Revision as of 04:03, 8 June 2010
The Algorithms For Lunch Bunch
Mon/Thu @ 1pm (starting May 20)
Venue: the graphics annex
Contents |
Readings
- Lattice theory (from Birkhoff) and its applications in complexity, clustering, social choice theory, and more.
- Here is an online collection of lecture notes.
- Lattice theory course with a focus on CS applications
Schedule
| Date | Topic | Reading |
|---|---|---|
| May 20 | Posets | Chapter 1: nice proof of Dilworth's theorem - also look at the exercises. Useful discussion of representation of posets here. |
| May 24 | Lattices: definition, semilattices, complete lattices, closure systems | Chapter 2 (I'd like to understand the point of closure systems better) |
| May 27 | Distributive and modular lattices | Chapter 8; Chapter 9. And a question to ponder. Try not to get too distracted by the discussion of varieties and prime ideals in Chapter 8, since for finite lattices, this is all quite unnecessary. |
| Jun 7 | Modular lattices | Chapter 9 |
| Jun 21 |
Other Topics
Potential topics: (add your name to vote (as many topics as you like))
Current top choices (at least two votes)
- (Avishek, Chris, Piyush) algorithmic game theory (from this book)
- (Piyush, Avishek, Jeff, Josh) concentration inequalities for random variables
- (Jeff, Chris, Josh, Piyush) uncertainty in spatial data (We would follow a series of (mainly) recent papers spanning areas from Computational Geometry, databases, machine learning, to statistics. We would start with models and then move on to specific applications where they are used. We will encounter many interesting open questions. If I get more votes or upon request, I will sketch a paper list in more detail)
General topics
- (Chris) quantum computing (possibly from these notes)
Complexity Theory
- complexity theory fundamentals (almost surely from Luca Trevisan's ongoing class)
- (Suresh) geometric flip theory (mulmuley's work on P vs NP). I suspect we'd go with this paper and these videos (and the associated reading material)
- (Suresh) A complexity series: the unique games conjecture, quantum computations as shortest paths and classical and quantum lower bounds + QIP=PSPACE)
Analysis Tools
Geometry
- Geometric Approximations (full book)
- (Josh?) computational topology (Edelsbrunner/Harer WARNING: Valerio teaches this class)
