Seminar #72: Slime-moulds and Swarming

Posted in Seminars by matthewegbert on October 22, 2010

These talks were given this Wednesday, Oct 20th.  Apologies for not listing these talks here ahead of the actual talks.  For completeness, I’m now including their description on this site.

Nick Hockings has recorded video of these two talks that were given on Wednesday. Click here to get to the videos.

Mould Intelligence: Computation with Slime Mould
Soichiro Tsuda — University of the West of England Bristol
Oct 20. 3pm — 4pm – Arundel 401

A plasmodium of true slime mould Physarum Polycephalum shows various
kinds of interesting behaviour, such as multiple cell fusion,
autonomous contraction oscillation, and optimised network formation,
even though it is just a single-cell organism. The talk will give a
brief overview of research on the “primitive intelligence” of this
natural swarm intelligence system and how this organism can be used
for information processing.

Soldier Crab Swarming and Dual Neighborhood System model
Yukio-Pegio Gunji (Kobe University)

Oct 20. 4pm — 5pm – Arundel 401

Soldier crabs in Japan make a big swarming composed of from hundreds
to several thousands individuals.  >From the observation of soldier
crab behavior we constructed a model for swarming, featuring two kinds
of neighborhood. Our model can mimic the wondering behavior of swarms,
mass effect to crossing the water, and oscillating behavior in a
closed container (crab clock). It also explains the scale-free
correlation, which recently found in a bird flock. Because our model
contains inherent noise that can actively contribute to form a
coherent swarm, it can make it possible that coherent swarm mass
coexists with critical behavior associated with the power low.
Compared with boids, we show that swarms in our model are robust
against external perturbation.
