由于mex运算的值域与n同级,就可以从这方面入手。 我们从每个能力值pi向社团ci建边。 假如枚举的值为i,与增广路算法相似,如果i能再找到匹配,那么mex的值一定会大于i,否则就找到了mex运算的答案。 但如果是这样的话,外层需要枚举到d,内层要枚举到最大值V,再加上匈牙利算法的单次的时间复杂度O(m),就会使总时...
没有出现的最小的非负整数,想到二分图最大匹配,将能力值放在左部,社团编号放在右部。我不会删除边之后的二分图是怎么做的,于是反着加入这些学生。对于每一次暴力做,时间复杂度 O(Vdm),过不了这道题。 注意到加入学生时有一个性质,他只会使得这张图的匹配数增大,于是不用每一次加入学生时都重新做一遍,在...

只能匹配一次,这样我们可以通过匈牙利算法,依此匹配能力值 ,直到匹配失败,就是某一天的团队能力最大值。 接着我们发现d天的修改操作相当于d次删除二分图的边,如果删除了某个边之后,我们重新清空匹配情况,再次使用上面的贪心匹配过程,复杂度不太好计算,我觉得差不多是 的吧,这样显然不太可行。 反过来考虑,我们倒着...

The solutions that do work properly all rely on undocumented features: Some use platform-specific native Windows API in a mex-file (Jan Simon’s recentWindowAPIsubmission really pushes the limit in this and other regards). Alternately, we can easily use the platform-independentJavaFrame: ...

Amex Centurion Travel Lounge in MEX I decided to stay at the Sheraton Maria Isabel Hotel & Towers because it was closer to the Zona Rosa neighborhood which is a touristy destination packed with restaurants, bars, and nightlife. It’s considered the gay area of Mexico City, but there are pl...
