pso-function

A generic particle swarm optimization function for Matlab

Here you can find the latest version of our particle swarm optimization function for Matlab. Detailed documentation of the PSO function is found in the following publication

PSO function for Matlab version 0.6.0

pso.zip (ZIP, 33 KB) (right-click and save as)

This download includes the PSO function pso.m, two examples, and additional helper functions such as the plotting function psoplotbestf.m. The first example is the Ackley problem which is a common academic test problem. The second example, is a simplified problem of optimizing the gear ratios in a hybrid electric drivetrain.

Contact information

Contact if you have any questions related to the pso-function.

Note: The PSO function requires the Matlab Optimization Toolbox. Furthermore, the current version has been tested on Matlab R2012b. You may (or may not) experience problems if you are using an older version of Matlab. In case of problems, please contact us so we can identify the problem and take appropriate action. Your feedback is appreciated!

Citation

Please be so kind to cite our PSO function [1] if you use it in your published research.

Subroutine Generator

Subroutine generator for one-dimensional catalytic reactors

SubGen is a code-generator based software which automatically generates FORTRAN subroutines describing a tubular catalytic reactor from simply structured xml-input files
The input files specify the reacting species together with their thermodynamic properties and the complete reaction network.

The generated FORTRAN subroutines can then be linked to the adaptive PDE solver BACOL which shows a high computational performance and has been extended with a MATLAB interface for convienient usage.

Details of the software are presented in

T. R. Boehme, C. H. Onder, L. Guzzella, "Code-generator based software package for defining and solving one-dimensional, dynamic, catalytic reactor models", Computers & Chemical Engineering, submitted for publication

If your are interested in using the code, please contact me by e-mail.
