Cow Bowling DescriptionThe 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: 7 3 8 8 1 0 2 7 …

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…
1.直接用递归函数计算状态转移方程,效率十分低下,可以考虑用递推方法,其实就是“正着推导,逆着计算” #include<iostream> #include<algorithm> using namespace std; #define maxn 1000+5 int n; int a[maxn][maxn]; int d[maxn][maxn]; int main(){ for(;cin>>n && n;){ memset(d,,sizeof(d));…
递归方法解决数塔问题 状态转移方程:d[i][j]=a[i][j]+max{d[i+1][j],d[i+1][j+1]} 注意:1\d[i][j]表示从i,j出发的最大总和;2\变界值设为0;3\递归变界为n;4\结果为d[1][1] #include<iostream> #include<algorithm> using namespace std; #define maxn 1000+5 int n; int a[maxn][maxn]; int d[maxn][maxn];…
