Revision as of 12:31, 27 May 2010

I'm trying out some new skin on this wiki. Please feel free to tell whether you like it.


This is the page for the class Randomized Algorithms for the Spring 2010 semester. Students who take this class should check this page periodically for content updates and new announcements.

There is also a backup page for off-campus users. The URL is http://lamda.nju.edu.cn/yinyt/random2010wiki/

Announcement

  • (05/26/2010) 第十三课中的Estimator Theorem中有一处笔误,[math]\displaystyle{ \epsilon }[/math]应为[math]\displaystyle{ \epsilon^2 }[/math]。感谢钱超同学发现这个问题。
  • (05/25/2010) 第十三课的slides已上传。
  • (05/20/2010) 由于老师出差,本周officie hour推迟至周日下午。
  • (05/18/2010) The fourth homework assignment is out.
(older announcements...)

Syllabus

随机化(randomization)是现代计算机科学最重要的方法之一,近二十年来被广泛的应用于计算机科学的各个领域。在这些应用的背后,是一些共通的随机化原理。在随机算法这门课程中,我们将用数学的语言描述这些原理,将会介绍以下内容:

  • 一些重要的随机算法的设计思想和理论分析;
  • 概率论工具及其在算法分析中的应用,包括常用的概率不等式,以及数学证明的概率方法 (the probabilistic method);
  • 随机算法的概率模型,包括典型的随机算法模型,以及概率复杂度模型。

作为一门理论课程,这门课的内容偏重数学上的分析和证明。这么做的目的不单纯是为了追求严格性,而是因为用更聪明的方法去解决问题往往需要具备有一定深度的数学思维和数学洞察力。

先修课程 Prerequisites

  • 必须:离散数学,概率论。
  • 推荐:算法设计与分析。
