Mam, Tomorrow is my exam. I watched your all videos today I.e. simplex method, big m method, graphical method, duality, transportation problems and assignment problems too. While watching your videos i no need to revise. These videos are perfect for me. Thanks a lot😊🙂
Construct the dual of the following Problem and solve both the primal and the dual. Maximize Z = 2x1 + x2 Subject to - x1 + 2x2 ≤ 2 -x1 + x2 ≤ 4 x1 ≤ 3 x1, x2 ≥ 0 Solution using the primal problem. Corner points (0, l), (2, 2), (3, 1), (0, 0), (3, 0) Z = Hence the optimal solution is x1 = 3 x2 = 1 Max Z = 7 Now, using Dual problem The Dual of the given primal is Minimize W = 2Y1 + 4Y2 + 3Y3 Subject to -Y1 + Y2 + Y3 ≥ 2 2Y1 + Y2 ≥ 1 Y1, Y2, Y3 ≥ 0 Express the problem in standard form W = 2Y1 + 4Y2 + 3Y3 + 0S1 + 0S2 -Y1 + Y2 + Y3 - S1 + 0S2 = 2 2Y1 + Y2 + 0Y3 + 0S1 - S2 = 1 The first simplex table?
When an objective function is of minimization type, you correctly said that while converting it to a maximization problem, the objective function is to be multiplied with -1. However, it is better to rename the new objective function as z*, which is nothing but -z. This can be done to avoid confusion among students. The steps have been explained very properly and nicely. Thank you.
Mam you are great teacher But I want to give some suggestions Please upload scanned pdf of your notes in drive and share the drive link in description It would be very helpful Thank you ☺️
Thank you very much for explaining it in One of the easiest way.. it's easy to learn. Today is my test and I'm watching this 😀 I'm pretty sure I'll be scoring good marks. Also your voice is very soothing that makes me feel relax 💞
Nice concrete and helpful lesson without mistakes and very good explanation 👍💪👏 I understood all, I saw many algorithms in many kinds of languages and R is very good
Tq very much didi I am getting nerves I thought I couldn't pass this peppers but I found and search its realy help for mi and understand very well all method I like ❤😂
मैडम जी आप बहुत ही अच्छा समझाती हैं👌👌हम छात्रों की तरफ से आपको बहुत बहुत धन्यवाद! Note--Mam 1--1 page me likh kar kya karti hongi Aisa kariye aap kisi copy me samjhaya /bataya kariye Jisse ki 1 notes bhi bn jayega aur page kharab km honge
maam agar Zj - Cj, -ve aye to kya same simplex method jeisa hi solve karna padega (pehle key column nikal ke phir min ratio se key row nikal na)?? Yaa uss me bhi XB ko priority deke pehle key row nikal na padega, fir max ratio se key column nikal na padega??
Mam Aap Ne Toh Previous Video Mein Bataya Tha Ki ' Dual ' Mein Kaise Convert Karte hain , But ismein Toh ' Dual ' Mein Convert Karne ka process alag Hai.
Mam mai ye woh wale cross multiplication wale method se kr rha tha..... 2nd iteration me..... X2 pr aap ka answer 1 kaise aaya mera toh 4 aa rha h iss ki wajah se zj - cj me ek negative aa rha ah..... 😢😢😢.
Hey mam I'm little bit confused and I hope that you will clear it.. Now the confusion is this..ki dual simplex solve krne ke liye sbse phle Lpp ko dual form me change krna hota hai..iss question me apne kyu nai kiya bss yahi janna hai..plzz ans. De dijiyega

Ok so how did it go ??
Your lecture is really very helpful because I prepare LLP from your video in one day which made my semester exam very well.
LLP nhi LPP 😂

Construct the dual of the following Problem and solve both the primal and the dual.
Maximize Z = 2x1 + x2
Subject to - x1 + 2x2 ≤ 2 -x1 + x2 ≤ 4
x1 ≤ 3
x1, x2 ≥ 0
Solution using the primal problem.
Corner points (0, l), (2, 2), (3, 1), (0, 0), (3, 0)
Z =
Hence the optimal solution is
x1 = 3
x2 = 1
Max Z = 7
Now, using Dual problem
The Dual of the given primal is
Minimize W = 2Y1 + 4Y2 + 3Y3
Subject to -Y1 + Y2 + Y3 ≥ 2 2Y1 + Y2 ≥ 1 Y1, Y2, Y3 ≥ 0
Express the problem in standard form
W = 2Y1 + 4Y2 + 3Y3 + 0S1 + 0S2
-Y1 + Y2 + Y3 - S1 + 0S2 = 2 2Y1 + Y2 + 0Y3 + 0S1 - S2 = 1
The first simplex table?
Subject ka name toh pata h n bhai 🤣
🤘🤘 super SE v uper ... Ek bar lecture attend kr le koi v apka ... to dubara dekhne ki v jarurt ni h mind m chhap jata h .... Good ....great job
Finally i found AEM chapter 5 simple solutions one day before exam ......thank u so much mam for easy explanation 👍🏻

today is my exam and this helped me alot tnq so much mam🙏.
Finally a video that saved me during my exams!!!
Thank you so much for this video!
Are Bhai bolega ki mujhe agar xb positive he all and zj- cj negative he all tab xb me konsa ku silect karenge
Just one word................
Awesome 🔥🔥🔥
thank you mam by watching your videos, i get confidence for my exams tomorrow you from the bottom of my heart
Nice concrete and helpful lesson without mistakes and very good explanation 👍💪👏
I understood all, I saw many algorithms in many kinds of languages and R is very good
thanks for the video; selection of incoming and outgoing vector is pretty easy with ur method
mam,simplex method and dual simplex are same????should'nt we convert to dual first?
Ma'am Thank you so much....
great explanation
its very helpful for us.... in our M.Sc. Exam.. God bless you ma'am
What if xb>0 but in zj-cj we have negetive
JzakALLAH Maam 4r sharing knowledge nd mashALLAah ur method iss so good nd easy way.💜💜💜💜
Mam ap bhut bhut bhut jyada achaa padhati hai
Aapke videos dekh kr sare doubts clear ho jate hai...🙏😊😊

