Asynchrony induces polarization in attraction-based models of collective motion

Daniel Strömbom, Tasnia Hassan, W. Hunter Greis, Alice Antia
2019 Royal Society Open Science  
Here, we investigate the causal effects of this assumption in an attraction-only model and find that it has a dramatic impact.  ...  Given that many important models have been implemented with synchronous update only, we speculate that our understanding of the social interactions on which they are based may be incomplete.  ...  If this choice has an effect on this model, it is likely to have an effect on more sophisticated models, and as much of our current understanding of collective motion in moving animal groups is based on  ...

Anticipation Induces Polarized Collective Motion in Attraction Based Models

Daniel Strömbom, Lafayette College, Alice Antia, Carleton College
2021 Northeast Journal of Complex Systems  
We establish that anticipation induces polarized collective motion and inhibits swarming and milling in combination with attraction alone.  ...  Due to the biological plausibility of both attraction and anticipation we believe that utilizing these components to explain collective motion in animal groups may be advantageous in some cases.  ...  This is particularly surprising in the case of alignment-based models because the production of polarized collective motion is a key feature of models of this type, whereas production of mills and swarms  ...

Anticipation induces polarized collective motion in attraction based models [article]

Daniel Strömbom, Alice Antia
2017 arXiv   pre-print
In addition, unlike alignment based models the attraction based model used here does not produce any type of polarized collective motion in the absence of anticipation.  ...  Here we show that including anticipation induces polarized collective motion in a synchronous, off lattice, attraction based model.  ...  This is particularly surprising in the case of alignment based models because the production of polarized collective motion is a key feature of these models, whereas production of mills and swarms is not  ...

Attraction vs. Alignment as Drivers of Collective Motion

Daniel Strömbom, Grace Tulevech
2022 Frontiers in Applied Mathematics and Statistics  
These findings further challenge the current alignment based theory of collective motion and may contribute to a more versatile theory of collective motion across scales.  ...  In particular, via the use of self-propelled particle models it has been established that several other mechanisms induce group level alignment (aka polarization) in combination with attraction alone.  ...  a theory of collective motion based on explicit alignment interactions.  ...
