Particle Swarm Optimization Toolbox

With Trelea, Common, and Clerc types along with ...

Description

Robust Particle Swarm toolbox implementing Trelea, Common, and Clerc types along with an alpha version of change detection.

This toolbox is designed for researchers in Computational Intelligence as well as application developers, students, and classroom labs. It is robust enough that several papers have been developed using it but it is also in constant development and very easy to hack. Users of MATLAB's Optimization Toolbox should feel right at home but even if you don't use that toolbox this will be easy to figure. Extensive help is included.

Anyone from serious AI researchers to beginning students should get something out of this.

This toolbox is constantly evolving and I welcome suggestions.

Current feature set:
* Trelea, Clerc, and Common Types
* Vectorized and non-vectorized versions, you can investigate thousands of particles at once with the proper cost function.
* custom plotting plug ins
* neural net trainer (requires Matlab's neural net toolbox)
* PDF Particle Swarm Introduction
* Alpha version of change detection, will track dynamic environments
* includes suite of test functions commonly used in the CI/optimization community.

• Acknowledgements: This submission has inspired the following:; PSO solution to economic dispatch, Improved PSO program to solve Economic Dispatch, Another Particle Swarm Toolbox, Neural Network add-in for PSORT
• Required Products: Neural Network Toolbox
• MATLAB release: MATLAB 7.0.1 (R14SP1)
• Other requirements: * current version works in Matlab 7 but has been in development since Matlab 5 so might work in the earlier versions too.

I don't know much about theis, but if the program won't run on the example included in the help, then I think I can't use it:

> out = pso_Trelea('f6',2)
??? Error using ==> f6
Too many input arguments.

Error in ==> pso_Trelea at 203
    out(j)=eval(evstrg); % evaluate desired function with particle j

Brian, could you please give a more examples. I find it excellent for a new learner like me about the subject.

[John D'Errico]

A nice, sophisticated PSO toolbox. The only flaw is it feels like the interface & documentation needs some attention - apparent defaults that did not seem to default as the documentation implies. A simple test crashed for no apparent reason. I noted that the documentation did not even tell you the correct name of the function used to drive the optimizer. Once you get past these minor points and learn how to drive it properly, I think this is a nice toolbox. I'd like to give it about a 3.75 rating.

I am wondering if this PSO can deal with discrete parameter optimization problems. Thanks a lot!

[John D'Errico]

I like the cleanup that was done, so I thought it was time to revisit this (nice, sophisticated) tool. Great graphics, at least where this is possible. If I want to complain about anything, its the fact that PSOt REQUIRES its function in the form of an m-file. Neither inline or anonymous functions are supported. Its a silly constraint, because my guess is the only reason is to include the function name on the generated graphics. Otherwise feval should be insensitive to these alternatives. The advantages that anonymous functions (especially) offer suggests fixing this. On the other hand, this is a really nice piece of work, so I'll raise my rating to a 5 anyway.

Thanks,I downloaded it. It is helpful for me to learn PSO.

this doesn't work with version 5.1 of neural network

[Tricia Rambharose]

I am a research student at the University of the West Indies.

A collegue of mine used trainpso and newff to train a neural network. He used Matlab version 5 and it worked well. I am using Matlab version 7.6.0 and neither trainpso nor newff works.

With this toolbox 'DemoPSOBehavior' and pso_Trelea_vectorized('f6',2) works with my Matlab version, but 'demoPSOnet' does not work. I get this root error :

??? Error using ==> trainpso at 124
Unrecognized code.

Is there any other way to train a Neural Network by PSO using this toolbox?

[jjjjjjjjjjjjjjjj jjjjjjjjjjjjjjjjjj]

Hi friend,
I am a PhD Research Scholar in Indian Institute of Technology, Roorkee, India.
After working for 4 hours continuously, i am able to run train the Neural network program using this PSO toolbox.
I am vary thankful to you. Great job.
I can help, if anybody is in need of my help.

