Thank you. The technique you have used to present your presentation is very good🙏❤
I had studied this topic in college and understood it, but I wasn't satisfied with the method. However, I found this approach to be very easy and effective.
Okay this video is amazingly explaining the simplex method, thanks :)
The most simple tutorial on simplex method 👌
Quick and to the point. I love you, man. ♥
nice video, it's the clearest explanation I ever seen. Thx
first-class-tutorial, thank you!
This is honestly a way better video than the one where scott gives me ASMR
Simplex method is not simple, but you make it simple. Thanks a lot
I love you, thank u so much you have saved my exams! Much appreciated!
he saved me from everything. meng i love u
Great video! You deserve applause!
perfectly clear! helped me a lot
your explanations are very clear, Sir. Thank you so much!
My pleasure, Leonard. Thanks.
Thanks to you I passed an exam
Very wonderful video
and straight to point
Bro. thank you so much! keep it up!
Nice and simple explanation, well done
clean and concise thanks 👌good for going through step by step along (note: this is for maximization, minimization is a little bit different)
For Minimization you need to change the following:
- select column with _most negative_ cj - zj number instead (first in case of equals)
- still select row with the smallest positive ratio value
- optimal solution is found once all cj - zj numbers are positive when minimizing instead of negative. (greater or equal to zero)
Everything else stays the same. also note that the cj don't change throughout the iteration so no need to check for them :)

Thank you joshua for clearing the topic. My teachers are capable to teach the subject can't control the class so was having trouble in understanding the concept thanks once again, it is a request that anyone who is reading this comment go through this video 2-3 times for more and more clarity 🙌
Thanks for your note and recommendation, Aniket.
thatwasamazing
Thank you
thumbs up👍👍
I have questions, how about if i happen to have the net values in the pivot of S1, should i consider to change the basis with S1. And another question, if the net values are negatives so i choose the most positive one right? I mean the less negative, but if it happens to be at S1 would it be a problem? Or maybe if the net line were all negatives i choose the value of the b and it has finished?
On selecting the pivot row do we only take min positive integer or the least of value in general
