Summary
This optimization module is an implementation of the particle swarm optimization algorithm for single- and multi-objective optimization (1), however it contains some modifications to the publication. The algorithm reflects the natural movement of flocking birds.
The algorithm is elitist: Always the best particles are kept as guides.
This algorithm is designed for continuous variables and can not handle discrete problems. Furthermore, the algorithm is implemented for minimizing a single and multiple objective function(s).
Properties
General
| Algorithm | stochastic - stochastic adaptation of the velocities. |
|---|---|
| Design Variables | Written for continuous variables. No discrete or mixed variables are possible. |
| Objectives | single- and multi-objective for minimization. |
| Constraint handling | no |
| Boundary handling | no |
| Initialization | Requires at least one of the following: initial search region or bounds. |
Connections
| Starting at this module | Module requires exactly one connection of type optimization.

Module Description
Initialization
The initial particles are randomly generated within the initial search region (if existing) or otherwise between the bounds.
Optimization
The algorithm contains stochastic processes and operates with a set of particles. Parallelization on the basis of the number of particles is implemented.
