### Owen Densmore & Steve Guerin: Modeling

Before the modeling class (afternoon the first day!) you should:

- Download the most recent versions of
*both*NetLogo and NetLogo 3D from http://ccl.northwestern.edu/netlogo/ - Run some of the Model Library examples for both NetLogo and NetLogo 3D:
- Start the application
- Click Model Library in the File menu, try these:
- NetLogo: Art > Diffusion Graphics
- NetLogo 3D: 3D > Sample Models > Raindrops 3D

Note: move the 3D raindrop world by click & drag - To run most of the models, click "Setup" then "Go"
- To see the code, click on the Procedures tab

- Start the application
- Finally, under the "Help" menu, click "User Manual" and explore!

Note: the url discussed in class is: http://backspaces.net/csss08 which contains the models.zip file, which in turn contains the commandcenter.rtf file we used to build our model. CSSS08Day1.pdf is the slide set used for the first half of the class.

### David Krakauer

Here is a link to the pdf of David's Lecture on Evolutionary Dynamics

### Mark Newman

Here is a link to the pdf of Mark's 4 lectures on Networks

### Tom Carter

Here is a link to a page with various background readings -- I'll be talking about some of this material, watch the wiki for days/times

## Week Two: Ecology/Evolution/Molecular Biology/Disordered Systems

### Aaron Clauset: MCMC for Simulation and Inference

Here is a pdf copy of Aaron's lecture notes

These three references cover a wide variety of details related to Markov chain Monte Carlo (MCMC) methods. The second and third are general references, written for physics and machine learning audiences. (The Newman and Barkema book should be available through the SFI Library.) The first shows an application of MCMC methods in the context of learning the large-scale structure of networks.

- "Hierarchical structure and the prediction of missing links in networks." Clauset, Moore and Newman.
*Nature***453**, 98-101 (2008). *Monte Carlo Methods in Statistical Physics.*Newman and Barkema. Oxford University Press (1999).- "An Introduction to MCMC for Machine Learning." Andrieu, de Freitas, Doucet and Jordan.
*Machine Learning***50**, 5-43 (2003).

### Jennifer Dunne: Foodwebs

Jennifer Dunne is a Research Fellow at the Santa Fe Institute, and is Co-Director of the Pacific Ecoinformatics and Computational Ecology Lab in Berkeley, CA. Dr. Dunne will lecture on ecological network structure and recommends the following article (Williams and Martinez, 2000) as a starting point for learning about such research. Her lectures will use this Nature paper as a jumping off point for discussing recent advances in research on food-web topology and robustness.

### Dan Stein: Quenched Disorder, Spin Glasses, and Complexity

This course is designed to introduce the participant to the study of systems with quenched disorder, which are fascinating systems in their own right but which also helped introduce many of the ideas and concepts that have become central to complexity studies. These ideas have found applications to problems from fields as diverse as biology, computer science, and economics, and we will explore some of these as well.

The course presupposes no prior knowledge of physics or statistical mechanics, and math will be kept to a minimum. If you'd like a flavor of some of the things we'll be discussing, you can take a look at D.L. Stein, ``Spin Glasses*, Scientific American v. 261, pp. 52--59 (1989). Despite the passage of time, many of the issues and questions discussed in that article remain open!*

For those who would like to access the subject on a more technical level (which is unnecessary for this course), here are some references:

K. Binder and A.P. Young, ``Spin Glasses*, Rev. Mod. Phys. v. 58, p. 801 (1986).*

M. Mezard, G. Parisi, and M. Virasoro, ``Spin Glass Theory and Beyond (World Scientific, 1986).

Spin Glasses and Biology, edited by D.L. Stein (World Scientific Publishing Co., Singapore, 1992)

J.A. Hertz and K.H. Fischer, ``Spin Glasses* (Cambridge, 1989).*

C.M. Newman and D.L. Stein, ``Topical Review: Ordering and Broken Symmetry in Short-Ranged Spin Glasses*, Journal of Physics: Condensed Matter 15, R1319--R1364 (2003).*

The last of these can be accessed from my * Web page *
