How to plot the population/particle in Particle Swarm Optimization iteratively?

I did some programming about PSO. I want to show the movement of my particles/swarms every iteration. It will show like animation because every particle will move based on the result of every iteration. Anyone can help me with the coding or has any idea about this?

hello, did u plot it if yes can you help me

I see your questions are dated. So I'll answer for other people.

You need to store all the values (the X-positions) of your particles at each iteration, and then you just make a loop to display each iteration.

For example if you have this form Swarm(n).Particles(i).X to designate the X position of the i-th particle at the n-th iteration, you can use this code:

for n= 1: max_Iteration

clf;

for j=1:noP

plot(Swarm(n).Particles(j).X(1),Swarm(n).Particles(j).X(2),'k.', 'MarkerSize', 30)

hold on

grid on

end

pause(1); %Pause a little bit before plotting the next iteration

end

Where noP: is number of particles

And here you go!

Thank you ! That's helpful

Hi! How did u save all the values (the X-positions) of your particles at each iteration?
