•The emergent collective intelligence of
groups of simple agents.
•Swarm intelligence seems not to be an
accident but rather a property of a
variety of systems
 identification of analogies: in swarm biology and IT
system.
 understanding: computer modelling of realistic
swarm biology
 engineering: model simplification and tuning for IT
applications
 ants solve complex tasks by simple
local means
 ant productivity is better than the
sum of their single activities
 ants are ‘grand masters’ in search and
exploitation
2 ants start with equal probability of going on either
path.
The ant on shorter path has a shorter to-and-
fro time from it’s nest to the food.
The density of pheromone on the shorter path is
higher because of 2 passes by the ant (as
compared to 1 by the other).
The next ant takes the shorter route.
Over many iterations, more ants begin using the path
with higher pheromone, thereby further reinforcing it.
After some time, the shorter path is almost exclusively used.
‘Self-organization is a set of
dynamical mechanisms
whereby structures appear at the
global level of a
system from interactions of its
lower-level components
Robotics / Artificial Intelligence
 Process optimization / Staff
scheduling
 Telecommunication companies
 Entertainment
 biology makes compromises between
different goals
 biology sometimes fails
 some natural mechanisms are not well
understood
 well-defined problems can be solved by
better means
self-organization is based on:
 activity amplification by positive
feedback
 activity balancing by negative feedback
 amplification of random fluctuations
 multiple interactions
stigmergy - stimulation by work - is
based on:
 work as behavioural response to the
environmental state
 an environment that serves as a work
state memory
 work that does not depend on specific
agents
 Provide heuristic to solve difficult
problems
 Has been applied to wide variety of
applications
 Can be used in dynamic applications
