Today's Applied Complexity Symposium begins with a panel on Computation and Complex Economies, feat. Rob Axtell, Joshua Epstein, @C4COMPUTATION, Blake LeBaron, John Miller, & @MelMitchell1

(Follow this thread for live coverage all day...)

#complexsystems #economics
4 Principles of Collective #Computation:

1 Ground truth (objective reality)
2 Effective ground truth (what we agree on, whether or not it is accurate)
3 #Information can be collectively encoded in #networks
4 Outputs are a product of collective dynamics

"I think #economics really needs to adopt a generative framework with agent-based models of cognitively plausible software people...[and] we don't choose to fear."

SFI President David Krakauer introduces our annual board of trustees symposium on New #Complexity #Economics - follow this thread for live coverage of talks by @EricBeinhocker @AKStanger @ole_b_peters @JacksonmMatt @cmoncap & W. Brian Arthur today...
"I think we have to be aware that we're not just discussing financial systems. We are discussing the future of the stability of the planet."

on #Complexity #Economics
"What is the #economy? I would argue that it doesn't exist in the physical world. It is a product of our #imagination. It is made out of #ideas. It does have an effect on the physical world. But the imagined order that we have is not succeeding."

En mi tesis de magister estudiamos un modelo que relaciona la legitimidad (de la autoridad o del sistema político) con el descontento de la población. Así simulamos protestas sociales, donde la autoridad responde con el uso de la fuerza para restablecer el orden público. 1/13
Nuestro trabajo supone que el descontento se basa en la desigualdad de la distribución del dinero. Este modelo es una simplificación, que bajo suposiciones fenomenológicas, sirve para definir un marco y estudiar la complejidad de un proceso social, en este caso una protesta. 2/13
En el modelo las personas que tienen un descontento mayor deciden protestar corriendo el riesgo de ser capturados por la policía. Esto depende de la cantidad de policías en su entorno como también la cantidad de personas que están protestando. 3/13

"You don't see radio changing gradually and suddenly become radar. #Darwin's theory doesn't work for #technology, and we have to make a new observation."

"Novel technologies are constructed from existing technologies. These offer themselves as components for the construction of further technologies."

Unlike the two-parent #inheritance typical to (but not ubiquitous among) #complex organisms, #technology inherits features from n parents - a "vast ancestral #network" more like horizontal gene transfer networks in #bacteria.

"Life did not invent #DNA."

Experimental support for the #hotsprings hypothesis for life's origin: David Deamer of @ucsc on nucleic acid polymerization in the wet-dry cycling of Darwin's "warm little pond," powered by #geothermal. Lab results confirmed in #hydrothermal pools.
From "boring statistical partitioning" in the fission of early protocells to the complex #homeostasis-driven #mitosis of the cells we know - Doron Lancet of @WeizmannInstSci on the gradient between closure of #autocatalysis #networks to complex regulatory mechanisms of #biology.
"Life is an integrated nested network of dynamic #kinetic cycles."

Addy Pross emphasizes the importance of motion to the persistent forms of self-organizing #complexsystems at SFI today
