Thanks a lot Sir for providing such a helpful video... The speed and method of teaching is very good and the MatLab documentation is absolutely concise and clear...
Wonderful code and a great video. I am unable to figure out how can I use the code for situations where different variables that have different lower bound and upper bounds.

Hi, do you have any academic paper, based on this application? I would like use reference. This is very good, but form of documentation, or academic paper would have even greater value for referencing. Other than that great job and thx for sharing.
Thank you for your video tutorial. Could you please give me information to determine the maximum velocity, why ou decide 0.2 for this equation? how to get it? thank you very much
Thank you Sir. I tried this code and it really worked. But I tried a new function for my research work with this PSO code but it is giving error. I have been trying it for many days but couldn't find the problem. Can I send you mail you the problem
could you please teach these two also : PSOGSA (a combination of Particle Swarm Optimization (PSO) and Gravitational Search Algorithm ) (NS-MFO) for multi-objective problems
I tried to optimise Layeb01 function. It's actual search domain is -100 to 100. If I take search domain -35 to 35 it works well. But if I take search domain -40 to 40 or more than that then error cones
@@YarpizProjects Hello Sir, I appreciate if you can help me with this? I've tried adapt your code to a cost function of 2 variables. The function is z = (1 - x^2) + 100.*(y - x.^2).^2, but when I run PSO, the algorithm does not converge. Does your code works with 2 variables problems? Best regards.
usee the mat lab code to algorithm PSO in path planning and used the the circuit obstacle. Please i help me to change the obstacle from circuit to rectangle
First of all thank you very much sir for those explanations, i would like to ask about how to use this algorithm with simulink, i tried to get data from simulink with this cmd - sim('simulink.slx') to the cost function then type it in the main program but it didn't work efficiently, what to do?
Hello, thank you for this amazing explanation, i have an issue, i followed each step you did but the algorithme doesn't converge quicly, can you explain to me the reason? thank youu
Hi Sir! I would like first to thank you so much for this helpful tuto! i really learned a lot but I am still in want of to get help about my problem: I need to implement or write a code to solve a dynamic optimization problem. How to process to calculate the min of this function: of=A*x(1)+B*x(2)+C*x(3)+D; where x(i) is decision variable and A, B, C and D are functions of t(time) but as constant with respect to variable x(i). For exemple, A(t) may be the output power of a renewable generator source, x(i) the components of the system and of the cost function Please help me! How to organize the code or the different blocs of the main code?

This made me understand PSO from zero knowledge of it, Thanks Sir.
Greatest optimization tutorial ever,, I wish we had lecturers like you...
Thank you very much. Very nice to hear that.
Thanks a lot Sir for providing such a helpful video... The speed and method of teaching is very good and the MatLab documentation is absolutely concise and clear...
This is absolutely amazing. Clear and lucid. I was able to learn and comprehend PSO right from scratch. Thank you so much Sir.
At last i'm successfully run all three code of self type and great feeling. Thank you sir your voice is really very clear.
Thanks Yarpiz for providing such a helpful videos. Language is lucid and matlab documentation is absolutely concise and clear.
finally, I find the tutorial PSO that I understand easy
thank you soo much for this series.. you have done an amazing job in making me understand pso when i had zero knowledge of it.. thankk you
clear demonstration relating topic. learnt a lot. thankx
Thanks Sir for such educative tutorial. My humble question is, if you have a problem with multiple objective functions, what do you do?
Your explanation is great and impressive! Thanks
great explanation. the way you explain and implement every thing is really superb. Stay blessed and thanks alot
sir will be looking forward to videos on Ant colonies optimization
me too!
awesome video tutorial. i've question, if i have my own data and have 5 class to classify, how it will be run?
Wonderful code and a great video.
I am unable to figure out how can I use the code for situations where different variables that have different lower bound and upper bounds.
Just make the following modification to the Algorithm:
pso1 or pso2 file:
problem.VarMin = [.....]; % Vector which element is the lower bound of the specific variable
problem.VarMax = [....]; % Vector which element is the upper bound of the specific variable
PSO function:
% Initialize Population Members
for i=1:nPop
% Generate Random Solution
pos = [];
for j=1:width(VarMin)
pos(i,j) = VarMin(:,j)+randn.*(VarMax(:,j)-VarMin(:,j));
particle(i,j).Position = pos(i,j);
%particle(i).Position = unifrnd(VarMin, VarMax, VarSize);
end
.
.
.
%% Main Loop of PSO
for it=1:MaxIt
for i=1:nPop
.
.
.
% Apply Lower and Upper Bound Limits
for j=1:width(VarMin)
particle(i,j).Position = max(particle(i,j).Position, VarMin(:,j));
particle(i,j).Position = min(particle(i,j).Position, VarMax(:,j));
end
.
.
.
% Apply Velocity Limits
for j=1:width(VarMin)
particle(i).Velocity(j) = max(particle(i).Velocity(j), MinVelocity(:,j));
particle(i).Velocity(j) = min(particle(i).Velocity(j), MaxVelocity(:,j));
end
%particle(i).Velocity = max(particle(i).Velocity, MinVelocity);
%particle(i).Velocity = min(particle(i).Velocity, MaxVelocity);
No words to appreciate.
thank you very much sir. keep going it is very valuable for students who are new to understand optimization problems
Thanks for the great tutorial! Is there a way to implement equality and inequality constraints into this code?
Hi, do you have any academic paper, based on this application? I would like use reference. This is very good, but form of documentation, or academic paper would have even greater value for referencing. Other than that great job and thx for sharing.
GOOD JOB
thank you very much but if we had a Cost function in simulink, what should we do then?
These videos were extremely helpful. Thank you very much for the incredible content and the excellent explanations.

first i like to thanks for your explanation
the second if we have inequality constrains how can we implementation it inside PSO
Very very good! Thank you so much!
So informative
could you please teach these two also :

this is really great video, how we can implement feature selection PSO_SVM , another video will be excellent :)
this is just amazing
sir , can you upload a similar video for MOPSO
Wonderful!
So could you please shed light upon how to coding with a constrained optimization?
Tks, waiting for the ACO

if i have 7 unknown parameters and each one has own lower and uper bound , I try to do PSO to find the 7 unknown parameters for feul cells and each pramters has own bound what can i do
hey, I
have a similar problem ...have you found any solution for the same???
Excuse me sir, I want to ask how to make pid tuning with pso? Please let me know
Thank you sir!!
I watched this video and followed it, but I get an error saying there are TooManyOutputs

What should I do?
run pso instead of pso1
10:10 How does the max/min function compare VarMin (a 1x1 scalar) and particle(i).position (a 1xVarSize array)? What dimension is the resut?
Okay found the answer to my query. max/min function returns a 1xVarSize array.
eg.
A = [1 2 3 4 5]
B = 3.5
C = max(A,B)
output: C = [3.5 3.5 3.5 4.0 5.0]
D = min(A,B)
output D = [1.0 2.0 3.0 3.5 3.5]
thank you sir
