Collective decision-making with heterogeneous biases: Role of network topology and susceptibility
Yunus Sevinchan, Petro Sarkanych, Abi Tenenbaum +2
The ability of groups to make accurate collective decisions depends on a complex interplay of various factors, such as prior information, biases, social influence, and the structur…
Escape cascades as a behavioral contagion process with adaptive network dynamics
Wenhan Wu, Xiaoping Zheng, Pawel Romanczuk
Complex behavioral contagion in collective evasion of mobile animal groups can be predicted by reconstructing quantitative interaction networks. Based on the assumption of time-sca…
Individual bias and fluctuations in collective decision making: from algorithms to Hamiltonians
Petro Sarkanych, Mariana Krasnytska, Luis Gómez-Nava +2
In this paper, we reconsider the spin model suggested recently to understand some features of collective decision making among higher organisms [A.T. Hartnett et al., Phys. Rev. Le…
Emergent Metric-like States of Active Particles with Metric-free Polar Alignment
Yinong Zhao, Cristian Huepe, Pawel Romanczuk
We study a model of self-propelled particles interacting with their nearest neighbors through polar alignment. By exploring its phase space as a function of two nondimensional…
Social dilemmas of sociality due to beneficial and costly contagion
Daniel B. Cooney, Dylan H. Morris, Simon A. Levin +2
Levels of sociality in nature vary widely. Some species are solitary; others live in family groups; some form complex multi-family societies. Increased levels of social interaction…
Detecting contagious spreading of urban innovations on the global city network
Niklas H. Kitzmann, Pawel Romanczuk, Jonathan F. Donges
Only a fast and global transformation towards decarbonization and sustainability can keep the Earth in a civilization-friendly state. As hotspots for (green) innovation and experim…
Subcritical escape waves in schooling fish
Winnie Poel, Bryan C. Daniels, Matthew M. G. Sosna +4
Living systems such as neuronal networks and animal groups process information about their environment via the dynamics of interacting units. These can transition between distinct…
Impact of Variable Speed on Collective Movement of Animal Groups
Pascal P. Klamser, Luis Gómez-Nava, Tim Landgraf +3
A variety of agent-based models has been proposed to account for the emergence of coordinated collective behavior of animal groups from simple interaction rules. A common, simplify…
Phases and homogeneous ordered states in alignment-based self-propelled particle models
Yinong Zhao, Thomas Ihle, Zhangang Han +2
We study a set of models of self-propelled particles that achieve collective motion through similar alignment-based dynamics, considering versions with and without repulsive intera…
Collective predator evasion: Putting the criticality hypothesis to the test
Pascal P. Klamser, Pawel Romanczuk
According to the criticality hypothesis, collective biological systems should operate in a special parameter region, close to so-called critical points, where the collective behavi…
Proto-Cooperation: group hunting sailfish improve hunting success by alternating attacks on grouping prey
James E Herbert-Read, Pawel Romanczuk, Stefan Krause +8
We present evidence of a novel form of group hunting. Individual sailfish (Istiophorus platypterus) alternate attacks with other group members on their schooling prey (Sardinella a…
