The PSO TOOLBOX is a collection of Matlab (.m) files
that can be used to implement the Particle Swarm Optimization
Algorithm (PSO) to optimize your system.
PSO algorithm was introduced by Russel Ebenhart (an Electrical
Engineer) and James Kennedy(a Social Psychologist) in 1995
(both associated with IUPUI at that time). It belongs to the
categories of Swarm Intelligence techniques and Evolutionary
Algorithms for optimization. It was inspired by the social
behavior of birds, which was studied by Craig Reynolds (a
biologist) in late 80s and early 90s. He derived a formula
for representation of the flocking behavior of birds. This
was later used in computer simulations of virtual birds, known
as Boids. Ebenhart and Kennedy recognized the suitability
of this technique for optimization and came up with the Particle
Swarm Optimizer.
The representation of the optimization problem is similar
to the encoding methods used in GAs. Instead genes, the variables
are called dimensions, that create a multi-dimensional hyperspace.
"Particles" fly in this hyperspace and try to find
the global minima/maxima, their movement being governed by
a simple mathematical equation.
