Mechanosensory interactions drive collective behaviour in Drosophila

Dario Floreano, Lukas Frisch, Pawel Lichocki, Winnie Wing Yee Tse, Pavan P Ramdya

Collective behaviour enhances environmental sensing and decision-making in groups of animals. Experimental and theoretical investigations of schooling fish, flocking birds and human crowds have demonstrated that simple interactions between individuals can ...

Selection methods regulate evolution of cooperation in digital evolution

Dario Floreano, Laurent Keller, Pawel Lichocki

A key, yet often neglected, component of digital evolution and evolutionary models is the 'selection method' which assigns fitness (number of offspring) to individuals based on their performance scores (efficiency in performing tasks). Here, we study with ...

Evolution of division of labor in artificial societies

Pawel Lichocki

Natural and artificial societies often divide the workload between specialized members. For example, an ant worker may preferentially perform one of many tasks such as brood rearing, foraging and nest maintenance. A robot from a rescue team may specialize ...

The Hourglass and the Early Conservation Models-Co-Existing Patterns of Developmental Constraints in Vertebrates

Pawel Lichocki

Developmental constraints have been postulated to limit the space of feasible phenotypes and thus shape animal evolution. These constraints have been suggested to be the strongest during either early or mid-embryogenesis, which corresponds to the early con ...

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 ...

Differences in the Concept of Fitness Between Artificial Evolution and Natural Selection

Dario Floreano, Laurent Keller, Pawel Lichocki

Evolutionary algorithms were proposed to automatically find solutions to computational problems, much like evolution discovers new adaptive traits. Lately, they have been used to address challenging questions about the evolution of modularity, the genetic ...

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 ...

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 ...

The Ethical Landscape of Robotics

Aude Billard, Pawel Lichocki

This paper surveys some of the main ethical issues pertaining to robotics that have been discussed in the literature. We start with the idea of responsibility ascription that arises when an autonomous system malfunctions or harms people. Next, we discuss v ...
