==Moon solstice picnic - Saturday 22nd==

Friends of mine from Santa Fe have invited me for a hike & picnic Saturday evening, to watch the year's biggest moon rise on the hill behind st john's. They're very generous people, and when I told them about the school they insisted that I bring friends along. Since they'll cook and bring the food, I think I cannot reasonably invite more than 4 people though. Write your name and join us! (Meeting at 6:30pm at the fish pond) --Matteo

==Museum Hill - NOW Sunday 23rd==
Would anyone be interested in checking out some of the museums on "Museum Hill" near St. John's? The day is flexible, if people going to Tent Rocks are also interested.
Now going Sunday 11:30AM departure - it's within walking distance so anyone can come later as well.
Possible museums include:
Museum of International Folk Art, 
Museum of Indian Arts & Culture, 
Wheelwright Museum of the American Indian 
Here is some [http://www.santafenm.info/museums.htm more info about the museums].
Anyone interested? --Molly

I'm in. --David

I saw this a bit late...for anyone who did not go today (Saturday the 22nd), I think I will go Sunday (23rd) around noon, followed by a walk down into town. --rebecca

==Tent Rocks National Monument on Saturday 22nd==
I would like to propose a field trip next Saturday (the 22nd), to visit the [http://www.blm.gov/nm/st/en/prog/recreation/rio_puerco/kasha_katuwe_tent_rocks.html Tent Rocks National Monument], which should be a very beautiful place.

Please write your name here if you are interested, so that we can see how many cars we have to rent.

==June 21 Madrid to see Juniper's Brother's band and to dance with hippies==

My brother's band [http://www.reverbnation.com/toddandthefox Todd and the Fox] is playing at the Mine Shaft in Madrid on June 21. Madrid is a ridiculous hippy town and has some of the best people watching there is. To boot, my brother's band is awesome and we can dance and have a great time http://www.reverbnation.com/show/10280700 --Juniper

Thumbs up!! -- [[Luís_Seoane | Luíño]]

Sounds great to me!! -- [[Jody_Wright | Jody]]

Sounds fun! I'd love to go. -Molly

I'm in too! -- Kevin

Sounds good! -- Melinda

I'm in too! -- Elisa

I'm in too! -- Johannes

I guess we have to rent cars in order to get there. Anybody wants to organize this? -- Kerstin

I'm in too! -- Filipe

Sorry this is kind of far and my car is already full, so you all will need to self organize for this one. I'll probably get there around 8:30 or so and maybe eat at the [http://www.thehollarrestaurant.com/ Holler] before hand, it's really yummy fancy southern food --Juniper

Is anyone with a car planning to go to this concert tonight? If yes, would you be willing to volunteer spaces in your car here and people can sign up? [[Jody_Wright | Jody]]

==More Games!==

So... I was thinking it might be fun to have a second games night some time this week- either to catch up on the Mafia/werewolf game that we didn't have on Sunday, or perhaps some other game. Some of you may have encountered [[That Game]]... which is as always being updated and altered. If you missed out on the first round, or want to play again (or simply want a chance to watch JP dissolving in laughter) then come along.
As for Time/Place... Ummm... I feel like Thursday evening might be good, perhaps upstairs lower common room... but if other times/day/place suggested then that's good too.

==Bandelier Field Trip==

We're taking a trip to [http://www.nps.gov/band/index.htm Bandelier National Monument] on Saturday June 8th. Please visit the [[Bandelier 2013 | Bandelier Field Trip]] Page to sign up!

==More Hiking!==

Check the [[Complex Systems Summer School 2013-Hiking]] page to see current plans!

Didn't get enough hiking at Bandelier? Come hiking/camping with me! I plan on going on a long hike (all day, preferably 10+ miles) one of the next two weekends. I brought things for camping and would love to do that if there is interest and it is possible to rent tents/sleeping bags in town (or if people want to just sleep outside, also fun). If that is not really possible or people would rather just go for a single day that is great as well. I am open to a lot of different things, there is so much great hiking around Santa Fe!

