,0表示没有。
