New paper: Can Government Be Self-Organized? A Mathematical Model of the Collective Social Organization of Ancient Teotihuacan, Central Mexico

Teotihuacan was the first urban civilization of Mesoamerica and one of the largest of the ancient world. Following a tradition in archaeology to equate social complexity with centralized hierarchy, it is widely believed that the city’s origin and growth was controlled by a lineage of powerful individuals. However, much data is indicative of a government of co-rulers, and artistic traditions expressed an egalitarian ideology. Yet this alternative keeps being marginalized because the problems of collective action make it difficult to conceive how such a coalition could have functioned in principle. We therefore devised a mathematical model of the city’s hypothetical network of representatives as a formal proof of concept that widespread cooperation was realizable in a fully distributed manner. In the model, decisions become self-organized into globally optimal configurations even though local representatives behave and modify their relations in a rational and selfish manner. This self-optimization crucially depends on occasional communal interruptions of normal activity, and it is impeded when sections of the network are too independent. We relate these insights to theories about community-wide rituals at Teotihuacan and the city’s eventual disintegration.

The Past, Present and Future of Cybernetics and Systems Research

Summary of "The Past, Present and Future of Cybernetics and Systems Research" Symposium M at  European Meetings on Cybernetics and Systems Research (EMCSR), Vienna, Austria, April 12, 2012. Organizer: Carlos Gershenson This guided reflection on the challenges and opportunities of cybernetics and systems research (CSR) included initial interventions by panelists Peter Erdi, Helena Knyazeva, Stefan Thurner, Peter Csermely, and Alexander Lazlo. Afterwards, the floor was opened to interventions from the general public and further interventions by panelists. Commentaries were made from a broad variety of perspectives, but several general ideas can be distilled from the discussion. CSR have strongly influenced all scientific disciplines. As an example, the term "system" is used commonly in daily language. One of the breakthroughs of CSR lies in the search of commonalities across disciplines. Even when this was achieved to a certain degree, there is still a lack of

flocking memes...

Some ideas just came up, after a talk I had with Klaas , who is making a PhD on memetics... In cultural transmission of fads and so on, I've heard that there are models in which the majority imitates an elite, and the elite tries to go away from the crowd, and that gives you the dynamics... The idea is that maybe another way of looking at this phenomenon is to take the analogy of flocking: birds try to keep together (safety, direction, whatever reason), but also keep average distance to their neighbours (not to crash). If we take this mechanism into the memetic space, people will imitate many aspects surrounding them, just because of mirron neurons and the evolutionary advantage of imitation. But the separation is also important, for people assert their individuality with it... This could be seen as taking the inverse of a meme... starting to sounds like dialectics... (who would have thought that Hegel and starlings had lots in common...) Of course in the social context there are m

PhD thesis: "final" version online

After making several minor corrections, I have a "final" version of my thesis, which you can download here . I should defend it privately on April 20th, and if everything goes well, the public defense would be on May 2nd. Everybody's welcome! Design and Control of Self-organizing Systems PhD Dissertation presented by Carlos Gershenson Promoters: Prof. Dr. Bart D’Hooghe and Prof. Dr. Francis Heylighen Advisors: Prof. Dr. Bruce Edmonds Prof. Dr. Bernard Manderick Prof. Dr. Peter McBurney Prof. Dr. Ann Nowé Abstract Complex systems are usually difficult to design and control. There are several particular methods for coping with complexity, but there is no general approach to build complex systems. In this thesis I propose a methodology to aid engineers in the design and control of complex systems. This is based on the description of systems as self-organizing . Starting from the agent metaphor, the methodology proposes a conceptual framework and a se