[Ali Sabbagh]

Dear jalla
would you please help me how it work?
i spend too much time to understand but i was not successfull
thank you

[Shree Guha]

I found this helpful. I had to modify the function to fit my problem description. I have a lot more to work on it. But i like it so far! Thanks again.

[Homri]

Hello,
Please who can help me for the choice of parameters trainpso
thank you

[vishal mehra]

hello
can anyone help me?
when i run the command at command window for testing the fn f6 i got the error as below.

out = pso_Trelea_vectorized('f6',2)
??? Undefined function or method 'normmat' for input arguments of type 'double'.

Error in ==> pso_Trelea_vectorized at 252
  pos(1:ps,1:D) = normmat(rand([ps,D]),VR',1);

can anyone tell me now what i have to do?

[saeed gol Golian]

hi everyone
I encountered with the same error as vishal mehra

?? Undefined function or method 'normmat' for input arguments of type 'double'.

Error in ==> pso_Trelea_vectorized at 252
  pos(1:ps,1:D) = normmat(rand([ps,D]),VR',1);

can anyone give me a hand?

[Eric]

Saeed and Vishal,
You need to manually add the subdirectories to your path, e.g. /hiddenutils and /testfunctions for the demo.

Anyway, I'm still learning how to use the PSO tool - so far so good! I'll come back with a rating once I've explored it further.

[tom]

Hi, everyone,
   I am interested in PSO with both linear and nonlinear constraints for high-dimention problem, but I found this package can not handle it.
   Is there any other PSO toolbox to handle the problems with nonlinear and linear constraints? Please let me know: [e-mail]. I am waiting for your reply.

   Thanks,
Tommy

[Mohammed Ahmed Saeed]

i prepare for my Master in optimal relay coordination and if you please i need your help to provide me with a swarm code to determine the optimal relay settings ( i can not do the fitness function for each particle )
Thanks

[Zacharias Voulgaris]

I am also interested in discrete PSO for TSP. If anyone has something in Matlab, please contact me. Thanks.

[Tusi Bai]

How to use it to multi-objective optimization problems?

[e-mail]

[Brian Birge]

Hey everyone, sorry for taking so long to update this, it will be updated shortly and contain discrete capability as well as multi-objective optimization built in and more flexible constraints (linear or nonlinear). If you wish to do multi-objective opt "lite" right now you can, just write your cost function so it has a weighted sum of your objectives as the output, a standard way to do it. More complex methods will be added with the update.

[syed musthafa]

dear all,
i need pso coding for OPIMAL LOCATION OF FACTS DEVICES..i also need ur valuable suggestions to do this project..kindly send me the codings/suggestions...

[Shawkat hamdan]

hi Brian
i want to ask you if you have program in which we can make tuning the parameters of the pso like w, c1, c2 to make the pso more effective as results

I am currently working on a research project.
I am trying to train a neural network using PSO.
 When using the PSO toolbox with Matlab version
7.6.

demoPSOnet' does not work. I get the following error :
??? Error using ==> trainpso at 124
Unrecognized code.
If I can find a simple way to train the Neural Network using the PSO toolbox it will be of great help to me.

Please can anyone assist me in anyway.

Good day everyone,

For those of you who emailed me asking for assistance in using PSO for NN training, and also for the general public, I found another PSO toolbox to be very helpful to me. The toolbox I now use is found at

http://www.mathworks.com/matlabcentral/fileexchange/28291-particle-swarm-optimization-research-toolbox

I have added functionality for this PSO toolbox to be used as a training algorithm for a NN. This version is currently being tested and will then be made available.

[junjie]

Thank you very much, with these, I can use pso more quickly.

[Tricia Rambharose]

Good day users,

A PSO toolbox which can be used for NN trainig, and works with the latests versions of MATLAB, is now available on MathWorks.

The PSO toolbox is found at:
http://www.mathworks.com/matlabcentral/fileexchange/28291-particle-swarm-optimization-research-toolbox

The NN add-in for this PSO toolbox is found at: http://www.mathworks.com/matlabcentral/fileexchange/29565-neural-network-add-in-for-psort
