NetLogo Model of Spatial Eviction in Attraction-Repulsion Opinion Dynamics (1.0.0)
A reproducible NetLogo implementation of a spatial attraction-repulsion opinion model with eviction-driven relocation. Agents interact locally, converge with similar neighbors, diverge from dissimilar neighbors, and may evict the most dissimilar neighbor to a random empty location. Parameter sweeps reveal transitions among extremist, mixed, and consensus regimes, with outputs including phase diagrams, opinion distributions, and Moran’s I. The model is intended to reproduce and extend results on how exclusion frequency changes polarization outcomes.
Release Notes
Initial public release of the NetLogo model for spatial eviction in attraction-repulsion opinion dynamics. The model implements local opinion interaction (attraction/repulsion), eviction-driven relocation, and reproducible outputs for key metrics (Var(o), f_extreme, Moran’s I), phase diagrams, and robustness analyses.
This release aligns with the revised manuscript and includes ODD-style documentation for reproducibility. Core findings reproducible with this code are the three regimes (extremist, mixed, consensus) and their dependence on eviction frequency and tolerance. Known scope limits: regular lattice topology, one-dimensional opinions, and random relocation destinations in the baseline setup.
