This man is the Bob Ross of Algorithms. Just straight up vibing, providing the easiest to follow explanations at a pleasant pace. My own Analysis of Algorithms professor's notes look like ancient forgotten text compared to his. I cannot thank you enough Abdul Bari.
I was getting a very soothing vibes while watching the video and I was trying to reconcile when before I had experienced such bliss.. Because of you, it clicked almost immediately that he is indeed Bob Ross. It is a quite hilarious yet perfect comparison. XD
My professor literally copies all his examples and notes, and yet no one can understand him, but Mr. Abdul Bari's explanations only needs to be heard once and all the concepts get cleared. Thank you for all of this Sir.
Your teacher is also putting all efforts but at that time you are not put all your efforts to understand ,but at exam time you putting efforts that why you understand better all these topics are in Horowitz Sahani ,Bari is good teacher .
sir just loved your approach.You cleared the concept of matrix multiplication..then you did the same with divide and conquere and then you told how normal multiplication is better because both have same time complexity but different space complexity..and finally you told how strassen reduced the time complexity from n^3 to n^2.81.Just loved it!
Pretty crazy that a 0.19 reduction in exponents is so good. Assume n = 1000, then we're talking a billion operations compared with approx 287 million operations!!! that's very significant
I'm heartly wishing u a happy teachers to the best teacher ever in the world...u should be given some award for doing this job greatly... thank u soo much sirr🙏🙏
Thank you for the video. The explanation was very clear and straight-formward. However l wished that you could explain more at the last 5 minutes of the video.
When I was seen my book omg how can I done with this but when I saw u r videos I feel too relax and I felt and i learn subject from u sir thank u sir 🥰
Sir I wish you got a lot of subcribers. I will try subscribe as much I can. When a useless youtuber can get millions of subcriber so the teacher like you deserve more. Thank you sir. Everu cs student should subscribe you.
Thank so so much for the lecture. I have a question, does anyone know any books or websites to do more exercises for algorithms? I get the concept but I need to practice more
I've got a question...given that Strassen's or the divide and conquer needs to have matrices in perfect powers of 2, As n gets larger, wouldn't the iterative method be faster than Strassen's unless we're at a 2^n*2^n due to the fact that the size of the matrix needs get larger/padded by 0s? or am I missing something?
Start from 20:53. As the first 20 mins are just about Normal matrix Multiplication O(n^3) and Divide and Con. Also, take the same TC with extra space. Thanks, me later!!!
21:36 I applied exact same formula but couldn't get the correct answer. Every element is correct except c21 and c22. I've rechecked the answer thrice and all the steps calculated are correct. And also I've seen different type of formulas. So please can you check whether the formula that you've provided is correct. Please let me know if I'm wrong. TIA

Looked at like 4 other videos on this algorithm. I finally got it after this one. Thank you!

Thank you for ur lecture I'm from Saturn we watch ur tutorials there helps a lot in school
I was reading the same topic in Introductions to Algorithms book. Your explanation is much better than the explanation in the book.
You are a boon the CS mankind, Sir! ☺ Thank you for everything!
The best english off all the Indian teachers teaching on youtube.
Just go to edureka first
Best teacher in Computer Science Field👏
Please take this the right way, I love how you explain it like I am 5. So simple.
Really helpful for all the students who are writing sem exams at present 👍

Incredible, love all of your videos!
Keep this video's as long as possible it helps students to understand easily
Such A great explanation and the way of teaching is amazing. thank you so much for uploading these videos.🙌🙌🙌👌👏
simple and easy-to-understand your explanation is. Complicated and hard to follow, my professor's explanation was.
I am from tear-2 college but you are far far better than my college's prof.s
Thanks for these wonderful videos, these videos are a fuel for my career, Once again thanks man
My semester finished before your video.
Awesome explanation Sir
The teaching is inspiring and easy to understand! I really appreciate it, thanks!

Happy Teachers day sir🎉
Self study is better with this class
The more I go deep into algorithms, the more I start appreciating Mathmatics.
Thank you sir
Method of another people confused me
You explained accurately and in short term 🤗🤗🤗
Happy teachers day sir, Mucho Appreciated!!
You are the Best Teacher

Thank you so much Sir 😇...

He is from India too
You made it so simple to understand
such a good lectures it help me very well in my study
Thank you. Vey clear. So how we came up with the 7 equations at 22:43 please?
How to derive strassen's formulae without memorizing it??
To derive Strassen's formula you need to think like Strassen :)
I believe he spent years to come up with it

Are these PQR formulas need to be learned??

Thank you sir. Great explanation.
I've got a question...given that Strassen's or the divide and conquer needs to have matrices in perfect powers of 2,
As n gets larger, wouldn't the iterative method be faster than Strassen's unless we're at a 2^n*2^n due to the fact that the size of the matrix needs get larger/padded by 0s?
or am I missing something?

8 to 7 multiplication
Greedy to strassen
Multiplication has reduced but addition increased
Addition takes less time than multiplication
