POJ.2251 Dungeon Master (三维BFS) 题意分析 你被困在一个3D地牢中且继续寻找最短路径逃生.地牢由立方体单位构成,立方体中不定会充满岩石.向上下前后左右移动一个单位需要一分钟.你不能对角线移动并且迷宫四周坚石环绕. 若能逃离,则输出逃离需要的最短时间,否则输出Trapped!. 与二维BFS的差别在于,多了一个上下两层.所以除了先后左右移动,还要有上下移动,对于每个位置,总共有6种移动方式,将6种移动方式种可行的每次塞进队列里面就好了. 依旧还要记录歩数.此题没什么大…

1棋盘问题 在一个给定形状的棋盘(形状可能是不规则的)上面摆放棋子,棋子没有区别.要求摆放时任意的两个棋子不能放在棋盘中的同一行或者同一列,请编程求解对于给定形状和大小的棋盘,摆放k个棋子的所有可行的摆放方案C. Input 输入含有多组测试数据. 每组数据的第一行是两个正整数,n k,用一个空格隔开,表示了将在一个n*n的矩阵内描述棋盘,以及摆放棋子的数目. n <= 8 , k <= n 当为-1 -1时表示输入结束. 随后的n行描述了棋盘的形状:每行有n个字符,其中 # 表示棋盘区域,…

个人心得:一开始用DFS弄了半天一直输出不了结果,后面发现并没有进行判断:好不容易能够得出答案,结果超时了,才发现原来要用BFS: 对于DFS: 从一个点开始模拟能走的所有步骤,注意边界条件,走到不能走时返回上一步继续循环:耗时比较大,主要要注意当前的动作 格式的话 void dfs(int step) { 判断边界 尝试每一种可能 { 注意标记: 继续下一步: } 返回 } BFS广度搜索,能够走得位置都走,将能到达的位置进入队列,当一个位置的所有动作完成时出队列,注意标志不改变,当队列为空时…

和迷宫问题区别不大,相比于POJ1321的棋盘问题,这里的BFS是三维的,即从4个方向变为6个方向. 用上队列的进出操作较为轻松. #include<iostream> #include<cstdio> #include<cstring> #include<queue> #include<algorithm> using namespace std; char map[35][35][35]; int vis[35][35][35]; int t…

对于深度优先算法,第一个直观的想法是只要是要求输出最短情况的详细步骤的题目基本上都要使用深度优先来解决.比较常见的题目类型比如寻路等,可以结合相关的经典算法进行分析. 常用步骤: 第一道题目:Dungeon Master  http://poj.org/problem?id=2251 Input The input consists of a number of dungeons. Each dungeon description starts with a line containing th…
