Simplex problems are not that Simple

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!

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.

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

I'm still struggling and I found this tutorial 2 hours after my exam

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

Simplex* they named it.

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

i skipped the lecture where the teacher got to explain this so im learning it online now

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!

Rather naming it simplex it must be named with complex method

Thank You Very Much Sir , You explained us in really easy way with point to point explanation, i like your teaching technique 💯🙌❤️

Sir actually your teaching is so good. I was really struggling with this concept but now its damn clear!! Thankyou 😊

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🇧🇩

Can we use decimal instead of fraction for this simplex method??

Wow finally I understood

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!

23:39 if u are so unlucky , It can go upto 4 tables 🤣🤣 So True Sir.

good teacher i understand your video in first time and you clear my all concepts.

Thank you sir for your clear explanation

😂😂no need for studying notes watch this man a day before the exam you are good to go❤

6 hours to exam, bless ❤️

Amazing concept Thanks a lot❤

I had an issue with the R3-4R2 at first...i didnt know it was that simple💯

Thank you sir very well understood sir .

I tried many channels for understanding simplex method now I stopped at your channel. It's really nice

I watched like 7-8 videos but none of them teached me about the r3-5r4 whatever....

Thank you, just 25mins i've understood what i needed to spend 2hrs in a lecture hall 😁

OMG this is amazing 👏

Underrated channel for sure!

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 u Soo much sir kmaal explanation 👍

Best and easiest method of teaching sir Hats off to your efforts May God bless you Sir

Thank you so much I have understand it and I want to know how can I get your video about big M method......

Thank you sir 🙏

thank you for your generosity! it was really helpful!

Needs full attention

Very well explained 👌such a complex thing told so easily by sir 👌👌

thank you i cant understand my prof in clg but you help me very much sir sir i want to join in EKEEDA 😇😀😀😀😀😀😇😇😇😇😇😇

I really love u, greetings from Venezuela.

I guess this is the best explanation that I'd ever get

It's clear because my brain has got excessive amount of neurons....

Thanks sir I understand it in only one video

Thank you very much sir🎉❤

Thank you sooooooooooooooooooooooo much sir God bless you 🤗

22:18 "I hope it's not clear" 😂😂😂

Thanks sir uh make it really simplex 🤩

Thanks for the video :)

SUPERB EXPLAINATIONNNNNNNNNNNNNNNNNNNNNNNNNNN SIRRRRRRRRRRRRRRRRRRRRRRRRRRR THANKKKKKKKK YOUUUUUUUUUUUUUUUUUUUUUUUUUUUU SOOOOOOOOOOOOOOOOOOOOOOO MUCHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

Masha Allah super❤❤❤ Very much Helpful Video Lecture Syed fayaz kashmir, India

Might be the easiest explanation to simplex method on youtube...🍸👌

Excellent explanation. Keep up the good work!

Thank you ❤

Thnku so much sir 🤩

Hey I just viewed your video n all my doubts got clear in a easiest way tysm

This is amazing!!! YAAAAYYYYYY!!! Best lecture on operations research evaaa

Understanding good 👍😊 CA

Grateful to found this channel❤

thank you please for this piece , I have understood it better learning with you

I understood it quite easy. Good work

Thank you so much I just understood the concept now

Here 2 hours before my exams.

Very easy method 😊... thank u sir❤

I am from Bangladesh sir❤❤❤tnk u so much ❤❤

Thank you so much sir, Made it simpleeee.

splendid. Thankyou sir

Very easy method.well explain sir. Thank you so much 💗😚

He teach this very easily

this video is the exact way whose my teacher has explained and i didn't understand, But with your explanation, i perfectly understand, Thanks

thats so simple sir. thank u so much for the video

Such a nice explanation sir🎉❤

I saw in a video whr the a minimization problem had the constraints to be lesser than or equal to

If we convert the max z into standard form then it should x1+4 x2+0s1+0s2 (3:09)

Sir your are incredible in solving this

I’m so grateful for this tutorial Thank you so much

very good

LPP? More like "You're the G-O-A-T!" 👍

Please explain why you consider s1 and s2 positive without mentioning s3???

thank you so much sir...

Wow,this tutorial has made me understand simplex Tableau

thank you!!!!!

Thanks

Great explanation

Thank u sir

I got it in half hour ❤

05:42 Sir why you didn't put S3 here??

Thanks sir

The correct constraint is x¹, x², s¹, s², s³ >= 0.

this is an Amazing explanation. Thank You

Thank you so much sir

Best explanation👏

Great job!

Is difference if we add slack ( S1,s2..)?

Is this simplex method in tabular form

Amazing sir ..thank you to clear my doubt in first step

Ever best learning experience..

I loved the way of teaching!

Heart' touching ❤❤