I watched your operation research series videos. All videos are very well and helpfull. You have cleared all confusions. Thank you. ✨👍👏👏☺️
7:44 It's Really very Helpful.
Thanks Didi❤
As per rule But in dual simplex method we have to convert minimization type n?????
And mam why you have converted into maximization type???
Will we not convert question to canonical form and then dual form like you explained in lecture 15 and 16?
Thanks, this video is a saviour, I've my test in the next hour😅
Mam your teaching way is awesome and all topics explained in detail manner please start lacture series for upsc mathamatics optional
LOVE YOU MAM KUMAR,PIYUSH,HARSH,HARSHIT
आपका बहुत बहुत धन्यवाद 🙏🙏 मुझे बहुत अच्छा से समझ मे आया ❣️मेरा मार्च 2023 में PG 3Rd semester का एग्जाम हैं !
Mam simplex method m constraint m less and equal to hi hota h kya jisme greater than hoga use dual simplex se krna h?
Thank you so much ma'am. Your video is really amazing ❤
The way you teach everything is understood easy thank you so much for the video maam
Ma'am, Apki Video Bhoot achi lagi main ny 2 bar like kr dia hy.
Nice video mam each portion explained well
Nice explaination mam. can you tell me in which state you are living ?
Bhot bhot thank you mam you are exam sever
Thanks for uploading mam u'r way of explanation is awesome
Lpp ka pura syllabus kabar ho gaya , thank you mam
Good teacher!!!
I love you thank you very very much mam 😌
Thankuh miss bhut accha explain kia aapne
mam your handwriting is so clean i want one just like yours
Simplest ,easiest 💐
Isme cj- zj bhi kar sakte hai nj zj
Thanks youhh ...mam dual simplex method or dual simplex algorithm same hai ya ...aalag hai
Bhut acha smjati ho ap mam❤
Tysm ma'am
Agar kal ke paper me pas hoti hu to uska sara shrey apko hi jayega ❤️ thanks mam
Mam Aap Ne Toh Previous Video Mein Bataya Tha Ki ' Dual ' Mein Kaise Convert Karte hain ,
But ismein Toh ' Dual ' Mein Convert Karne ka process alag Hai.
Thank you ma'am, very helpful for us average students 😊
Mam please make a video on sensitive analysis mam please please bna Dena mam becoz your way of teaching is very good
Very helpful lectures 🌹
Mam agr key column select krte hue tie ho jae to kya krna chahiye?
Means agr x1 or x2 ki maximum ratio same aa jae to kya kren?
Thanks Mam❤️😍🙏😍❤️
thanks, perfect video :)
Mam,
Simplex Table & Dual Simplex Method equal he kya..
Same process use hota he ?
No
Great mam.khush rahain
Very nice explanation mam ।।।thanku
Isse artificial variable and surplus variable add karke bhi kar sakte hai na
Mam u r explaining vry good
I think this is the lecture of SIMPLEX METHOD and DUAL SIMPLEX is a combination of duality and simplex method
Helpful video thanks mam
Thank you so much ma'am for this fantastic lacture 🙏🙏
Well defind
very nice teaching skill
In step 3 said xb>=0 and zj-cj>=0 then terminate if xb0 and zj-cj
Mam is table mai ratio and solution ki row nahi aayegi kya ?
Outstanding. Video
Mam ye minimization wala mujhe matrix method se Krna h
Aapne matrix method ke upar video nhi bnai h?
Mam mai ye woh wale cross multiplication wale method se kr rha tha..... 2nd iteration me..... X2 pr aap ka answer 1 kaise aaya mera toh 4 aa rha h iss ki wajah se zj - cj me ek negative aa rha ah..... 😢😢😢.
Mam isme ratio minimum lena hota hai according to Krishna publication of lpp and linear algebra
Hey !
Mam can you explain ,what to do if while choosing the entering vector we get (1/0) form and any one of ∆j>0
Thankyou thankyou so so so much 😊
Gorgeous explanation !
Thank you for your efforts ❤️🙏👍
Mam hame kb initial table wala solve krna h Or kb w supposed kr k krna j
Hey mam I'm little bit confused and I hope that you will clear it..
Now the confusion is this..ki dual simplex solve krne ke liye sbse phle Lpp ko dual form me change krna hota hai..iss question me apne kyu nai kiya bss yahi janna hai..plzz ans. De dijiyega
Lots of respect for you mam❤
Ma'am between -2 & -4 , -2 is the most negative value not -4.... correct me if I'm wrong
Mam aap jo( _5)+(-5)= 0 liye ho wha pr 10 aayega
Nice Explanation
Your lectures is very helpful ❣️
for dual simplex method we don't need to convert it to dual form ?
Ma'am why didn't you convert the primal to dual form before solving as it is a dual method
Yes
Very nice, thank you 😊
