I've summarized the process below:- Slack variables used should be = number of constraint equations In the standard form, the greater than equal to sign of the constraint becomes just an equal sign. Write objective function such that Z = 0 Table layout is BCRR (Basic variable, coefficients of ‘’, RHS, Ratio) In the table, in the top row (associated with ‘Z’), Find most negative number, associated column is the KEY COLUMN Now do ‘RHS/corresponding key column value’ Check for smallest POSITIVE ratio This gives you KEY ROW So basically first you have key column, then row (remember is as KORO) Intersection of Key column and row gives KEY ELEMENT. Now, we make a new table similar to the earlier one, we want to make sure KEY ELEMENT = 1. So we DIVIDE the KEY ROW by KEY ELEMENT. (don’t do key row/ key row) Using the new key element which is ‘1’, we make sure the entire key column is 0 (apart from the value of key element) The SMART thing that the tutor does is, he makes the key column as 0 (apart from key element) before starting calculation (check minute 15:46 in the video) During this operation you should edit in the layout BCRR (but except the last column named ‘ratio’) Now the key row will leave and be replaced by the key column. (check minute 20:50 in the video) Now if the column with ‘Z’ has no zeroes, then we can stop. Now, check value of ‘RHS’ column for each value, i.e. Z, x2, etc
That emphasis on the smallest positive ratio at 11:18 is something a lot of tutorials leave out. The examples I've seen don't exemplify this case as they usually are all positive ratios so I appreciate the clarification.
I watched 2 digit videos to understand this Simplex method... And this guy made me understand without replaying the video.... Thank you for being a teacher. You are the best

Thank you so much. I completed my second year without understanding the Simplex method. I thought I was done with it only to find it again in third year. I came across this video. WOW!!! Thank you so much. You are the best!
You are the best teacher I have come across for this topic and I will be checking out your other videos. Thank you very much, may you continue teaching others. You truly are making a great impact. Best wishes!
I watched it 3 times and spent almost more than one hour and Alhamdulillah finally I got it. Linear is not Linear as it's name 😂, It's very complex 😅. Love from Bangladesh🇧🇩

if the question is MAX type then no need shift them to the left side it will results in wrong optimal value of max Z. It is only done when the question is min type when the surplus variables are used. I have done it the answer is wrong. 4:20
"Smallest positive ratio. Ignore zero and ignore negative ratio." This really save my day! Thanks!
And brother you saved my 25 minutes🙂
I spent more than 1 hour trying to understand simplex method but your videos makes me understand it simple and clear.

Us bro us
Good luck; I hope you graduate!

Ha sir ji aapka bahut bahut dhanyawad sir please or aesa video banaye
So good now am clear
Thank you so much. I completed my second year without understanding the Simplex method. I thought I was done with it only to find it again in third year. I came across this video. WOW!!! Thank you so much. You are the best!
what a great man,who saved my optimization course. what a hero!
You are the best teacher I have come across for this topic and I will be checking out your other videos. Thank you very much, may you continue teaching others. You truly are making a great impact. Best wishes!
You're very welcome!
Rather naming it simplex it must be named with complex method
😂
💯😂
Sir actually your teaching is so good. I was really struggling with this concept but now its damn clear!! Thankyou 😊
good teacher i understand your video in first time and you clear my all concepts.
Best and easiest method of teaching sir
Hats off to your efforts

Thank u sir ❤ I'm confused first.....but your video makes me happy 🙂it's very simple
I watched it 3 times and spent almost more than one hour and Alhamdulillah finally I got it.
Linear is not Linear as it's name 😂, It's very complex 😅.
Love from Bangladesh🇧🇩
"linear is not linear"😂😂
This is amazing!!! YAAAAYYYYYY!!! Best lecture on operations research evaaa
Wow finally I understood
I'm still struggling and I found this tutorial 2 hours after my exam
Oh man I'm sorry. I hope your next exam goes well!

Thank you sir very well understood sir .
Such a nice explanation sir🎉❤
Much respect from Nigeria
Very easy method.well explain sir. Thank you so much 💗😚

If we convert the max z into standard form then it should x1+4 x2+0s1+0s2 (3:09)
Thank u Soo much sir kmaal explanation 👍

Clearly explained!!!
He teach this very easily
Thank you so much sir 💞☺️
Super talented, sir❤
Great Sir.🤍💙
Great job!
thank you so much 😭😭
This is simple and good
Can we use decimal instead of fraction for this simplex method??
Great explanation
Thanks for the video :)
My pleasure!
Amazing explanation, thank you very much sir
if the question is MAX type then no need shift them to the left side it will results in wrong optimal value of max Z.
It is only done when the question is min type when the surplus variables are used. I have done it the answer is wrong.
4:20
Very clear video
Thanks you are the best❤
Thank you so much I have understand it and I want to know how can I get your video about big M method......
Interesting Prof. Please could you send us Decomposition method ?
