You are a legend , you are a diamond , you are a hero even I stay here for the whole of my life I can't describe how a wonderfull teacher realy you are , thank you so much .
I believe this video is very helpful, expecially for those people approaching ACO for the first time. Having said that, I have a question about ACO. The heuristic information in your example is based on the cost of the single arc. But in many application the cost of a single component is influenced by the value assumed by the other componets. For istance, consider a problem of pump scheduling in water distribution networks, the actuation of a pump in a precise time interval produce a cost that depends on the pump state (on/off) during the preceding time intervals, and it influences the costs of the subsequent time intervals. In this case, how the pheromone trails can be updated? Because the cost function depends on the whole path the ant follows and not by a single component of the path.
I really enjoyed this clearest way to explain things and making super simple and understandable. Thank you so much. this my first sight of your course and i will stay learning here
Reminds me on Markov chains. Hard part is that every time concentration of feromon is different so probability changes. If also quality of road change I wonder how to calculate stationary distribution if there is any at all.
Thank you, Ali.. your video is very helpful to finish my task. I didn't know before, this algorithm can be understood in an easy way. Hope to see more of your video. Thank you
guys please when we are talking about I,j, Is the current ant position and j is one of the next steps around it like the left to right ? or j is the final destination like nest or car and tree?
If my problem is a combinatorial problem, but I can only calculate the cost once a full trail has been formed, how can I calculate the distance between two nodes? Or should I just ignore that part?
at 6:44 in the video, you say if roh is equal to 1 the evaporation is at its maximum, but mathematically if roh is equal to 1 the first term of second equation will become zero and we will be left with the equation which is equal to pheromone level without evaporation. so what's going on here?
Sir, thank you for the effective video, and for your effort, can you please explain to us the Artificial Bee Colony optimization, sir can I use the ABC algorithm to solve the shortest path problem? another question please, what are the meta-heuristics methods used to solve the shortest path problem? waiting for your response thank you in advance.
Ali, I've watched many RUclips videos and yours is without a doubt the best explanation. I'm working on a small project using your algorithm to develope an app for iOS. At 9:21, what if there is a path that hasn't been taken yet? That path would have a Pheromone value of 0? Even with the evaporation model the value would be 0. How do you consider this path to be taken? Thank you.
I assume they would normally originate from a nest, but in reality there will of course be situations where scouts take random routes that eventually become solid paths. That's why most ant lines aren't the perfect shortest path from source to nest, but are shorter relative to routes taken by other scouts.

The clearest video on youtube about Ant Colony Optimization, thank you very much Dr. Ali. Just a little correction on [5:05](ruclips.net/video/783ZtAF4j5g/видео.html), the formula for the total pheromone from edge i-j, (T^{i, j}) shouldn't have the K superscript.
Shouldn't the kth tau equal the old tau plus the change in tau, if there is no vaporization? The way it is written now (6:10) means rho = 1, which equals maximum vaporization. Or am I misunderstanding something?
amazing video!!! very well explained!! Only suggestion, not trying to be rude, but some words at moments can be a tiny bit hard to understand, my suggestion is maybe type of the captions? Other than that great video!
you have upload your code inmatlab . i ma facing difficulty in running that code in matlab. can you help me in that . i tink i am facing a problem i calling function into other function in matlab. can you give some advise
This lecture remained very use full. Thank you so much sir. Kindly upload a video, regarding how to program this algorithm (ACO) in any of the programming language like python, IBM LOG cplexx or matlab. Thanks
I have a question concerning evaporation rate - Why is time not a variable in the equation for pheromone levels? Additionally, how can one include more environmental variables such as temperature, terrain, humidity, light, etc. or colony variables such as speed of ants, density, distribution, type of ant, etc. into the algorithm? Is there any other type of communication that occurs between individuals?
The assumption that ants know the cost/distance is invalid. we need to make the model naturally realistic not based on human intelligence but based on ants intelligence. phermones should be the only parameters used in the model.
Wanna know whether the pheromone is updated locally on each arc visited by ant or the pheromone is updated globally after the ants visits all the arcs in a complete path....?
shouldn't the evaporation be subtracted rather than added to current pheromone level? at 10:44 the pheromone level has increased from 0.1 to 0.6 with evaporation.
Incredibly well explained. Especially with the visual and mathematical examples. Thank you very much Mister Mirjalili! I took the opportunity to subscribe to some of your udemy course. I hope, later this year, I will have enough time to learn more about this and the other algorithms.

Excellent visualization and presentation. Kudos
You have great teaching and presentation skill. Thank you for making this video.

