In this case, higher is better on both axes. Arent the rectangles drawn in the incorrect direction? If you would pick C, and draw the rectangle from there (to the right upper corner that is), you would know by which points it's dominated straight away?
Can AHP be used to solve multi objective problems? The user can perform a relative rating of criteria and then a benefit score can be calculated that gives you the best option ranking. Any thoughts?
Is it possible to optimize variables such as speed, handling etc. directly or do you have to have a function that describes how they relate to each other, and then you optimize that function?
Typically speed and handling are the objectives, and the variables are what determine these objectives. You can optimise the objectives without defining any relationships between them, however, it's often beneficial if you have auxiliary knowledge about the problem (e.g. knowledge about the desired trade-off).
Thank you Dr. Rostami. I have 7 related variables - 4 discrete, 3 continuous, each of the same size n. They are intuitively related but it's hard to formalize that relationship quantitatively a priory without introducing subjective bias. I am comfortable with lexicographic preference ordering though. I am interested in identifying a set of non-dominated, pareto-optimal solutions where 2 of these variables are optimally maximized and 5 of these variables are optimally minimized. How do I go about: a) identifying appropriate optimization algorithm for this problem, and b) how do I formulate / setup this problem in Scipy/PyGMO etc. all of which seem to want a functional formulation? Thank you so much for your time and help.
I am working on one of the max min problem. To solve this problem, I am using fminimax function under MATLAB. But I got stuck on a point in it. The initial value(i.e. x0) which I am passing into fminimax function and the final result(i.e. x) given by it are coming same. I have tried by changing the value of x0, still x is coming same. What should I do to get desirable result?
i ve a prbm with two maximizing energy nd other one minimizing cost objective sir, am not havg any idea abt mop, help me sir . which software is easy to solve this model
Hello Ênio. Your comment prompted me to create and publish an unplanned video, you can find it here th-cam.com/video/YFgtbxt7yhE/w-d-xo.html. I hope you find it useful! All the best.
thank you . this problem can be adapted for "the heterogeneous cluster"? - each node in cluster has a cpu and a storage capacity .. (in this case two objectives to satisfy simultaneously)
I'm glad you found it useful. I've had a few requests for a video on NSGA-II - is there a particular part of the algorithm which is difficult to understand?
thanks for your prompt response! sure, I need am not clear on NSGA-II, especially for more than 2 objectives with more than 3 decision variables for each. thanks again

Thank You! I've been trying to understand how Pareto dominance works for a couple of hours now and this video finally helped me understand.
very well explained, please upload more videos on this topic...
This presentation is clear understanding of single and multiobjective optimisation problems. Waiting for more videos
The very best. More videos please specifically on multiobjective optmizations.
Brilliant video, very well explained. I really hope that you can upload more about A.I.
Thanks a lot sir it was so helpful i look for the following vidéo to solve the multiobjectif problem
thank you! sir, please make a video on the comparison between single objective and multiobjective GA's and their applications
Thanks a lot very good introduction to Multi-Objective Problems
amazing and so helpful! thank you so much
Nice way to deliver concepts

great explanation. thank you so much
You're welcome!
Thankyou..
Extremely well explained. Many thanks!
My pleasure - thank you.
amazing explanation !!!
That is a very well explained subject. Could you please do a video on representation of solutions in evolutionary programming?
Thank you, It is very well video.. very Nice..
Thanks a lot Sir, it was extremely helpful
But what happened to stick people population ??!
Please make a video on selection strategies soon.
that's very nice, thank you.
and can you give some explanation on non-dominated sorting genetic algorithm?
a Very good explanation,would you mind to provide more details about Pareto front optimization with N -Dimensional
Well explained. Can you make a video on NSGA-II?
Just brilliant! Congrats!
Nice work. Can you please make a video on one can use multi objective problem for ensemble classifier selection ?
Another great video!!! Waiting for the next in series
Brilliant

Sir, this is a good video above all videos on Pareto optimal concept. plz can u explain, how to get the best solution from non-dominating solutions
Sir, I'm missing your videos like this =(

Love you sir

how to solve two maximize one minimize function siram not havg any idea abt mop, help me sir .
Very clear ！ thanks
Very nice sir, help me out with the assignment :D
👍

Narrarion too slow, primary school students won't be learning GA, so consider the audience.
Thank you.