Some suggestions:
* [http://www.backpacker.com/april_1999_destinations_new_mexico_pecos_wilderness/destinations/696 Pecos Wilderness] - just outside of Santa Fe, lots of trails!
* [http://www.summitpost.org/wheeler-peak-nm/150429 Wheeler Peak] - tallest mountain in New Mexico, outside of Taos (would require either camping at the base or waking up very early to do it the day of)
** Near Taos we can find these [https://www.google.com/maps/preview#!data=!4m18!3m17!1m1!1sSanta+Fe+Institute%2C+1399+Hyde+Park+Road%2C+Santa+Fe%2C+New+Mexico!1m5!1sManby+Hot+Springs!2s0x87177428acfba0e5%3A0x69769a1d19abcbff!3m2!3d36.5083168!4d-105.7242545!3m8!1m3!1d10957!2d-105.7242545!3d36.5083162!3m2!1i1366!2i656!4f13.1&fid=0 hotsprings]!!!!!!!
* [http://www.fodors.com/world/north-america/usa/new-mexico/taos/review-465844.html Carson National Forest] - North of Santa Fe, another beautiful forest, lots of different entrance locations

I am up for any other suggestions if people have heard of trails they want to go on. Depending on how the fires progress we may or may not be limited, but should be able to do something! Send me an email if you are interested and we can talk logistics (bstoll1234@gmail.com) [[Brady_Stoll|Brady]]

I would love to go! I had a hike in mind too--Tesuque Peak, which is just by the ski area and is 12 miles, but I am up for any of them! -Lauren (lash1937@gmail.com)

I'm interested! -Hua (caih@umich.edu)

I'm defintley interested - Wheeler Peak sounds very interesting (I have to get camping stuff though)! - johannes (johannes dot schmidt at boku dot ac dot at)

If we did Wheeler Peak, I am highly in favor of the longer class 1 route. The shorter class 2 route has a scree slope at the end, and I really dislike scree (it scares me). If we camped at the trailhead, I have a 3 person tent that we could use. --Lauren

If you'd like a similar experience to Wheeler Peak, but a lot closer, I recommend Santa Fe Baldy (12600'). Well above treeline, with fantastic vistas in all directions. The trailhead is only about 20 minutes away at the Santa Fe Ski Basin. The roundtrip hike is about 14 miles, making it a reasonable day hike. As always with any mountain around here, you need to be off the exposed sections by about 2PM because of the danger from thunderstorms! --John L

More hiking would rock!(Although I'm not sure about optimal length...) --Todd

==Music on the Hill==

St. John's hosts [http://www.stjohnscollege.edu/events/SF/music.shtml live music] on the soccer field this Wednesday (June 12) as well as next Wednesday (June 19) and the Wednesday after (June 26). Performances start around 6:00 PM. It looks like all of the performers will be doing jazz. I really hope to make the June 19 performance, as this will be big band, which is (usually) great for dancing. Any other swing dancers in our group? --[[Vanessa_Schweizer | Vanessa]]

* sounds fun to me! -- Hua
* I'm definitely interested! --Molly
* Sounds fun to me as welll! --Brady
* Sounds fun! --Jody

==Mafia/Werewolf==
[[JP]] LOVES to Play [http://en.wikipedia.org/wiki/Mafia_(party_game) Mafia/Werewolf]. Let's set up a time one of these evenings in the lower commons...

This sounds pretty cool. [[todd_bodnar | Todd]]

I like Mafia a lot, and I also brought a card game called [http://en.wikipedia.org/wiki/Fluxx Fluxx], and also know a few other games you can play with just paper and pencil (like [http://natsdistractions.wordpress.com/2009/12/13/great-party-game/ Bucket of Nouns]). I think a game night would be fun! --Molly

I would love to play Go if anyone is interested. --John D -- Count me in!! -- [[Luís_Seoane | Luíño]]

We should probably set a time/day/place if we actually want this to happen... I suggest 7:00am on sunday, with the lower common room thing, unless something else is happening then.

I like the game! Count me in! -- Hua

==Dance party==

Would anyone be interested in some sort of clubbing/dance party some time this month? And to be clear I don't mean going down to a bar to sit round drinking beers- that can be fun too, but I'm meaning something more music/dance focused.
If so,

What bars/clubs do people know of the might work? what music do they provide?

What music are people interested in? Remember, music that is good to listen to is not always good for dancing (and to be fair, there's plenty of music which is fun to dance to, but might not actually be "good")

Also, didn't someone mention some degree of DJing or music abilities? I can't remember, but if so, we could try to get our hands on the light rigs in the lecture hall and just make our own dance part from scratch...

