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
Thank you sir first of all What shaheem was asking was this it would be R3-> 3R3-5R4 but according to Guass-jordan row operation the coefficient of R3 must be +1 so thats why the 3 is divided instead on the R4
Legends have it that whenever someone says no offense, means they wanna offend you!! 😅😅😂 When someone says simple method means is gonna be difficult 😅 did he just say is it clear?!! I hope is not clear 😂😂 that's the most Badass mathematician motivation u would hear!! 😅😅😅😅😅
I spent more than 1 hour trying to understand simplex method but your videos makes me understand it simple and clear.
"Smallest positive ratio. Ignore zero and ignore negative ratio." This really save my day! Thanks!
And brother you saved my 25 minutes🙂

Yes ❤
Simplex problems are not that Simple
Iska naam simplex nahi,balke complex hone chahiye tha
But he makes into simple
You are right sir 👏
Right 👍 not essay

Did not attend class the whole semester and this angel here just saved me. It's my last year and if i graduate I am coming back with a huge donation
Us bro us
Good luck; I hope you graduate!
Its my last year as well
Hopefully
@@usaidshahab4364 Good luck to you too!
Which country??
I am very appreciate. I was blowing up my brain for this topic but you teach me in 25 mins. Best wishes from Turkey to the best teacher
Rather naming it simplex it must be named with complex method
😂
💯😂
good teacher i understand your video in first time and you clear my all concepts.
Thank You Very Much Sir , You explained us in really easy way with point to point explanation, i like your teaching technique 💯🙌❤️

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!

i skipped the lecture where the teacher got to explain this so im learning it online now
bro got the best explaination on youtube. thank you bhai!
Thank u sir ❤ I'm confused first.....but your video makes me happy 🙂it's very simple
Thank you sir for your clear explanation
You are most welcome
Underrated channel for sure!
great explanation you saved me so much time, thank you!
I tried many channels for understanding simplex method now I stopped at your channel.
It's really nice
23:39 if u are so unlucky , It can go upto 4 tables 🤣🤣 So True Sir.
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"😂😂
wow i really understand than learning at school
SUPERB EXPLAINATIONNNNNNNNNNNNNNNNNNNNNNNNNNN SIRRRRRRRRRRRRRRRRRRRRRRRRRRR THANKKKKKKKK YOUUUUUUUUUUUUUUUUUUUUUUUUUUUU SOOOOOOOOOOOOOOOOOOOOOOO MUCHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
Hey I just viewed your video n all my doubts got clear in a easiest way tysm
The correct constraint is x¹, x², s¹, s², s³ >= 0.
Thank you, just 25mins i've understood what i needed to spend 2hrs in a lecture hall 😁
I had an issue with the R3-4R2 at first...i didnt know it was that simple💯
thank you i cant understand my prof in clg but you help me very much sir
sir i want to join in EKEEDA
😇😀😀😀😀😀😇😇😇😇😇😇
This is amazing!!! YAAAAYYYYYY!!! Best lecture on operations research evaaa
Very well explained 👌such a complex thing told so easily by sir 👌👌
I guess this is the best explanation that I'd ever get
6 hours to exam, bless ❤️
Thank you sir very well understood sir .
Amazing concept
Thanks a lot❤
Simplex* they named it.
😂😂
thank you please for this piece , I have understood it better learning with you
Can we use decimal instead of fraction for this simplex method??
Grateful to found this channel❤
Masha Allah super❤❤❤ Very much Helpful Video Lecture
Syed fayaz kashmir, India
I really love u, greetings from Venezuela.
Thank you sooooooooooooooooooooooo much sir God bless you 🤗
Thanks sir I understand it in only one video
Much respect from Nigeria
this video is the exact way whose my teacher has explained and i didn't understand, But with your explanation, i perfectly understand, Thanks
Might be the easiest explanation to simplex method on youtube...🍸👌
If we convert the max z into standard form then it should x1+4 x2+0s1+0s2 (3:09)
is this clear I hope it is not clear.. 😅😅😅
I understood it quite easy. Good work
Thanks sir uh make it really simplex 🤩
Sir your are incredible in solving this
Excellent explanation. Keep up the good work!
Thanks, will do!
thats so simple sir. thank u so much for the video
I am from Bangladesh sir❤❤❤tnk u so much ❤❤
Very easy method 😊... thank u sir❤
ayein?
😮??@@johnxina7496
He teach this very easily
Thank you so much sir, Made it simpleeee.
I’m so grateful for this tutorial
Thank you so much
This guy explained this in the simplest way possible
Interesting Prof. Please could you send us Decomposition method ?
Thank u Soo much sir kmaal explanation 👍
I loved the way of teaching!
Such a nice explanation sir🎉❤
Wow,this tutorial has made me understand simplex Tableau
This is simple and good
Thank you so much I have understand it and I want to know how can I get your video about big M method......
Very easy method.well explain sir. Thank you so much 💗😚
For step 1, what if both coefficients are the same negative ( i.e. -1 & -1)
I saw in a video whr the a minimization problem had the constraints to be lesser than or equal to
Can someone answer why x1 is able to be zero as I thought the constraints say that x1 has to be greater than 0
05:42 Sir why you didn't put S3 here??
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
22:18 "I hope it's not clear" 😂😂😂
Needs full attention
splendid. Thankyou sir
😂😂no need for studying notes watch this man a day before the exam you are good to go❤
I watched like 7-8 videos but none of them teached me about the r3-5r4 whatever....
Thank you sir first of all
What shaheem was asking was this it would be
R3-> 3R3-5R4 but according to Guass-jordan row operation the coefficient of R3 must be +1 so thats why the 3 is divided instead on the R4
If it still confuses you, watch any video on row operation method that should clarify what he did
Ever best learning experience..
Amazing sir
..thank you to clear my doubt in first step
You can explain algebric form please
thank you so much 😭😭
Please explain why you consider s1 and s2 positive without mentioning s3???
13:25.....for my reference
Legends have it that whenever someone says no offense, means they wanna offend you!! 😅😅😂 When someone says simple method means is gonna be difficult 😅 did he just say is it clear?!! I hope is not clear 😂😂 that's the most Badass mathematician motivation u would hear!! 😅😅😅😅😅
LPP? More like "You're the G-O-A-T!" 👍
Sir plz make a video on two phase method
OMG this is amazing 👏
Sir can you put a video for 2 phase method
Great explanation
this is an Amazing explanation. Thank You
Understanding good 👍😊 CA
Best explanation👏
Why is s3 not included at the last part of writing the inequality? Time stop: 5:45
Amazing explanation, thank you very much sir
