Effects of heterogeneous social interactions on flocking dynamics
Social relationships characterize the interactions that occur within social species and may
have an important impact on collective animal motion. Here, we consider a variation of the …

Randomness in the choice of neighbours promotes cohesion in mobile animal groups
Classic computational models of collective motion suggest that simple local averaging rules
can promote many observed group-level patterns. Recent studies, however, suggest that …

Complex network structure of flocks in the Standard Vicsek Model
In flocking models, the collective motion of self-driven individuals leads to the formation of
complex spatiotemporal patterns. The Standard Vicsek Model (SVM) considers individuals …

Interaction ruling animal collective behavior depends on topological rather than metric distance: Evidence from a field study
M Ballerini, N Cabibbo, R Candelier… - Proceedings of the …, 2008 - National Acad Sciences
Numerical models indicate that collective animal behavior may emerge from simple local
rules of interaction among the individuals. However, very little is known about the nature of …
