八皇后问题的拓展，n皇后问题的深度优先算法，可以把结果以文件形式输出。N<=20-eight of the Queen's expansion, n depth of the Queen's priority algorithm, the results can be output in the form of a document. N

八皇后问题，可以推广到N皇后，在学校的实验课上做的，用回溯法-The eight queens problem can be generalized to the N-Queens in the experimental class of the school, with backtracking

optaplanner中的例子，只要一个运行命令，可以看到有皇后问题，课程安排，考试安排，机器推理，，，，医院床安排等例子，完全图像界面的例子，如果感兴趣可以去jboss的官网找源码-optaplanner the example, just a run command, you can see that there are queens problem, examples of curriculum, examination arrangements, machine reasoning,,,

运用递归算法实现了八皇后问题,基本思路借鉴于四皇后的实现,(Using a recursive algorithm to achieve the eight queens problem, the realization of the basic ideas for reference in the queen,)
