Two articles at the ANTS 2018 conference

We just published two papers in the Proceedings of the 11th International Conference on Swarm Intelligence (ANTS 2018) which will be held in Rome on October 29th-31st, 2018.

The paper Quality-sensitive foraging by a robot swarm through virtual pheromone trails by Anna Font Llenas, M. Salah Talamali, Xu Xu, James Marshall, and Andreagiovanni Reina showcases the functioning of ARK, our new super-cool infrastructure of Augmented Reality for Kilobots.

The paper Simulating Kilobots within ARGoS: models and experimental validation by Carlo Pinciroli, M. Salah Talamali, Andreagiovanni Reina, James Marshall, and Vito Trianni proposes a new plugin for the ARGoS simulator that allows users to simulate Kilobots in a fast and realistic way, to use the same code in simulation and on robots, and to simulate the ARK infrastructure along with the Kilobots.

Psychophysical Laws and the Superorganism

Looking at honeybees in a colony as if they were neurons in a brain could help understand the basic mechanisms of human behaviour. A bee colony can be considered as a single superorganism, composed of tens of thousands of bees, which displays a coordinated response to external stimuli. Our recent paper, published in Scientific Reports and authored by Andreagiovanni Reina, Thomas Bose, Vito Trianni, and James Marshall, has shown that honeybee colonies might respond to stimuli in the same way other organisms, such as humans, do. The superorganism response is the result of interactions between individual bees; finding which type of interactions generate brain-like responses helps researchers to identify the general mechanisms generating these responses, and may ultimately lead to a better understanding of our brain.

TREE Opinion on confidence and collective decision-making

A new Opinion on individual confidence and collective decision-making is in press in Trends in Ecology and Evolution, authored by James together with Andy Radford (Bristol) and Gavin Brown (Manchester).

The Opinion argues for the consideration of subjective confidence and its influence on communication within collectively-deciding groups. The Opinion also draws links between confidence by individually-optimal decision-makers, and the optimal confidence-based weighting scheme for group decisions.

Collective Behaviour Minisymposium

Thomas, James and Giovanni co-organised a minisymposium on Collective Behaviour and Decision Making, at the 2017 Mathematical Models in Ecology and Evolution conference in London.

The speakers covered a diverse range of topics, from naming games to building the Matrix for fish. The full list of speakers and titles is as follows:

  • Andrea Baronchelli (City University London) – The spontaneous emergence of conventions
  • Andreagiovanni Reina (University of Sheffield) – A model of the best-of-N nest-site selection process in honeybees
  • Arianna Bottinelli (Nordic Institute for Theoretical Physics) – The breakdown of coordination and the emergence of dangerous collective motions in high-density crowds
  • Colin Torney (University of Glasgow) – Cues and collective decision-making in migrating ungulates
  • Renaud Bastien (University of Konstanz) – A simple model of collective behaviour driven by the visual field
