Maam ..please do more examples please maam
Pls upload a video of big m method with maximizing problem
Mam please do a video on revised simplex method
People like you should lead a revolution in education, I payed more than 3 lakhs to college, and yet everytime I come back to people like you. For operations research subject, my whole University students (around 200) students watch only your videos and not a teacher who gets a monthly payment of 1 lakh for nothing. Please join with few people like you and bring some revolution. I would have been happier if my 3 lkh went to you and youtubers who helped through these years. Please🙏🏻
I agree
Can we take -M
Please explain
@@ratbest1140 use -M if we have to do maximization
Can we take +S1 for maximization .
Ya u right real education is given by her without paying 💰 money . We are only spending money for the teachers who have no mean to us only they want money to us and then think go to hell.
The words that u had written in the first slide tell's me that from where u had got the knowledge..
That knowledge from him can make each and everyone understand easily..
God bless you mam
This video is very helpful for backbenchers in the classroom.

Watching your video is better than attending the class in university.
yeah !!
True
here we don't need your suggestion...so please keep your suggestion with yourself....

v bad preparation bro...tripura ka hu main😓😓😓
Thank you aunty, you have a big fan following in St Xaviers Mumbai
having online class is hard, thank you madam for this video!
You are better than my teacher, thanks a lot. I can easily understand from now on
Wish you were my teacher in college also. You've helped me tons. Thank you so much!
Thank you for teaching me a subject I thought I could never understand or be interested in.
Your way of teaching is good, it is far better to attend your video than that of my class.
Really, mam, you are an outstanding teacher. I really enjoyed a lot your all tutorials and got a lot of knowledge just in two days and know I am able to do my exam very easily and comfortably.
Love from PAKISTAN.
Chala clariti gaa chabutunnaru madam..... Superbb u have a bright future.....👍
Your teaching process is awesome, you will go to my best teacher list, thank you so much mam for this awesome lpp playlist, it's helping a lot ❤️❤️❤️❤️
I understood each and every concept of this subject by this channel thank you mam
Thank you mam for all the videos all your videos helped me in the last minutes for clearing my doubts and now i prefer your videos rather than the teachers in our university
Thank you mam
Most Worthful for the word "TEACHER" 💙💙💙
How can a teacher be so good at teaching? Irrespective of what I score on the exam, I will attribute my complete learning to you ma'am.
Mam I from Gujrat I see your your video Mam your are better than teaching our professor
Well explained .. Such a clean presentation.. Helped a lot.. 👍

Hiiu
Maybe this teacher she is from espana, her english it seems that espanish woman !!!
Watching your videos... I always remember my school teacher Sr. Flory .... Explaination and voice is completely like her ❤️🙏
Might help you:
instead of remembering each cj-zj condition and each M (sign).
Convert minimum to maximum
Max(w)=-min(z) and apply same step as maximum it will be easy for max and min process both. And you can do maximize
-Use always -M in function with artificial
-Use always Cj-Zj condition as same as simplex.
-Min +ve ratio
Tq for explaining I was confused by this only whether should we convert min to max in big-M or just take min with changed "m" sign and cj-zj
@@elinacooper9627 Can you explain it in detail, pls?
Can you please explain in detail?
Never knew learning LPP would be so easy. It was a great help!

Ur the best techer to teach any one in understanding way
This video is the best for exam point of view😀
very clean and easy-to-understand videos ..... i learnt whole LP by watching ur videos... great job mam..!!!
Mam thx alot ,, since a morning i didn't clear topic but now clear , awesome teaching ,,,
thank you so much... you are a an excellent teacher/communicator.
thank you your video made me got an A for my management science exam
You are best. i have understood without challenges. Explanation on point.
Really good presentation ✅ can’t thankyou enough mam ... saved the day ❤️
Mam ,really too good explanation ,Sir told in class but I didn't understand at any time ,but I search in you tube of your thumb nail,and then open it and watching the video ,I completely idea about this big method topic ,superb mam ,THANK YOU SO MUCH ,this coment is your thinking giving heart symbol or not in your mind ,mam no need that ,just done this your job ,and I support for further videos ,JAI HIND😇😇
Thank you so much 😊, All the best 👍
Mam, at 10:56 How did u know that 15-13M is the most negative one, without knowing the value of M (for eg. If M =1 none of the Cj-Zj will be negative)
bro check all the coefficient of M in Cj-Zj,you will find -13 is the most negative of all ,that is the main reason she choose it ,this is the rule mainly
M is a very large positive number. That is the assumption we take. So 15-13M is most negative value among them.
Take m=999999999.…...most -ve will be x2

