THUSC 2014

今年第3次来帝都打酱油了


day -1

在飞机和地铁上度过了一天,好累的说,晚上打有T恤的CF


day 0

由于读题障碍,打CF其实是今天发生的事情(A都看不懂还玩**啊)

写代码毕竟比读题简单一点,不过还是弱弱的只做了ABC,不过好多人的DEF都fst了?

大哥D打错一个字符于是抱枕没了(其实我D再写个100来行就过了对吧)

day 1

机试果断跪烂了,口述(hu)一下题面吧,还有各种,B的想法

T1:在所有满足f(tm*f(s))=s*f(t)m的方程中求出f(n)的最小值,显然f(1)=1不然后面就乱了,于是又有f(f(x))=x,而且f是积性函数(看样例猜的),题目本质是把几个数换一下,于是我把p换成最小的几个质数,好像有35分的样子(sone大哥秒出带花树orzorz,可惜没写出)

T2:7个点的斯坦纳树,1000000组测试数据。真是凶傻,我很sb地写了发斯坦纳树预计35分(发现斯坦纳树写起来还是挺愉悦的)

T3:一个超立方体上,每个点的权值每个时间点会向四周扩散,求T个时间点后每个点的权值,矩乘40分,不过利用超立方体性质(orzGY)矩乘部分可以做到n2logT,因为两点异或一下就可以转化为原点和某个点的关系了,好像很多分的样子,可惜没想到


day 2

等面试真是痛苦,尤其周围还是各种大爷在讨论他们是怎么A题的

听到的一些奇怪的东西:

T1:一般图的最大权匹配,利用题目性质貌似可以避开带花树

T2:类似插头DP的轮廓线状压DP,利用预处理加速

T3:听说是离散傅立叶变换

下午在报告厅听到“唐文斌 湖南”,整个人都不好了(怎么被卖到那么远去的)
