题目 简单的dp,但是我还是参考了网上的思路,具体我没考虑到的地方见代码 #include<stdio.h> #include<iostream> #include<string.h> #include<algorithm> using namespace std; #define inf 2100000000 //int min(int a,int b) //{ // return a<b? a:b; //} int main() { int t,i…

一共有N段过程,每段过程里可以选择 快速跑. 匀速跑 和 慢速跑 对于快速跑会消耗F1 的能量, 慢速跑会集聚F2的能量 选手一开始有M的能量,即能量上限 求通过全程的最短时间 定义DP[i][j] 为跨越第 i 个栏,剩余 j 点能量 动态转移方程 dp[i][j] = min(dp[i][j], dp[i-1][j-F1]+T1) (Fast Mode) dp[i][j] = min(dp[i][j], dp[i-1][j]+T2) (Normal Mode) dp[i][j] = min(…

题目:110米栏,运动员能够用三种状态跑,1状态耗体力且跑得快,2状态不消耗体力,3状态恢复体力且跑得慢. 体力上限是M,且初始满体力,如今想知到最小的时间跑全然程. 分析:dp,全然背包.题目是一个物品体积可能为负数的背包,求背包就可以. 只是,由于物品体积可能是负数,所以无论哪个方向背包都有后效性,直接用二维避免后效性. 转移方程:F(i,j)= min(F(i-F1,j)+ T1,F(i-1,j)+ T2,F(i+F2,j)+T3). 说明:(2011-09-19 01:23). #inc…

描述 假设字符串的基本操作仅为:删除一个字符.插入一个字符和将一个字符修改成另一个字符这三种操作. 我们把进行了一次上述三种操作的任意一种操作称为进行了一步字符基本操作. 下面我们定义两个字符串的编辑距离:对于两个字符串a和b,通过上述的基本操作,我们可以把a变成b或b变成a,那么字符串a变成字符串b需要的最少基本字符操作步数称为字符串a和字符串b的编辑距离. 例如:a="ABC",b="CBCD",则a与b的编辑距离为2. 你的任务就是:编一个快速的程序来计算任意…
