If anyone has confusion try this! Find ratios of each row(by dividing solution to key column value) and select least positive value from ratios and that particular row become key row Then proceed further
nice explanation madam because i forgot all this methods when my teacher i said i recollected this methods by seeing this videos thanks once again helped in my degree examination very lot
Thank you so much ma'am for existing in this world our college sir first study from you and then get told us to watch your videos the reason behind the sum is lengthy and is too bored to solve sum on board . Once again thank you ma'am you're angel for our sir 🙏🙏
I think I should pay the fees otherwise it will bad for not getting the value of her time although I know no money can be comlared to the value of your method and time
You do very much easy problems, try doing tough one nd explain about the easy one.. You do vice versa! If possible tell us about 3 constrain which contains x1 x2 x3 x4..
@kauser Wise In greater than type we need to use surplus variable and artificial variable..*not slack variable mam...by the way your teaching is super mam
U do very easy problems its easy to understand steps but if tough problems come cant do this type like 3 constraints Please do tough problems and explain in easy way to understand
Good helpful tutorial. Appreciations :) but I have only 1 question that if it would have been a maximization problem that what would be the changes in the solution and conical form or model? Answer would be highly helpful and appreciable.
Hello mam, i have just one doubt In this video you have said that for finding the key row we need to find the most positive value whereas in the simplex method we use the ratio and then find the smallest ratio to decide the key row. Though there is no conflict in this particular problem between the two methods, in some problems the conflict may occur, so could you please tell me which method should be followed?
Yes mam!...me too have same doubt.....i solved questions before watching your video ..and for optimal solution all Zj-Cj>=0 but according to condition you applied cj-Zj for optimity ,,we should have Cj-Zj
Hello Ma'am, your videos are great and really helpful. I have a doubt regarding, why are we not using the "Ratio column" in the simplex table. In our previous problems on normal maximization and minimization, the key row was selected by choosing the least positive value from it (Please correct me if it is least non negative i.e. if zero counts). Here we went for directly the largest value from the solution column, I'm a little lost here.
Same douht, may be it's a mistake ,to find ratio we have devide the solution with key column eliments,in this problem 1÷(-1)=-1, that's why mam select highest positive but it's a only positive value
when the solution value is divided with the corresponding key column value we need to consider least positive value of ratio column. but in order to save time, this is considered coz dividing will yield a lower solution.
Thanks a lot for such a nice explanation... I have a doubt regarding key row ... What should be selected highest positive or lowest positive for key row...
Aye...fear of the Lord. In Christ, are hidden all the treasures of wisdom and knowledge. (Colossians 2:3). Hallelujah Amen, say it again!!! I'm a Math Analytics & Operations Research Major at UC Davis, Ca. and found this encouraging. :)
Mining Prasad i have a doubt. Why aren't we using minimum positive value of the ratio column (solution column divided by the key row column) like in other simplex problems? Here ma'am used maximum positive value of the solution column instead.
You are saying that the problem is of minimization type only but in my book it is converted from minimize to maximize book is linear programming Krishna prakashan

Put example on maximization problem
Revised simplex method
why is it that in some place you choose most positive whereas in others you choose most negative
Please, I need maximisation problem with 3 and 4 variables ..thank you so much for taking out time to teach us.. God bless you abundantly Amen.
Mam 3 of Zj solution came from why
I just realised this video was published 6 years ago and its still THE BEST lecture for OR. Hats off to the effort ma'am 💯
Let How many years be pass by , your teaching videos will be helpful to over generations
Thanks Ma'am for the explanation.My professor told us to refer to this lecture as he cannot take so many online classes during the lockdown period.
If anyone has confusion try this!
Find ratios of each row(by dividing solution to key column value) and select least positive value from ratios and that particular row become key row
Then proceed further
pavan jahagirdar But that's when we're maximising.
@@vishchugh in minimization, u have to do the same boss
what if all the ratios found are negative?
@@taohidulhaider4893 Then you have issues

