Dear Dr Abbas

Attachment you can find a general code for PSO method, hope to be of help.

Cheers

Think this might help you.

You can check this link, for a MATLAB implementation of Particle Swarm Optimization (PSO):

Hello there, 

You can use of this source code in Matlab for Accelerated Particle Swarm Optimization. I think is useful for you.

Description

This is an accelerated PSO (APSO). APSO does not use velocities or any inertia parameter.

A full program for solving nonlinear constrained optimization problem (welded beam design as an example) is provided, which can be extended to solve other continuous optimization problems.

MATLAB release

MATLAB 7 (R14)

PSO codes in MATLAB is available here;

Code Codes in MATLAB for Particle Swarm Optimization

Kindly, go through the following publication.

I hope it will be very helpful to you.

 Hi,Mahammad  Nabab Alam, Can that code can be used for multi-objective PSO algorithm? Based on my understanding it is only for single objective.

This is simple PSO matlab code, you can refer it .....

https://dg-algorithm.blogspot.com/2016/04/

Hope this simple code for PSO may help !

function [p_min, f_min, iter]=pso(func, numInd, range, n_var, tolerance, numIter, pesoStoc)

% It finds the absolute minimum of a n variables function with the Particle

% Swarm Optimization Algorithm.

% The input parameters are:

% -func: it's the objective function's handle to minimize

% -numInd: it's the number of the swarm's elements

% -range: it's the range in which the elements must be created

% -n_var: it's the number of function's variables

% -tolerance: it's the tolerance for the stop criterion on the swarm's

% radius

% -numIter: it's the max iterations' number

% -pesoStoc: it's the swarm's movability

%

% The output parameters are:

% -p_min: the minimum point find

% -f_min: the minimum value of the function

% -iter: the number of iterations processed

func='obj.m'; % your objective function to be minimized/maximized

numInd=30;

range=[0 1];

n_var=8;

tolerance=1;

numIter=100;

pesoStoc=1;

end

[valF_ord,index]=sort(valF); % Sort the objective function's values for the swarm and identify the leader

leader=ind(index(1),:);

for l=1:size(ind,1) % Calculates the new velocity and positions for all swarm's elements

fi=rand();

v(l,:)=(1-(sqrt(k*fi))/2)*v(l,:)+k*fi*(leader-ind(l,:)); % Velocity

ind(l,:)=ind(l,:)+(1-(sqrt(k*fi))/2)*v(l,:)+(1-k*fi)*(leader-ind(l,:)); % Position

end

Many thanks,I will try th code

I need the source code  of PSO which can display the position of the particles ie the coordinates x y and z of each particle in each itteration please Many thanks

I have attached a file. Hope to be useful

Dr.Erfan Veisi

can you send me the file of Function 'CostFuncName' I tried to compile it but I had an error because it calls this function and it does not excite in the file that you sent it to me.

THank's

OK

Dr.Erfan Veisi

I need the file function CostFunction-Fcn, I tried to compile your code but I had an error because it calls this function and it does not excite in the file that you sent it to me

Thank's

https://www.youtube.com/watch?v=AE0jDQ1I2mY&t=5s

with explanation

thank you Muhammad Raza is very useful

Dr.Erfan Veisi

I thank you for your help but what I am looking for in my code is the display of Cartesian coordinates of each particle (x, y, z) in each itteration I do not know how to do it if you have a sugesstion tell me please

• this code

Hi Ameer L.Saleh

thanks for your answer sir but your code does not work

I recomend you to implement. In its easy form. it can be programed in few code lines

ameerwnn ??

You can try Method of Moving Asymptotes (MMA) developed by K. Svanberg.

It is a general and common optimisation algorithm for constrained and unconstrained problem with any number of constraint functions.
