The PSO method, published by Kennedy and Eberhart in 1995, 
is based on a population of points at first stochastically 
deployed on a search field. 
Each member of this particle swarm could be a solution of the optimization 
This swarm flies in the search field (of D dimensions) and each member 
of it is attracted by its personal best solution and by the best solution 
of its neighbours. Each particle has a memory storing all data relating to its 
flight (location, speed and its personal best solution). 
It can also inform its neighbours, i.e. communicate its speed and position. 
This ability is known as socialisation. For each iteration, the objective 
function is evaluated for every member of the swarm. 
Then the leader of the whole swarm can be determined: it is the particle 
with the best personal solution. The process leads at the end to the best 
global solution. 

This direct search method does not require any knowledge 
of the objective function derivatives.

The PSO is a meta-heuristic optimization process created by Kennedy and Eberhart
in 1995.
Three PSO are implanted in this toolbox : 
 * the "Inertia Weight Model" by Shi & Eberhart in 1998, 
 * the "Radius",
 * the "BSG-Starcraft" by the author.

Sébastien Salmon is a mecatronics research engeneer and a PhD. student at the
M3M - UTBM. 
He uses the PSO for actuator optimization and inverse parameter identification.
