…… 做了几天搜索= =…… 发现对BFS和DFS还有点了解…… DFS是深度优先，当它找到一条可行路时，就会一直往下走，直到找到目标。当找不到目标时，就返回上一次走的岔口。这就是回溯。BFS是宽度优先，它先找到与之临近的，即使这次搜索部分具有满足下一步行动的条件，它也不进行下一步搜索，而是等到第一次搜索全部结束时，才取出满足下一步行动的所有解，继续搜索，如此反复。(扫雷时触雷时雷的爆炸方式就是如此，也和石子扔入水中时产生的波纹一样。)这就造成了此种解法必然有最优解。所以在只求有解，不求最优时，DFS首当其冲，而具有最优解时，BFS应该先考虑…… 当然…… 类似于迷宫问题…… 应该用BFS，DFS会溢出…… 造成RE= =~……先写到这……?今天一题未做…… T_T?
