A simpler approach is to use the new Cj value to subtract from the Zj row of the solution simplex table and check if the result (after subtraction) on the Cj-Zj row remains zero or -ve for a max. and zero or +ve for a min. problem. If the optimality check shows that optimality will change then proceed with the next iteration
While I was solving the problem at the beginning of the video, I always find that basic variables are relatively x1,x2,s2 NOT S3. Are you sure about that, if I have a mistake, could you please explain it ?
The constraints are: 2 x1 + x2 2 x1 + x2 + s1 = 20 x1 + x2 x1 + x2 + s2 = 18 x1 + 2 x2> = 12 ----> x1 + 2 x2 + s3 - A3 = 20 The solution is x1 = 2, x2 = 16, s3 = 22. The solution is correct, because if you substitute the values of the variables in the equations on the right, you will find that the constraints are satisfied.
Awesome explaination Sir, May I know which editor are you using for making this viedo, I also interested to make videos of Mathematics so please give us the name things which are you using for making videos and some suggesions which is helpfull for us Thank you Sir

Wow u are amazing , thank you very much,
I'm from Iraq and ur video was very helpful for me , thanks again :)
thank you for these videos, you keep saving my grades!
For all who are asking about the basic variables and how to choose them you need to solve this system using simplex method
Very well explained, thank you!
Thank you for this video! Which calculator did you mention in this video?

Thank you Sir
Great video. Can you please tell what sw was used to make this video?
Vyond
great explanation thank you, but I guess Cb=(7 0 4)is not correct it suppose to be Cb=(5 0 4)
I promise you to review your comment well, and in case you made a mistake, make this video again.
Greetings and thanks
how do you know which to use for b ?
How to chose B ( basic variables) i couldn’t Understand 🙄!!
Hello sir, How to choose Basic Variables? I could not understand it.
Hi you did not explain why you put A3 and what is this ? And what is MA3 ? This is too confusing
if optimal tabelu isnt given only problem

what is with the music, very distacting
Sorry... :(
It's not so distracting
Tough video

thank you very much bro, you helped me the fuck out!!!!!
