题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=4956(它放在题库后面的格式有一点点问题啦,所以就把它粘下来,方便读者观看) 题目意思:给出一个范围 [l, r] 你, 问是否能从中找到一个数证明 Hanamichi’s solution 的解法是错的. Hanamichi’s solution 是这样的: 对于某个数 X,从右往左数它的每一位数字(假设第一位是从0开始数).它 偶数位的数字之和 -  奇数位的数字之和  = 3  而且 这个 X…
基本数学题一道,看错位数,当成大数减做了,而且还把方向看反了.所求为最接近l的值. #include <cstdio> int f(__int64 x) { int i, sum; i = sum = ; while (x) { ) sum -= x%; else sum += x%; ++i; x/=; } return sum; } int main() { __int64 l, r, x; bool flg; int t; scanf("%d", &t); w…
解决暴力的直接方法.一个直接的推论x%11方法. 打表可以发现,以解决不同的情况都不会在很大程度上会出现. 所以从l暴力开始枚举.找到的第一个错误值输出要. 如果它超过r同样在美国发现-1. #include <iostream> #include <cstdlib> #include <cstring> #include <string> #include <cstdio> #include <cmath> #include <…

Poor Generalization 这可能是实际中遇到的最多问题. 比如FC网络为什么效果比CNN差那么多啊,是不是陷入局部最小值啊?是不是过拟合啊?是不是欠拟合啊? 在操场跑步的时候,又从SVM角度思考了一下,我认为Poor Generalization属于过拟合范畴. 与我的论文 [深度神经网络在面部情感分析系统中的应用与改良] 的观点一致. SVM ImageNet 2012上出现了一个经典虐杀场景.见[知乎专栏] 里面有一段这么说道: 当时,大多数的研究小组还都在用传统compute…