*Our own dance party from scratch sounds fun to me. --[[Vanessa_Schweizer | Vanessa]]

So, some investigation indicates that hosting a large scale party at St Johns could be fairly impossible. She suggested hiring a venue in town... but I figure if that's the case we might as well just head down there and take it over by force of numbers.

*There is a CSSS "Dance with Breadloaf workshop" scheduled for June 22 starting at 8:00 PM. Is this an actual dance, or is this a complexity science thing??? --[[Vanessa_Schweizer | Vanessa]]

==Mountain Biking==

I would like to go mountain biking on sunday (9th of June). Anybody interested in joining me? We can rent a bike in the city for either 30$ (hard tail) or 60$(fully), helmets are 4$ extra. For those who are interested: please put your name and your height (needed for bike reservation) here until Thursday evening, I'm going to reserve the bikes then. [[Johannes_Schmidt]]

==Athletic Things==

I've heard lots of people talking about running/walking etc, and at dinner last night we mentioned that it would be fun to have a running group. Anyone interested in having a running/walking group either in the mornings or evenings? Post interest here!

I'm interested in a (quick) '''walking group''' in the mornings. It's great to exercise a bit in this nice weather and be able to talk at the same time. [[Regina_Martinez |Regina]]
*I would also be up for quick walking - whether we mean walking briskly or walking for 20-30 min. --[[Vanessa_Schweizer | Vanessa]]

Also, I love ultimate frisbee! Anyone interested in either learning or playing a game perhaps sunday or after dinner one day next week? Let me know! [[Brady_Stoll|Brady]]
*Ultimate would be fun, although I had a pretty bad knee injury years ago and haven't done that much running since then. I could see how long I would last. --[[Vanessa_Schweizer | Vanessa]]
*That's fine, anything would be fun, even just throwing/teaching people to throw! -Brady
* Down to play. Anything planned for today? - Bapu
* I don't have any specific plans today, but would love to either throw or teach if you're interested before the sun goes down. Play for sure tomorrow? Lets say tomorrow after dinner for those interested
*'''Lets play frisbee today! (Wed) Meet after dinner and we'll walk over to the fields, or meet us there!'''

Or basketball? Anybody want to play a pickup game?
-I would play a pick up game -Brady

==Yoga==

Anyone interested in '''yoga tomorrow (Sunday 9th) at 7pm?''' Some of us are going to [[http://www.santafecommunityyoga.org/index.php/classes2/schedule]]. We are meeting at 6:30pm. There is only one more space in Lauren's car. But, if there are more people interested, we can try to find a solution for the commute. [[Regina_Martinez | Regina]]

Hi Regina - I would be interested in joining you for yoga if there is still space. Please email me at [[jjwright49@me.com]] and let me know. Thanks! - [[Jody_Wright | Jody]]

Anyone want to go to yoga tomorrow (Tuesday the 11th) evening? We were thinking of going to Hatha yoga at 5:30, so leaving campus at 5:00. We'll go to dinner afterwards too. Send me an email (lash1937@gmail.com) if interested. [[Lauren_Shoemaker | Lauren]]

==Sightseeing Weekend==

Anyone interested in going on a weekend road trip? This could be more of an 'easy going' option to the hiking trip proposed above. I was thinking of maybe driving up to Taos and doing some whitewater rafting and general sightseeing. Let me know if you are interested or have any other ideas. I don't have a car but am able to drive...

- [[Ivana_Stankov | Ivana]]

==THERE IS A FOURTH WEEKEND!!==

If you, like me, believe that CSSS lives on after Saturday 29...

If you, like me, are hanging around because you can't leave this sacred piece of ground anymore...

If you, like me, believe this month is only the beginning of a life that wasn't before...

Then you believe on the forth weekend!! I know many of you will stay a few days after CSSS is over and it would be nice to organize ourselves soon. So, if we choose to go somewhere, say taking a flight, we could get cheaper prices, etc! Also we will be needing shelter after the 29th. This might be an urgent thing ;) Let's use this to organize ourselves! I post some ideas below that I've heard around these days. -- [[Luís_Seoane | Luíño]]

*Trip to the Gran Canyon?
*Camping in some national park?
*Trip to San Francisco?
*Trip to Las Vegas where we make up random couples and get married :?

