An individual-based model of collective attention (2009)

Moussaid, Mehdi, Helbing, Dirk, Garnier, Simon, Johansson, Anders, Combe, Maud, Theraulaz, Guy
In animal societies as well as in human crowds, many observed collective behaviours result from self-organized processes based on local interactions among individuals. However, models of crowd...

Eric Bonabeau, Guy Theraulaz, Bertrand Schatz, Jean-louis Deneubourg
this paper is simple, plausible, remarkably consistent with experiments, and relies solely on empirically measured parameter values. On the negative side, additional measurements are needed to...
Latency Time and Absence of Group Effect: Two Examples (2007)
Jean-louis Deneubourg, Eric Bonabeau, Guy Theraulaz
We suggest that group effect need not be invoked to explain the differences in latency times exhibited by groups of different sizes in the initiation of building in the termite Macrotermes...
Eric Bonabeau, Andrej Sobkowski, Guy Theraulaz
Abstract. Social insects provide us with a powerful metaphor to create decentralized systems of simple interacting, and often mobile, agents. The emergent collective intelligence of social insects--...
Emergent Behavior in Agent Networks: Self-Organization in Wasp and Open Source Communities (2006)
Valverde, Sergi, Theraulaz, Guy, Gautrais, Jacques, Fourcassie, Vincent, Sole, Ricard V.
Understanding the complex dynamics of communities of software developers requires a view of such organizations as a network of interacting agents involving both goals and constraints. Beyond their...
Self-organization patterns in wasp and open source communities (2006)
Sergi Valverde, Guy Theraulaz, Jacques Gautrais, Vincent Fourcassié
analysis shows that wasp colonies and open source software communities share statistical organization patterns. Studying these patterns reveals self-organizing processes that form social hierarchies.

Response Threshold Reinforcement and Division of Labour in Insect Societies (1998)
Guy Theraulaz, Eric Bonabeau, Jean-Louis Deneubourg
this article, but the reinforcement mechanism that was described can certainly lead to stable patterns of temporal polyethism. More generally, the formulation of the model lends itself to many...
The Phase-Ordering Kinetics of Cemetery Organization in Ants (1998)
Eric Bonabeau, Guy Theraulaz, Vincent Fourcassié, Jean-Louis Deneubourg
The clustering of dead bodies by ants is simulated, using a cellular automaton model, the rules of which are carefully derived from experiments. Starting from a random spatial distribution of...
Spatial patterns in ant colonies
Theraulaz, Guy, Bonabeau, Eric, Nicolis, Stamatios C., Solé, Ricard V., Fourcassié, Vincent, Blanco, Stéphane, ...
The origins of large-scale spatial patterns in biology have been an important source of theoretical speculation since the pioneering work by Turing (1952) on the chemical basis of morphogenesis....

Response Threshold Model of Division of Labour in a Ponerine Ant
Eric Bonabeau, Guy Theraulaz, Bertrand Schatz, Jean-Louis Deneubourg
A simple response threshold model is used to explain a pattern of division of labour observed in the ponerine ant Ectatomma ruidum, where it was found that prey-foraging behaviour could be subdivided...
Within-Brood Competition and the Optimal Partitioning of Parental Investment
Eric Bonabeau, Jean-Louis Deneubourg, Guy Theraulaz
