Complex Systems Summer School 2011-Projects & Working Groups

From Santa Fe Institute Events Wiki

Complex Systems Summer School 2011

If you'd like to work on a project with other members of the group, please use this page to organize your thoughts and efforts. We'll schedule a time when we can show off your work towards the end of the program.


Hey Guys! Some of your research interests have been entered. Hopefully this can give us a better idea of what we are studying, and how we can collaborate for the final challenge. They are organized in a google doc.

Hey Again! Here are two versions of the GML. The first is non-editable, it works. The second can be messed around with like a normal sharable google doc. Please remember to cut and paste ALL of the text (No bracket left behind!) into a text editor of your choice (like notepad) and save it as a .gml. There is a code called "value", this is so you can manipulate the PeopleNodes and the SubjectNodes as separate variables. If you have trouble, let me know. Again, apologies for misspellings and mis-placing-you-in-the-mega-universe-of-stuff-to-study.

They are organized in a google doc for sorting, searching etc, and all should have editing privileges. Sorry for typos!

Chaotic DJs

I'd like to play around with the idea of using chaotic attractors to create music, as introduced by Liz Bradley. If anyone else is interested, please say so below! Ideally, I'd love to create a new piece of music (perhaps even recording a few of the budding musicians at the summer school if possible!), pull the individual parts of the composition apart and then use chaotic attractors to put them back together in new (and constantly evolving) ways. I have music production software on my laptop that we can use as a backbone, but we'd need to work out how to program something so that the differential equations controlled it (or otherwise figure out how to use the DEs to make a composition that we then record within the software - perhaps an easier option!) I'd like to hear other people's ideas about what elements of the piece the chaotic attractors could be used to manipulate - Liz's example only used them to re-order pitch, but I'm sure there are other things that we could do too. Hopefully this could be a project that we could play with in our spare time - I'm also looking to join in with a more academic project too, but I think this could potentially be a very enjoyable side-project. -Martin Gould

How about having a quick meeting to discuss ideas on Thursday lunch time? Dining hall at noon? The original paper that Liz talked about is here: [1] perhaps we could discuss which of the original ideas we'd like to use and also brainstorm some new ones that we'd like to try out. -Martin

A Page for Mysterious Things
In other words, it's the talk page for members of this group. It's not exciting, don't look at it.

The CSSS11-network challenge

Discussing ongoing and new ideas for analysis. Mainly focussed on using current available data. Discussion in canteen, just find me (Evelien).

General Idea Project
We have by now quiet some data. Anyone interested can download the below files, and play around. Just let me know, and I will keep the overview here. At the end, all studies combine to one study of our network.

Current Questions (People working in will be entered before question, feel free to add questions)
- Is there interaction between people from different disciplines?
- Is the interaction correlated to the country of residence of participants?
- To what extend is there a correlation between external factors (first people met, location of dorm) and contacts?
- How do the contacts of a person evolve over time?
- Do we have 'hubs', and can we explain why these people have become hubs from either internal factors (nr of contacts) or external factors (type of person/area of research/...)
- What does a graphical study of our network tell us?
- What are statistical properties of our network?

Files:<\br> Will appear soon, whenever I have made my peace with R again...

File:DataS1 22June.xlsx
If you need more explanation, let me (Evelien) know.

Coming Tuesday, 20 minutes after the lectures end*, I will organize a get together on this project. Everyone interested, please feel welcome. I will announce the location later, here.
Please, do the following three things:

1) If you are interested in the analysis, if you have not yet done so, please feel in the survey (we need data!)
2) Think about what kind of thing you want to bring to this group: passive discussion/knowledge, or active ideas, hands on data analysis, and such
3) In the latter case of active participation, formulate your ideas in a less-than-5-minute (without slides) old fashioned talk/reasoning

We will have approx. 5 min idea-statements followed by approx. 5 minute positive, constructive discussion (this will be like a brainstorm session, so all ideas are welcome).
After we have heard all ideas, the people who want to actively participate will be strongly involved in making a practical schedule. I plan to have a first (anonymous) data-set available on Tuesday, if I’m lucky, before that.

  • I know that this will coincide with the individual talks of us, which are really interesting, too. The schedule with the labs, evening lectures, and so on, is just too full to do anything else. If you now have a double appointment, one solution is always to (convince your favorite speaker) to present in the last week.

Thank you for all your help and looking forward to Tuesday!


We might need some help with getting the data into a nice structure and such. If converting excel files to graphs is something you like to do, please drop me an email.

About the project
Today the Networks Module has started. One of the well-known examples of a network, is a social network. Did you realize you have been working hard on an (almost) completely new social network in the past few days?

How do these networks come in to place? How do we make friends? Will we be a fully connected network? How many hubs do we have - and can we explain how these hubs come in to place?

This is an excellent opportunity to find some answers to these questions!

The idea is to base the results on the contacts people make. Simply put: who did you have a conversation with? By noting this regularly, we can see the connectedness and sorts of the network evolve over time.

The plan is to collect data on
1) The evolvement of the network over time, in terms of nr of contacts (conversations lasting over 10 minutes) per approx. 2 days
2) The 'final' network, as in the people you feel connected to (would like to contact for science or social activities)

All results will be processed anonymously and will appear (at the end of the summerschool) on the wiki.

We need your help off course, to answer these questions.
The first survey can be found at:

If you are interested in this project, I will organize some discussion meeting (probably in the next week). For now: add your name to the list below, and send in the survey! (while encouraging as much of your connections as you can to do so, too ;) )

If you have any questions, send a message to ehuk at rsm dot nl.

Thank you so much for your help!

Econophysics/Economics Working Group

Akira, Veronica and I have been discussing some econophysics-type problems recently, and we are going to set up a small working group to meet and discuss our work and problems that we've been thinking about. We will be talking about using ideas from complex systems (such as agent-based modelling, statistical mechanics, etc.) to re-visit traditional problems from economics. We haven't set a date for our first meeting yet, but it's likely to be early next week. Please add your name to the list below if you'd like to come along, either to talk or just to listen!

I've had a chat with a couple of people today, and it seems like Monday 28th of June at 6pm could work for most people. Would people be interested in trying out something a bit old-school: a blackboard session? We see lots of Powerpoint presentations every day, so I thought this might mix things up a bit. For those of us that want to speak (and it's completely fine if you'd like to come along and just listen), we could take it in turns either presenting some of our research or discussing a problem that we're facing in our work, and want some ideas on. I think if we could keep it discussion-group style, this could be an excellent way of generating interdisciplinary ideas for everyone. - Martin

Complex Systems App

Would anyone be interested in teaming up to develop a complex systems-themed app for iPhone or iPad? The idea is inspired by NSF's gorgeous Science360 app for iPad, as well as Movies Mobile from the New England Complex Systems Institute.

I, myself, do not know how to write an app, but apparently it can be done in 14 days. If anyone is interested, sign up (with a concept if you have one) and we can pull together a meeting soon.

Collaboration Networks ABM

Would someone be interested in creating an agent based model for a collaboration network which could be applied to interdisciplinary research, or departments in a company, or any other other network where people from various backgrounds come together to solve a problem. I would like to model how such interdisciplinary work strengthens networks and promotes innovation, and also what the optimal conditions for that to happen are.

Please email me if you are interested and we can get together to discuss the details.