I vote for Grand Canyon + San Francisco. I have my plane back home from Albuquerque on the 7th of July, so I am totally in for post school plans! -- Elisa

If you come to San Francisco, I can probably show you some cool places. --[[Nix_Barnett | Nix]]

==Indoor climbing/bouldering on saturday (22)==

Me (Oskar), Jian and Swahi are visiting the local climbing gym tomorrow. If you wanna try bouldering and maybe some rope climbing, we are leaving from the cafeteria at 10.00 after breakfast. If you feel like coming, you can email me at oskarxvi at gmail dot com (or just show up). We will visit the market and grap some lunch in town afterwards. See you!

Complex Systems Summer School 2013-Hiking

2013-06-12T21:02:35Z

Stepanova: /* Long one-day trippers */

We decided to go this weekend to the Pecos Wilderness and climb Santa Fe Baldy. One group with ~10 people is going to go Saturday mid-morning ish, do a day hike and camp that night. The other group is going to (likely) leave Sunday and meet the first group out there, and we'll climb Baldy together.

We have to be below tree line by 2-ish (sooner if it looks like a storm is brewing), so should get back by dinner time, or can decide to go to dinner somewhere else in town.

We need to rent probably 1 car (I will drive 5 people to camp, Lauren will drive 4-5 people to day hike, +1 car for camping), and rent tents and sleeping bags, plus one stove for cooking.

In order to finalise numbers and know how much equipment to rent, please sign up here in whatever category applies and indicate whether you need a sleeping bag/mat!

Stepanova:

We're thinking about co-evolving a network and an attacker agent to see which topologies emerge in the network and which strategies may be used by agents within the network to create that topology. The starting point of our idea was the question if networks containing nodes that are "too big too fail" may reduce the resilience if directed attacks against important nodes are performed against the network - or if the networks can in fact reorganize rapidly in case of the failure of a central node.

== Open Issues to be discussed ==

* Define a proper set of research questions: we should probably come up with some guiding research questions.
* Who is evolving? Agents or the Network? We have to decide if our basic building blocks that evolve are the nodes that apply different linking strategies (i.e. every agent has a genome representing linking strategies) or if the network itself evolves (i.e. the network configuration is the genome). The same applies to the attacker: is there one central attacker or do we have a group of attackers (which may cooperate)
* Fitness of Network components and attackers: we have to find a good fitness measure, which very much is connected with the definition of our evolving entities. If we decide that single nodes evolve, fitness of a single node in the network could be simply survival - and to survive, links to neighbours are necessary, e.g. to harvest energy from the network.
* Network aim: what is the main aim of the network? What is transported through the network and how is this related to the fitness of the network (or the nodes in the network)?
* Resource constraints: we could introduce a single resource, e.g. energy, that may be used either for consumption, for building links, or for transporting over these links.
* Genome: how does the genome of attackers and network (or network nodes) look like?
* Strategies for network components and attackers: which strategies may be implemented by the different agents?
* Real world examples: are there any real world examples we can relate to?

Some further questions on the table:

* Do we consider addition of new nodes? (it depends on the idea of network we have and if we consider it a closed or open system)
* Related to the question above, do we consider a fair process, I mean attacker destroys n links, the net replicates creating n new links? Or attacker can blow up nodes? How do we react? Creating as many links as the node degree?
* When does our evolution/attack finish? Do we set n moves that net and attacker can perform?
* Should we put game theory concepts into the picture? (It is a 2/multi player game) Is there a game theory expert in the group?

== Minutes of meeting 7th June ==

We have decided the following in today's meeting:

* Reference real-life example is terrorist vs CIA or mafia vs police situations.
* The attacker tries to fragment the network, the attacked tries to recostruct it.
* The network we are dealing with is at least in the first place to keep things simple:
- undirected

- unweighted

- no self links

- no duplicate links

* We start with a network already in place.
* The attacker has the whole info about the network.
* The attacked has local information (I guess we didn't finally agreed on it, isn't it?).
* Attack is on nodes, one node per iteration can be removed.
* Attacker has the goal to minimize hierarchy.
* Fitness metric: global reach (proxy for hierarchy).
* The network react to the attack on the node (that has a degree d) by: attaching a new node with degree 1 and creating (d-1) new links between existing nodes.
* The "game" finishes when the network is no more connected.

