POJ 3176 Cow Bowling 题目简化即为从一个三角形数列的顶端沿对角线走到底端,所取得的和最大值 7 * 3 8 * 8 1 0 * 2 7 4 4 * 4 5 2 6 5 该走法即为最大值 分析:简单的动态规划,从上往下一层一层的考虑,对于每一行的最左边和最右边只有一种走法,只需要简单的相加, 对于中间的数要考虑是加上左上角的数还是加右上角的数,加上两者中的较大者 代码: #include<iostream> #include<cstdio> #include<…

题目链接:http://poj.org/problem?id=3176 思路分析:基本的DP题目:将每个节点视为一个状态,记为B[i][j], 状态转移方程为 B[i][j] = A[i][j] + Max( B[i+1][j], B[i+1][j+1] ); 代码如下: #include <stdio.h> + ; int A[MAX_N][MAX_N], B[MAX_N][MAX_N]; int Max( int a, int b ) { return a > b ? a : b;…

看题传送门门:http://poj.org/problem?id=1163 困死了....QAQ 普通做法,从下往上,可得状态转移方程为: dp[i][j]= a[i][j] + max (dp[i+1][j]  , dp[i+1][j+1] ); #include<cstdio> #include<cstring> int a[101][101]; int dp[101][101]; int main() { int n; while(~scanf("%d",…

Description The cows don't use actual bowling balls when they go bowling. They each take a number (in the range 0..99), though, and line up in a standard bowling-pin-like triangle like this: Then the other cows traverse the triangle starting from its…

动态规划:多阶段决策问题,每步求解的问题是后面阶段问题求解的子问题,每步决策将依赖于以前步骤的决策结果.(可以用于组合优化问题) 优化原则:一个最优决策序列的任何子序列本身一定是相当于子序列初始和结束状态的最优决策序列. 只有满足优化原则的问题才可以利用动态算法进行求解,因为只有全局最优解法等于其每个子问题的最优才可以分阶段进行求解. The cows don't use actual bowling balls when they go bowling. They each take a nu…
