题意为给你若干个三次函数,以及每一个函数所分布的区间,由于每个函数的所有的系数都是整数,所以最后的函数在整数点处的值也是整数. 现在每次可以插入函数或者询问区间,现在要求每次询问区间后,所有的函数在这个区间的函数值的和. 其实一个函数在这个区间的分布,就可以看成是四个函数分别在这个区间分布了. 这样对于单一的函数,我们可以用线段树来维护了,每次查询和更新的操作都是在O(log(n))的复杂度内实现的. 注意不要写挫,另注:UVA的服务器真的很快,果断赞啊. #include <iostream>…

通过上一篇文章的介绍,我们已经基本了解了:Factor是组成PGM模型的基本要素:Factor之间的运算和推理是构建高维复杂PGM模型的基础.那么接下来,我们将重点理解,Factor之间的推理(Reasoning Patterns).Factor之间的推理分为以下几类: 1. Causal Reasoning , 因果推理: 2. Evidential Reasoning,证据推理: 3. Intercausal Reasoning 本文将详细描述上述三种推理模式. 一 Casual Reaso…