'''TODO: define the genetic algorithm, the strategy of the attacked since it has local information (or not?)'''

'''If I skipped something please add.'''

Sorry, I missed previous meeting. Thank you for the notes. I want to clarify last point for myself:
“Game finishes when network is no more connected”. Does it mean that to finish a game I need only one node that is fully isolated? (CIA willn’t agree that they should stop their fight with terrorists on this).
I was thinking of more realistic game: CIA goal is to destroy all nodes (especially if they know all network). And node is destroyed if it is attacked directly or if it got isolated. Game finishes when no nodes remain. All the rest of procedure – adding new node and re-linking nodes is the same

== Possible Tools ==

Java with [http://jung.sourceforge.net/ jung library]
Python with [http://networkx.github.io/ networkX]

Comment: I (Andrea) looked into networkX (we were mentioning it yesterday) a bit and all the metrics to anlyze and the generation of graphs seems to be there.

Viualization with [https://gephi.org/ gephi] ?

* Related to the question above, do we consider a fair process, I mean attacker destroys n links, the net replicates creating n new links? Or attacker can blow up nodes? How do we react? Creating as many links as the node degree?
* When does our evolution/attack finish? Do we set n moves that net and attacker can perform?
* Should we put game theory concepts into the picture? (It is a 2/multi player game) Is there a game theory expert in the group?

== Minutes of meeting 7th June ==

We have decided the following in today's meeting:

* Reference real-life example is terrorist vs CIA or mafia vs police situations.
* The attacker tries to fragment the network, the attacked tries to recostruct it.
* The network we are dealing with is at least in the first place to keep things simple:
- undirected

- unweighted

- no self links

- no duplicate links

* We start with a network already in place.
* The attacker has the whole info about the network.
* The attacked has local information (I guess we didn't finally agreed on it, isn't it?).
* Attack is on nodes, one node per iteration can be removed.
* Attacker has the goal to minimize hierarchy.
* Fitness metric: global reach (proxy for hierarchy).
* The network react to the attack on the node (that has a degree d) by: attaching a new node with degree 1 and creating (d-1) new links between existing nodes.
* The "game" finishes when the network is no more connected.

'''TODO: define the genetic algorithm, the strategy of the attacked since it has local information (or not?)'''

'''If I skipped something please add.'''

Sorry, I missed previous meeting. Thank you for the notes. I want to clarify some points for myself:
1) Suppose all your network are just 2 connected nodes. According to procedure: One is destroyed by attack. New one appears with degree 1, so it connects to the remaining one. And you again have 2 connected nodes. And it goes forever. So this is example of ideal sustainable network for us?

2)“Game finishes when network is no more connected”. Does it mean that to finish a game I need only one node that is fully isolated? (CIA willn’t agree that they should stop their fight with terrorists on this).
I was thinking of more realistic game: CIA goal is to destroy all nodes (especially if they know all network). And node is destroyed if it is attacked directly or if it got isolated. Game finishes when no nodes remain. All the rest of procedure – adding new node and re-linking nodes is the same

== Possible Tools ==

Java with [http://jung.sourceforge.net/ jung library]
Python with [http://networkx.github.io/ networkX]

Comment: I (Andrea) looked into networkX (we were mentioning it yesterday) a bit and all the metrics to anlyze and the generation of graphs seems to be there.

Viualization with [https://gephi.org/ gephi] ?

== Meetings ==
June 7th, 1h30pm

Next meeting is: Tuesday @ 15.00 (?) other suggestions?

Complex Systems Summer School 2013-Tutorials

2013-06-06T15:49:04Z

Stepanova:

{{Complex Systems Summer School 2013}}

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.

