Formally, streaming algorithms treat the massively long input as a stream that provides only sequential access and aim to compute functions with a small local random-access working memory and very few passes over streams. There are various streaming settings using Read-Only or Read-Write streams and altering the following parameters: p total number of passes, s working memory size, t number of RW streams. Typically, p and t are constants, while s is also very small, e.g. polylog(n) or n^{0.1}. It is of great practical and theoretical interest to study the ability and limitations of different streaming settings. In this talk, I will present algorithms and impossibility results starting from the simplest single-stream setting to the involved multi-(RW)-stream setting. The talk is a tutorial introducing the basics of streaming computation with a slight bias towards topics I find most exciting. About the Speaker: Guang Yang is a graduating PhD student. He is reading computer science and mathematics at Andrew Yao's institute at Tsinghua University under the supervision of Periklis Papakonstantinou. His research interests are in the foundations of computer science and is intrigued by problems with immense practical motivation. Before he becomes a PhD student he did a Bachelors in Engineering at the Tsinghua's Elite CS class, aka Yao Class. He has received multiple distinctions as a PhD, undergraduate, and high-school student including a gold medal in CMO (China Mathematics Olympiad) for which he was offered direct admission the the undergraduate program in Tsinghua.
