• 8皇后问题——回溯法、递归解决


    最近工作上不太顺,虽然做大数据,但是部门拉胯,现在已经成为了CRUD工程师,唉。

    开始重温Java了,学习韩顺平老大的Java培训课,总不能就这样拉跨下去吧。

    看到了8皇后问题,这个很经典的问题。

    八皇后问题是一个古老而又著名的问题,是学习回溯算法的一个经典案例。之前应该练习过,今天我们就一起来探究一下吧!

    时间退回到1848年,国际西洋棋棋手马克斯·贝瑟尔提出了这样的一个问题,

    在8×8格的国际象棋上摆放八个皇后,使其不能互相攻击,即任意两个皇后都不能处于同一行、同一列或同一斜线上,问一共有多少种摆法。

    用Java写了一个,解法在下面:

    public class EgihtQueue {
    	public static void main(String[] args) {
    		int num = 8;
    		int[][] map = new int[num][num];
    		// 给原始地图赋值为全0
    		for(int i = 0; i < map.length; i++){
    			for(int j = 0; j < map[i].length; j++){
    				map[i][j] = 0;
    			}
    		}
    		// 开始
    		MyTool myTool = new MyTool();
    		myTool.putQueue(map, 0);
     	}
    }
    
    class MyTool{
    	// 在类内设置一个全局变量用来做计数器
    	int count = 0;
    	
    	public void showQueue(int[][] map){
    		count++;
    		System.out.println("Situation :" + count);
    		for(int i = 0; i < map.length; i++){
    			for(int j = 0; j < map[i].length; j++){
    				System.out.print(map[i][j] + " ");
    			}
    			System.out.println();
    		}
    	}
    		
    	// 判断是否可以为皇后放置的位置
    	public boolean checkQueue(int[][] map, int row, int column){
    		// 判断列上是否有其他皇后,其他皇后只可能出现在该行的前面
    		for(int i = row - 1; i >= 0; i--){
    			if(map[i][column] == 1){
    				return false;
    			}
    		}
    		
    		// 一行只会有一个皇后,对于行来说不需要判断
    		
    		// 判断当前皇后摆放的左上部分是否存在其他皇后,行和列都要减小
    		for(int i = row - 1, j = column - 1; i >= 0 && j >= 0; i--, j--){
    			if(map[i][j] == 1){
    				return false;
    			}
    		}
    		
    		// 判断当前皇后摆放的右上角是否存在其他皇后,行要减小但是列要增加
    		for(int i = row - 1, j = column + 1; i >= 0 && j < map[i].length; i--, j++){
    			if(map[i][j] == 1){
    				return false;
    			}
    		}
    		return true;
    	}
    	
    	// 开始进行回溯来寻找放置皇后的位置
    	public void putQueue(int[][] map, int row){
    		// 从每个行开始,遍历每一个列,行已经 给了,列指针走动就好
    		for(int j = 0; j < map[row].length; j++){
    			if(checkQueue(map, row, j)){
    				// 如果当前位置可以为皇后放置的位置则置为1
    				map[row][j] = 1;
    				// 递归终止条件为行数到达最大,也就是找到了最后一个皇后
    				if(row == map.length - 1){
    					// 此时得到了一个8皇后的结果
    					showQueue(map);
    				}else{
    					// 如果行数没有达到最大,则进行递归,进行行增大
    					putQueue(map, row + 1);
    				}
    				// 如果当前位置不可以为皇后放置的位置则置为0,开始回溯,在对应行开始重新放置
    				map[row][j] = 0;
    			}
    		}
    	}
    }
    

     结果:
