题意: 田忌和齐王各有n匹马,如果马的速度比齐王的快就赢200,慢则输200,相等不赔不赚. 已知两人每匹马的速度(为整数)和齐王所排出的马的顺序,问田忌该如何应对才能使收益最大. 分析: 本以为是一道很简单的贪心,上来就贪,结果什么都没贪出来. 看了题解才发现贪心是比较复杂的. 这里贴上poj某牛的神分析. 贪心策略: 1,如果田忌的最快马快于齐王的最快马,则两者比. (因为若是田忌的别的马很可能就赢不了了,所以两者比) 2,如果田忌的最快马慢于齐王的最快马,则用田忌的最慢马和齐王的最快马比.…

思路:先按从小到大排序, 然后从最快的開始比(如果i, j 是最慢的一端, flag1, flag2是最快的一端 ),田的最快的大于king的 则比較,如果等于然后推断,有三种情况: 一:大于则比較,二等于在推断田的最慢的是不是比king的最快的慢,三小于则与king的最快的比較: Tian Ji -- The Horse Racing Time Limit: 2000/1000 MS (Java/Others)    Memory Limit: 65536/32768 K (Java/Othe…

题目 这道题主要是需要考虑到各种情况:先对马的速度进行排序,然后分情况考虑: 1.当田忌最慢的马比国王最慢的马快则赢一局 2.当田忌最快的马比国王最快的马快则赢一局 3.当田忌最快的马比国王最快的马慢 则用田忌最慢的马和国王最快的马比,输一局 4.当他们最快的马相等时则用 田忌最慢的马和国王最快的马比.[因为自己后面的队友很有可能战胜此时对方的这匹慢马,所以就算自己输一场,队友也能帮忙赢回一场,而胜一场,输一场的收益和打平一场的收益是一样的,而且自己输的时候可以拉对方最快的马下水,给己方最快的马…

Tian Ji -- The Horse Racing HDU - 1052 (有平局的田忌赛马,田忌赢一次得200块,输一次输掉200块,平局不得钱不输钱,要使得田忌得到最多(如果只能输就输的最少)) 首先,实际是要求两人马的配对关系.那么不妨设齐王是按从快到慢的顺序出马的.因此先将齐王的马排序. 关键在于田忌最慢的马,能先赢就先赢,不能赢就去消耗齐王最快的马,然后再来考虑最快的马,能先赢就先赢,不能赢说明现在田忌和齐王最快的马和最慢的马都相等,再来考虑把田忌最慢的马和齐王最快的马比较. 可以…

算法分析: 这个问题很显然可以转化成一个二分图最佳匹配的问题.把田忌的马放左边,把齐王的马放右边.田忌的马A和齐王的B之间,如果田忌的马胜,则连一条权为200的边:如果平局,则连一条权为0的边:如果输,则连一条权为-200的边. 然而我们知道,二分图的最佳匹配算法的复杂度很高,无法满足N＝2000的要求. 我们不妨用贪心思想来分析一下问题.因为田忌掌握有比赛的“主动权”,他总是根据齐王所出的马来分配自己的马,所以这里不妨认为齐王的出马顺序是按马的速度从高到低出的.由这样的假设,我们归纳出如下贪心…

自画像系列是梵高的代表作之一,他是一位自学成才的画家,下笔完全自由,主观提取了当时印象派画家学到的技巧,在这幅画中,我们可以看到,颜色在画中的堆叠,色彩与笔在画中表现的形态,都表现出,梵高在他作画中内心的状态,这幅作品是他不平静内心的真是写照,绘画不仅是梵高表达情感的方式,也是他和世界联系的唯一方式,他曾经说,希望所有人都能看到我的画,并能通过我的画感受到我的内心. 梵高的一生很少的照片,我们至今为止只能找到他的三张照片,而且还是21岁以前的,但在1885-1889年期间,他却以惊人的速度画了4…

题意:田忌和齐王有n匹马,进行n局比赛,每局比赛输者给胜者200,问田忌最多能得多少钱. 分析:如果田忌最下等的马比齐王最下等的马好,是没必要拿最下等的马和齐王最好的马比的.(最上等马同理) 因此,如果田忌最下等的马>齐王最下等的马或者田忌最上等的马>齐王最上等的马,直接得200,如果不满足该条件,那么才让田忌最下等的马与齐王最上等的马来比. #pragma comment(linker, "/STACK:102400000, 102400000") #include<…

思路:反状态压缩——把数据转换成20位的01来进行运算 因为只有20位,而且&,|,^都不会进位,那么一位一位地看,每一位不是0就是1,这样求出每一位是1的概率,再乘以该位的十进制数,累加,就得到了总体的期望. 对于每一位,状态转移方程如下: f[i][j]表示该位取前i个数,运算得到j(0或1)的概率是多少. f[i][1]=f[i-1][1]*p[i]+根据不同运算符和第i位的值运算得到1的概率. f[i][0]=f[i-1][0]*p[i]+根据不同运算符和第i位的值运算得到0的概率. 初…