Thank you Ma’am 👍🏻🙌🏻 I learned all my Lpp problems from you
Youbdo wise,thanks much ive followed all of them from graphical,symplex and have helped me solve my lpp problems
Thanks for these tutorial.... I have passed my exam just because of you madam
damn, you're explaining is much better than my lecture
@@muhammadhusni3097 bro...ur not focusing in classes I guess🤭
nice explanation madam because i forgot all this methods when my teacher i said i recollected this methods by seeing this videos thanks once again helped in my degree examination very lot
thanks 😍😍 that's what I was looking for
you're the best teacher who explain lpp
Hello ma'am... thank you so much for your videos.. they are very helpful.. it helped me score 200/200 in my Board exams .. may God bless you
Thank you so much ma'am for existing in this world our college sir first study from you and then get told us to watch your videos the reason behind the sum is lengthy and is too bored to solve sum on board .
Once again thank you ma'am you're angel for our sir 🙏🙏
Thank you so much 😊All the best 👍
Respected mam, it is because of just your video I have completed all my operation research problem
I think I should pay the fees otherwise it will bad for not getting the value of her time although I know no money can be comlared to the value of your method and time
It has very tedious steps still you made me understand it easily! Thanks a lot!
Thank you ma'am. You are life saver!
Thank you ma'am....your tutorial videos are ausome...nice explanation....I am fully satisfied by watching these videos............😍😍
Tq madam...!
The way you r teaching is fabulous..🙏
You do very much easy problems, try doing tough one nd explain about the easy one.. You do vice versa! If possible tell us about 3 constrain which contains x1 x2 x3 x4..
Really mam, your explanation techniques is too good
THANKS A LOT MAM AND YOUR METHOD OF TEACHING IS TO GOOD
You are an amazing teacher ma'am . Glad I found you on time😊
simp alert!!
Mam, For = type constraint you have to add only Artificial variable not to subtract slack variable.
Ma'am you are our saviour 🙏🙏
Super madam chala baga chapparu thank so much
Very clear explanation .Thank you so much❤️
Mam you teaching style is awsome mam.
Nice Teaching 🙏🙏🙏
My all doubt are clear
Thanks 😂😂😂I got your channel...
I have my back log paper of this subject OR on 12 sept...
💝👌🌷🌹😘😍Hopefully I will clear this subject now...
All the best.
@@kauserwise tysm mam💝🌷🌹
Thank you for teaching me a subject I thought I could never understand or be interested in.😍
@kauser Wise
In greater than type we need to use surplus variable and artificial variable..*not slack variable mam...by the way your teaching is super mam
thank you mam for such an nice explanation . all the diubts of mine are solve .
U do very easy problems its easy to understand steps but if tough problems come cant do this type like 3 constraints
Please do tough problems and explain in easy way to understand
Thank you sooooooooooooooooooooooooooooooooooooooooooo much mam.......
The videos are lifeline for us....
Loved the way you teach ♥
Thank you so much man🙏🙏🙏,bahut achhe se explain kia hai mam aap ne..
You are the best mam❤️❤️❤️❤️ thank you😎
Good helpful tutorial. Appreciations :) but I have only 1 question that if it would have been a maximization problem that what would be the changes in the solution and conical form or model? Answer would be highly helpful and appreciable.
You are god sent ma'am 😄
I refering SD Sharma OR reference book. In that they converted problem from minimisation into maximisation LPP
Really u are the best mam
Good explanation......concept cleared.......
very well Explain .. All doubt is clear.. Thank you mam
2:49 . For = type problems we only need to add artificial variable!
Right.
Thank you mam.. And liked the quote from bible..
Superb video ma'am......thank you 👍
Madam it sooooo helpfulll.easy to understand .thank jesus
Praise the Lord
thanks mam u dont know how much ur video help me
Great mam! It helps a lot, thanks and god bless u
One of the best.
Very helpful!!! Thanks a lot!
Well explained , and such a gr8 knowledge you have . Thank u
There were more than 5 ads in the video... But thanks.. it helped me understanding then problem better..
Best video lecture i got here!

I have same doubt
Highest ratio value is considered in minimization problem, whereas lowest ratio value is considered in maximization problem

I have same doubt
@@rajsakhrekar1339 she used the least positive value for big m minimization too.
So calming to watch and learn...

Thanks a lot for such a nice explanation...
I have a doubt regarding key row ...
What should be selected highest positive or lowest positive for key row...
very nice explanation and thank you .
thank you mm it's very help full and it is in simple language....
I really understood the concepts. Thank you Ma'am.
Grateful!❤️
Very good lectures
Very nice explanation
Very useful...and thanks for ur video...
One of the best solutions

Mind blowing explain mam
Well teaching
Thanks mam, your explanation is very super mam,,,I understand so much,,,Any one ask me doubt
Mining Prasad i have a doubt. Why aren't we using minimum positive value of the ratio column (solution column divided by the key row column) like in other simplex problems? Here ma'am used maximum positive value of the solution column instead.
In the Solution part why didn't mam calculated the ratio via key row and then selected the minimum positive value out of those?
Thank you mam l'm really understood it
I wish you were all my lecturers😂
It's very helpful thank you so much mam.
Great job! Thank you very much mam...
It was very helpful , thank you
Thank you soo much for making this video

Mam, pls add more videos on two phase method and big m method..
I have a doubt. Why aren't we using minimum positive value of the ratio column (solution column divided by the key row column) like in other simplex problems? Here ma'am used maximum positive value of the solution column instead.
Thanks a lot maam