This is not a Tutorial! I [[Pablo_Galindo]] had nowhere else to post it! Its an article pointing out 15 mistakes that could sink your academic careers!
http://chronicle.com/article/Self-Sabotage-in-the-Academic/138875/

'''Bayesian Modeling'''
I'd love to attend tutorials on Bayesian Modeling. I will be happy if someone can give a series of tutorials on this topic. [[Reniel_Cabral | Ren]]

I would also be interested in this! -Brady

* I might be able to help with this, though likely in more of a discussion format, perhaps with some slides stolen from a colleague :) [[Nix_Barnett | Nix]]

* Thanks [[Nix_Barnett | Nix]]! Sure, I would love to have those slides and read it. [[Reniel_Cabral | Ren]]

'''Dynamics in Networks'''

I am very interested in learning about network dynamics. Anyone else interested in having a tutorial on that? [[Regina_Martinez | Regina]]

* I'm very experienced with hidden Markov models, which are a generalization of Markov chains. These are networks with a (potentially stochastic) dynamic. Maybe this would help! [[Nix_Barnett | Nix]]

'''Cross impact balances and Markov chains'''

For anyone who could not make the tutorial, [https://docs.google.com/file/d/0B_w3ogGtuejzVG1Ma2tKenN2QjQ/edit?usp=sharing here is a copy of the slides], which provide another way of interpreting [http://www.cross-impact.de/english/CIB_e_Alg.htm web pages explaining the CIB algorithm]. Note that from the cross-impact balance analysis web site, you can download the free software to play with CIB analysis yourself. I am also happy to talk more one-on-one if needed! --[[User:Vanessas|Vanessas]] 02:24, 6 June 2013 (UTC)

As part of brainstorming for a possible project, three of us have decided to do a tutorial on [http://arxiv.org/abs/0912.5352 cross-impact balances (CIB)] (delivered by [[Vanessa_Schweizer | Vanessa]]) and Markov chains (delivered by [[Alastair_Jamieson-lane | Alastair]] and [[Matteo_Smerlak | Matteo]]). We think these methods could be leveraged to research some interesting questions. All are invited to this tutorial regardless of their interest in contributing to a project using these methods. This tutorial will be Wed. June 5th at 4:00 PM in the large lecture hall. --[[Vanessa_Schweizer | Vanessa]] 
PS -- For those interested in examples of studies that have used CIB analysis, see this one on [http://iopscience.iop.org/1748-9326/7/4/044011/article century-long socioeconomic scenarios] or this abstract on a [http://link.springer.com/article/10.1007%2Fs10389-011-0473-8 qualitative model regarding obesity development and prevention].

'''Python (and MASON)'''

If anyone is interested, I'd be happy to organize and run/co-run a Python programming tutorial. If anyone needs agent-based models beyond what NetLogo can handle, I'd be happy to run a tutorial on the [http://cs.gmu.edu/~eclab/projects/mason/ MASON] framework. -- [[David_Masad]]

Although I've been programming in python, this is the first time I've heard of MASON. I'm interested in learning about your framework. -- [[Cheryl_Abundo]]

I'd very interest on such tutorials --[[Mauricio_Cantor]]

I would also be interested in something on python -Brady

'''Genetic Algorithms and Multi-Objective Optimization'''

I have seen many people interested in implementing GAs to evolve networks, which is something I have done for some of my research. I also worked with Multi-Objective Optimization (MOO), which is perfectly possible with GAs and has been around for a while; but it has not become so mainstream. I propose to make a brief tutorial of classic Genetic Algorithm vs. Multi-Objective Genetic Algorithm. Enough people interested? If we are a few of us, we could just meet up and I'll tell you the basics! -- [[Luís_Seoane | Luíño]]
I would be very interested! --[[Molly_King | Molly]]

Me too --[[Mauricio_Cantor]]
Me too --[[Elena_Stepanova | Elena]]

'''Nix's Bag O' Mathematical Tools'''

I'm planning on giving a number of tutorials to supplement Jim Crutchfield and I's lectures. The purpose of these should be to help you with your projects ( and encourage usage of our methods ;) ). I think it'd be cool for people to use this area to suggest topics to focus on. I started an empty bulleted list below. This will become more clear after we've given our lectures, but feel free to throw ideas out there when they come up. General topics might be: Information theory, time series analysis/modeling/prediction, symbolic dynamics (coarse-graining dynamical systems, i.e. what Liz Bradley discussed briefly), hidden Markov models, signal processing, bayesian inference, complexity measures, etc. [[Nix_Barnett | Nix]]
*Intro to information theory. There seems to be some interest in this. I'd be happy to give a tutorial, but I should note that it will be covered (at a rapid pace) in Jim Crutchfield's lecture. [[Nix_Barnett | Nix]]
