Ants in your kitchen are chaotic? Find many other interesting questions in this free book!
Social
behaviour in ants of the genus Leptothorax
is reviewed. Attention is paid to the
existence of collective robust periodic
oscillations
in the activity of ants inside the nest. It is known that those
oscillations are the outcome of the
process of
short-distance interactions among ants and that the activity of
individual workers is not periodic. Isolated
workers can activate spontaneously in an unpredictable fashion. A
model of an artificial
society of
computer automata endowed with the
basic behavioural
traits of Leptothorax
ants is
presented and it is demonstrated that collective periodic
oscillations in the activity domain
can exist as a consequence of
interactions among
the automata. It is concluded that those
oscillations are
generic properties common to both natural and artificial
social
complex systems. Are chaotic ativity of ants similar to the disordered activity of humans?
