| Complex Systems Summer School 2012 |
CSSS participants come from a wide range of disciplines. Participants are encouraged to share their knowledge by organizing their own tutorials.
Also, please post requests for tutorials here.
Non-linear measures of correlation
I have been working on how to quantify the reciprocal interaction of time-series over time. I am using Recurrence Plots (http://www.recurrence-plot.tk/glance.php). If anybody is interested in discussing this method, I am willing to prepare a small tutorial on what recurrence plots are and how I have been using them.

Intro to Philosophy of Science
Hi All, I've heard some interest in having a more structured/rigorous intro to ideas in the philosophy of science. I'd be happy to briefly explain some of the classic theories as well as some more recent views due to, e.g. Bas Van Fraassen, James Ladyman, Nancy Cartwright, and we could have a small (moderated!) group discussion.

Python, Computational Mechanics, and Information Theory
There has been interest in more discussion on a number of topics, and so i'm offering to have evening discussions on them. please sign up below so that i can get a feel for the number of people who would be attending. also, please put a preference for what day it should be.
Python
Sign up below if you'd like an introduction to basic python programming. Python is a general purpose, very flexible and useful programming language. It is used pretty extensively in scientific computing.

Order Book Dynamics: Learn how to trade in 15min
--I'm happy to repeat this -just get in touch with me.--
If you are curious about how stocks trade and want to try your luck, I'll be going over some of the basics with a hands-on example.
Meet at 7.30pm in main lecture hall Thursday June 7th. Please make sure to bring your laptop.

Update
Hi guys
I guess the main lecture hall is free at 6.30 pm and so we can meet there. I have a small talk through the idea and then maybe we can try out getting bifurcation plots for one or two systems. I use software written in MATLAB for the demo but the idea can be implemented in any software.
Here's a link to the http://twr.cs.kuleuven.be//research/software/delay/notice.shtml. This software can handle systems with time delays and can be used to obtain the bifurcation behaviour.
(1) Please download the software DDE-BIFTOOL and unzip.
(2) Within the folder, you will find another zipped folder in small case ‘ddebiftool’. Please unzip this into a folder with the same name
(3) Add the location of the folder to the path of MATLAB. I have also sent out a mail with a zipped folder containing files to get a bifurcation plot for a Rijke tube system. Do let me know if anyone did not get this. See you there!

An easier way to get a bifurcation plot
Hey guys I have been working in the past in obtaining bifurcation plots for different physical systems. There's a better way to get these pictures instead of getting the evolution at every parameter value of interest. This is called numerical continuation and basically involves tracking a curve. I plan to give a informal talk on how to do this and maybe even a demo on applying this technique on 14th June at 6.30 pm. Do mail me if you are interested at iitm.priya@gmail.com or sign up below.

Using Tisean on R on OS X
first install TISEAN, like you've done already. Make sure R is up to date (v 2.15). you can try to install RTisean from CRAN
install.packages("RTisean"); library(RTisean); henon()
But me and Dave both got an error about some bad file name, something about con and something about a long path involving -Tmp- Solution:
remove.packages("RTisean")
restart R download this: http://cl.ly/0I0b2P2L311y1q0q0y0n install it, it changes line 74 of nativeTISEAN.R which has some problems with file handling If you are golden, then:
> henon()

A conceptual shell
One thing that I think has been missing from this course is an explicit set of concepts and tools which we can use to relate all of the talks we've been listening to. Last fall, two other graduates students and I taught a survey course on complexity. We put together the following document, which contains one-paragraph summaries of what we felt were the 20 most important concepts that comprised the field of complexity. These were the "glue" that we used to relate all of our lectures and workshops. Most of these will probably be familiar to you, but I think they serve as a nice, concise reference and may be helpful in tying all of this information overload together. One caveat: These are works in progress and are in alphabetical rather than any logical conceptual order.