Wonderful explanation. All doubts have been cleared.
If my problem is a combinatorial problem, but I can only calculate the cost once a full trail has been formed, how can I calculate the distance between two nodes? Or should I just ignore that part?
How we can apply ant colony with clustering?
Sir I want implementation of exam time table problem using ant colony
Please upload videos on particle swarm optimisation
why do we need to connect every node with every other node???
Great explanation, thank you very much!
at 6:44 in the video, you say if roh is equal to 1 the evaporation is at its maximum, but mathematically if roh is equal to 1 the first term of second equation will become zero and we will be left with the equation which is equal to pheromone level without evaporation. so what's going on here?
Thank you very much Dear Dr.Ali for this video
please sir how to determine the matrix of pheromone
Nicely explained.....
The link in description is not working......
Thanks a lot. Ooops; I have updated the link.
Sir, thank you for the effective video, and for your effort, can you please explain to us the Artificial Bee Colony optimization, sir can I use the ABC algorithm to solve the shortest path problem? another question please, what are the meta-heuristics methods used to solve the shortest path problem? waiting for your response thank you in advance.
very informative lecturer may be in future i will take some help regarding ACO
How can i get these slides??
How do you guarantee that the pheromone on the edge will not become 0?
Superb..fida hogaya..want to register for the course..getting problem in sign up..can u provide lecture on firefly algorithm please
Thank you very much. It is clear. I understand it very well
This helped me a lot. Thank you very much
many thanx , amazing presentation.

Thank you.
I suppose that all the pheromones at the beginning will be set to 1
Sir any good multi objective course on udemy?
Do the ants have to be initialized from the same starting point? Or different?
Cause I'm seeing both online
I assume they would normally originate from a nest, but in reality there will of course be situations where scouts take random routes that eventually become solid paths. That's why most ant lines aren't the perfect shortest path from source to nest, but are shorter relative to routes taken by other scouts.
what does the alpha and beta defins in that particular equation? please help me .
Those are some parameters to change the impact of pheromone and the quality of an edge on calculating the probability.

great work
specially the slides are too good to understand , thank you brother
Sir, please explain Antlion Optimization. I already emailed you about it. Please explain it with its mathematical function.
The clearest video on youtube about Ant Colony Optimization, thank you very much Dr. Ali. Just a little correction on [5:05](ruclips.net/video/783ZtAF4j5g/видео.html), the formula for the total pheromone from edge i-j, (T^{i, j}) shouldn't have the K superscript.
Very, very good explanation and numerical examples helped me a lot to understand it even more. Amazing job!
Hi Prof. Ali
Thanks for your explaining ACO.
How can I find your email?
Shouldn't the kth tau equal the old tau plus the change in tau, if there is no vaporization? The way it is written now (6:10) means rho = 1, which equals maximum vaporization. Or am I misunderstanding something?
You are right, this should be written as : tau = ( 1 - rho ) .* tau;
Thanks a million for this video. You saved my grades
wowwwwww mannnnnnnn, just god level teaching .god bless u bro
amazing video!!! very well explained!!
Only suggestion, not trying to be rude, but some words at moments can be a tiny bit hard to understand, my suggestion is maybe type of the captions? Other than that great video!
you have upload your code inmatlab . i ma facing difficulty in running that code in matlab. can you help me in that . i tink i am facing a problem i calling function into other function in matlab. can you give some advise
Thanks you so much sir for this wonderful explanation...this help me alot🙏🙏
Is thia guy the same Mirjalili who gave the fireflies,moth and crow optimization algorithm 😲😲...u are so awsm
This lecture remained very use full. Thank you so much sir.
Kindly upload a video, regarding how to program this algorithm (ACO) in any of the programming language like python, IBM LOG cplexx or matlab. Thanks
Thanks a lot. As far as I know, ACO has been implemented in a large number of programming languages.
thanks , that was quite helpfull .
The content is really helpful and even the formatting of the video is very sorted. Thanks
The last equation at 6:41 is wrong
Yep, it is supposed to be tau = ( 1 - rho ) .* tau;
Thank you for the effective video 🤩.
You made me clear so that I can handle my mini project!!!
Hi Nitheesha shree i am working on route optimization. can you please share your project.
Great and subtle explanation. The numerical examples and graphics are incredibly helpful. Thank you so much!
Moi je pense que 1+1 est égal à deux et puis c'est tout.
Thank you for the detailed explanation and the wonderful accuracy in explaining this algorithm. I hope you explain the gorilla algorithm as well.
Hi Professor, I was trying to look for this original math model in an official published resource... What is your resource please can you share it?
Man, you are THE BEST !
Wow, that made it so much clearer, thank you!!
At first I was having hard time understanding but then everything made so much sense ... that was some awesome explanation ... !!! good work man !
You explained the complex ACO problem in such simple understandable way! Great job!

Sir any multi objective optimization intergrated with artificial intelligence course on udemy?
I want to make project on Grasshopper Optimization algorithm please give me some ideas...
How do we find and solve alpha and beta in that equation ? Please help me
It's up to you. You can choose any. Just try different values and leave values that work the most effective.
amazing video
Great video sir, can i use this model for optimization in scheduling of activities in a construction industry????
What is the time complexity of any optimization based evolutionary algorithm?
thank you for your crystal and clear description of ACO. I hope you become hero of your life
Thank you so much Dr. Ali. Its quite clear tp proceed with an application. Huge respect for you. Really great!
Brilliant! I am wondering if you can use Bayes theorem for probability? Since you can observe the paths taken by the ants.
the pheromone matrix depends on the length of the solution or the number of parameters of the problem ?
shouldn't the vaporization be quadratic ? since its spreading in 2d space
Incredibly well explained. Especially with the visual and mathematical examples. Thank you very much Mister Mirjalili!
I took the opportunity to subscribe to some of your udemy course. I hope, later this year, I will have enough time to learn more about this and the other algorithms.
Can i use it to find area have more children but not have school??!
