题意:在 H * W 的地图里有 N 个工厂,每个工厂分别生产硬度为1-N 的奶酪,有一只老鼠准备把所有奶酪都吃完.老鼠的初始体力值为1,每吃一个奶酪体力值加 1.已知老鼠不能吃硬度大于当前体力值的奶酪,老鼠只能向上下左右四个方向走,求吃完所有奶酪老鼠需要经过的最小步数. 分析:简单迷宫问题.不同的是,老鼠需要按1-N 的顺序把奶酪吃完.用广度优先搜索很容易求出起点到终点的最小步数.初始时,求起点到硬度值为 1 的奶酪的最小步数:接着将起点重置为此位置,继续求此位置到达硬度值为 2 的奶酪:如此…
题意:网格图,老鼠吃奶酪,吃完奶酪体力值会增加,只能吃硬度不大于体力值的,问最小步数. 思路:按硬度从小到大的吃起,依次求最短路. 我用曼哈顿距离估价的A*,和普通bfs的time没区别啊,还把优先级那里写错了... #include<bits/stdc++.h> using namespace std; #define PS push #define PB push_back #define MP make_pair #define fi first #define se second co…

原题链接 题目大意:FM在一个街道n*n街道的(0,0)点,在每个网格里放着cheese,他要尽可能多的吃这些cheese.有两个规则:1)他跑的总距离不能超过k步:2)下一个节点的cheese的块数必须超过这个节点. 解法:题目是去年秋天做的,现在看了下貌似就是用一下广搜,从原点开始一个个查找.我直接把当时的代码贴过来了,看看当时写的注释,发现暑假都过了一半了,算法都没有总结好.惭愧了. 参考代码: #include<string.h> using namespace std; int n,…
