题目链接 思路:针对一个数组的操作,即对一个区间。可以用线段树去进行维护。初始化建树,叶子节点的值为1,维护每段区间上各个元素的乘积sum。M yi,将第i个元素的值改为yi。N di,将第di个元素的值改为1。输出即查询区间[1,Q]的sum值。也就是变成了单点更新、区间查询问题。 #includ Read More

简介限制理论(TOC)是美籍以色列人高德拉特(Eli Goldratt)博士从物理学领域引进到管理学领域形成的,它是Theory Of Constraints的简称,最初它作为一个物理学原理使用,一个简单的原理存在,它是指物理系统的最薄弱环节决定整个系统的产出或者效率,它在物理设计中经常使用到。1984年,高德拉特博士出版了他的第一本小说《目标》,书中运用约束的相关理论帮助一个工厂厂长在较短的时间

Unit 5 Queuing Theory
排队理论 排队理论是基于利特尔定律的
本章是理论与实践相结合的
从第五章开始是分水岭,第五章之前的都是监控,第五章开始都是调优
通过检测的数据利用理论来计算得出需要调优的方向与目标,最后用调优的方法去改善性能的状况
所有的调优都用队列技术,排队技术来解决问题
