Neural networks as mechanisms to regulate division of labor

Dario Floreano, Laurent Keller, Pawel Lichocki

In social insects, workers perform a multitude of tasks such as foraging, nest construction and brood rearing without central control of how work is allocated among individuals. It has been suggested that workers choose a task by responding to stimuli gath ...

Genetic Team Composition and Level of Selection in the Evolution of Cooperation

Dario Floreano, Laurent Keller, Markus Waibel

In cooperative multiagent systems, agents interact to solve tasks. Global dynamics of multiagent teams result from local agent interactions, and are complex and difficult to predict. Evolutionary computation has proven a promising approach to the design of ...

Evolving team compositions by agent swapping

Dario Floreano, Laurent Keller, Pawel Lichocki

Optimizing collective behavior in multiagent systems requires algorithms to find not only appropriate individual behaviors but also a suitable composition of agents within a team. Over the last two decades, evolutionary methods have been shown to be a prom ...

Targeted worker removal reveals a lack of flexibility in brood transport specialisation with no compensatory gain in efficiency

Mahmut Selman Sakar, Laurent Keller, Fazil Emre Uslu

Division of labour is widely thought to increase the task efficiency of eusocial insects. Workers can switch their task to compensate for sudden changes in demand, providing flexible task allocation. In combination with automated tracking technology, we de ...

Influence of the level of polyandry and genetic architecture on division of labour

Dario Floreano, Laurent Keller

Genetic diversity is thought to be a main factor in determin ing task performance and behavioral plasticity of social insect colonies. This diversity has two main causes. a) Multiple matings by the colony queen (polyandry) and b) the number of regions on t ...

Limitations of response thresholds models of division of labor

Dario Floreano, Laurent Keller, Pawel Lichocki

High levels of cooperation are often cited as the primary reasons for the ecological success of social insects. In social insects, workers perform a multitude of tasks such as foraging, nest construction and brood rearing without central control of how wor ...

Precise tactile stimulation of worker ants by a robotic manipulator reveals that individual responses are density‐ and context‐dependent