my exam is tomorrow & here i'm :)
just excellent madam once we watch this video you will never forget the big m method
Thanks....mama..
Your videos are very helpful,thank you mam
thank u so much mam,,clear explanation
What a teaching madam .....TQ for learning us .your teaching is better than our sir!! keep going
whats the difference between minimization and a maximaztion problem. PLZ reply
(i)For maximization problem, the co-efficient of the artificial variable in the objective function should be minus M (-M ), for minimization should be +M
(ii) for maximization optimal condition is Cj - Zj = 0 or less than zero (-)
for minimization optimal condition is Cj - Zj = zero or positive value. Hope its clear now.
+Kauser Wise Thanks a lot Mam
wat about S? will they remain negative for both maximization and minimization probem in this method
and mam in both case surplus variables are minus(-s1 and -s2)
Kauser Wise yes please what about s?
thank you very much ma'am I just mastered graphical and simplex method in 2 days. thank you very much.
Call you tell me ,how did you take,-(10/3)m+10,as most negative no?.do we take assupmtion for m??... please reply as soon as possible!!
even i'm having same doubt!
For the big-M method, we assume that M tends to infinity.
Mindi Govinda, M is a very large positive number..so -10/3M is a very large negative number.
So that value is the most negative among all
@@cartoon5428 M is a very large positive number. So -10/3M is a very large negative number.
So among those values this is the most negative
for this qn 😍
thanq mam ...I just understood the big M method
Hi, 1 doubt. At approx. 10, you said that the Cj-Zj values are less than 0. But when we take the 1st one, 7-5M, imagining M=1, 7-5*1, 2. This is > 0. Please clarify.
yes if you consider M=1 then both x1 & x2 are +2 value so you can't find key column but when you consider M = 2,3,4,5,6....... then you can.
1st I have same doubt .
M is a huge number, consider is as being +infinity. Therefore following your example: 7-5M = 7-(5*infinity)= -infinity. To assign a huge value to M is the whole point of the Big M method
M is very large positive value bro
m is big
awesome.... taught in a very simple manner. very useful...
Why we put dashes on artificial variables,i dont understand :(
Why first A2 then A1 are gone?
When you have an artificial variable that is leaving out, you just do not need to calculate that column of artificial variable because you do not need it for anything, you can drop out that column (so u will not have to write dashes).
Thank you mam aap ne meri problem dur krdi ye (dusre log lodu minimum ko maximum me change kr rhe the lodu) THANKS
What do I put the value of M as if it's a maximize sum??
Do I put value of M as +M or -M
Also do I need to convert maximize equation to minimise or keep it as it is?
Negative M
Aur u can change it to minimise When u get the Optimal solution i.e Zj just changed The sign
I have seen many sums of minimilization and maximization where each and every time -M is only taken !! Then why mam have considered +M here?
@desioctane
Praise the lord ma'am
Your video helped me a lot thanks
How u consider that Cj-Zj < 0 .... put m =1,0 n u will get Cj-Mj>0....
Well here M is considered to be a very large number. Thus explained.
Thanks for such a nice video you helped me a lot in my or preparation
Mam pleaseeeeeeeeeee upload the Two Phase method...
Thank you so much, this was very detailed and easy to follow!
Love the way you say 'greater than and equal to' 😂
thats a South Indian accent
@@prashantgfx5786 I know
It's cuteee
@@samratalha. well ,couldn't agree more
Lol it's too cute when she says
i See you ma'am as a God
this was amazing
i followed complete playlist of LPP
thank you for saving us when professors failed to
💯
Thank u mam
I hope this online class is very well and excellent💯👍
We've been taught with zj-cj can anyone tell me is it wrong or not? Cause if it is my teacher has a lot to explain?
No its not wrong bro
But when condition is maximun you select most negative value to find key column vica versa( minimum - positive)
Well explained.. Itz helpful for mech student...
why did u consider the 15-13m is most negitive value tell mi onces
Because M is most positive no.
And if we subtract it than it become most neg no
Give M a very high arbitrary positive value. Like 10, the higher the coeff of M the more negative the overall sum will be.
20-12M isn't -ve
Love the way you describe and its soo clear thank you soo much 💞💝💕
yum*1+yum*2 = 3 yum :D
yum yum..

I was reading Comments while watching video ...and then I was wondering what you wrote "yum"..then suddenly she said yum..😂😂

excellent madam thanks for teaching complex problems in simple
Will I have to convert Min. z to max. z in the beginning ?
yes
yes thats why artificial variable has been introduced to solve the model
no , thats the two phase method .
You can solve the problem in either way.
If you convert min to max then follow all rules of max z like check Zj-Cj>/=0....and then multiply a - ve sign to your final answer.
Or you can proceed through min problem and check Zj-Cj
Big m method is for minimization problem...so if u got maximization problem then only u have to convert it into minimization and proceed further
The best explanation of simplex method 👍👍👍
How many of you watching
