Self-organization in two-dimensional swarms
Jihad Touma, Amer Shreim, Leonid Klushin
We undertake a systematic numerical exploration of self-organized states in a deterministic model of interacting self-propelled particles in two dimensions. In the process, we iden…
Attractor and Basin Entropies of Random Boolean Networks Under Asynchronous Stochastic Update
Amer Shreim, Andrew Berdahl, Florian Greil +2
We introduce a numerical method to study random Boolean networks with asynchronous stochas- tic update. Each node in the network of states starts with equal occupation probability…
The Interacting Branching Process as a Simple Model of Innovation
Vishal Sood, Myléne Mathieu, Amer Shreim +2
We describe innovation in terms of a generalized branching process. Each new invention pairs with any existing one to produce a number of offspring, which is Poisson distributed wi…
Activity Dependent Branching Ratios in Stocks, Solar X-ray Flux, and the Bak-Tang-Wiesenfeld Sandpile Model
Elliot Martin, Amer Shreim, Maya Paczuski
We define an activity dependent branching ratio that allows comparison of different time series . The branching ratio is defined as . The random variabl…
Random sampling vs. exact enumeration of attractors in random Boolean networks
Andrew Berdahl, Amer Shreim, Vishal Sood +2
We clarify the effect different sampling methods and weighting schemes have on the statistics of attractors in ensembles of random Boolean networks (RBNs). We directly measure cycl…
Avalanches, branching ratios, and clustering of attractors in Random Boolean Networks and in the segment polarity network of \emph{Drosophila}
Andrew Berdahl, Amer Shreim, Vishal Sood +2
We discuss basic features of emergent complexity in dynamical systems far from equilibrium by focusing on the network structure of their state space. We start by measuring the dist…
