Title Attractors, statistics and fluctuations of the dynamics of the Schelling's model for social segregation Type
Year 2015 Publication European Physical Journal B Abbreviated Journal Eur. Phys. J. B
Volume 88 Issue 1 Pages 12 pp
Keywords
Abstract Statistical properties, fluctuations and probabilistic arguments are shown to explain the robust dynamics of the Schelling's social segregation model. With the aid of probability density functions we characterize the attractors for multiple external parameters and conditions. We discuss the role of the initial states and we show that, indeed, the system evolves towards well defined attractors. Finally, we provide probabilistic arguments to explain quantitatively the observed behavior.

Title Migration-induced transition in social structures: a view through the Sakoda model of social interactions Type
Year 2020 Publication Scientific Reports Abbreviated Journal Sci. Rep.
Volume 10 Issue 1 Pages 18338
Keywords
Abstract We study the dynamics of three populations evolving in a two-dimensional discrete grid according to rules of attraction, rejection, or indifference following the framework of the seminal model by Sakoda and we apply it to migration phenomena. An interesting feature of the Sakoda model is the existence of a Potts-like energy which, as a common principle, decreases as time passes by. Here we consider the evolution of two populations until stabilization, then, we perturb this attractor by the inclusion of a third arrival: the immigrants. We show the conditions under which this irruption does not alter significantly the previous attractor (a sociological morphostatic behaviour) or it is dramatically changed (morphogenetic behaviour). We observe empirically that for a morphostatic behaviour the energy decreases while for morphogenesis this energy increases, revealing an escalation of social tension.

Title Self-Organized Societies: On the Sakoda Model of Social Interactions Type
Year 2017 Publication Complexity Abbreviated Journal Complexity
Volume Issue Pages 16 pp
Keywords
Abstract We characterize the behavior and the social structures appearing from a model of general social interaction proposed by Sakoda. The model consists of two interacting populations in a two-dimensional periodic lattice with empty sites. It contemplates a set of simple rules that combine attitudes, ranges of interactions, and movement decisions. We analyze the evolution of the 45 different interaction rules via a Potts-like energy function which drives the system irreversibly to an equilibriumor a steady state. We discuss the robustness of the social structures, dynamical behaviors, and the existence of spatial long range order in terms of the social interactions and the equilibrium energy.
