Now i will be able to get 10 marks in exam for this problem. GREAT TEACHING. LOVE FROM NEPAL

[@riyabisht7259]

Thank you so much sir, Mene mushkil se 2-3 ghante pde exm ke pehle din wo b sb aapki videos se jitne topic the aur aaj mera exam kaafi bdia gya, sb questions aaye mujhe jitne video se seekhe the, saare attempt kiye mene. 🙃

Sir i got both the concepts 1 and 2, but there is big confusion i have is.....when to use concept-1 and when concept-2 Plz tell this and reply as early as possible so that i can go ahead in syllabus

[@SandeepKumarGour]

You can use either concept-1 or concept-2, there is no any choosing criteria. Thax for watching☺️

[@ketansharma6206]

@@SandeepKumarGour but sir, I think answer will be different??

[@SandeepKumarGour]

Only standard form will be different. optimal answer will be same.

@@SandeepKumarGour thank you 🙏 sir

[@SandeepKumarGour]

Welcome..

[@yogitamalviya7471]

Sir really, you teach vry well!!

[@amitrawat8075]

First of all thanks for this lecture series🙏 Hats off man 💓 I think there was no need to classify them as concept 1,2 it just makes things more complex.. as In Operational Research every problem has a minimisation solution too but as it's easy and simple to focus on just Maximisation ones by converting min to max so we don't really use min solutions but it's used in Duality as we have to further solve it using simplex method so min primal to max dual makes sense Even in concept2 the solution to max problem was same as it was in concept1

[@SandeepKumarGour]

Thank you so much for your support and valuable words..☺

[@daddysdaughter7221]

Why we use concept 2?

Sir primal se dual me convert karne ke liye minimisation Ko maximization main kab change karte hain

[@MohdAli-bw1np]

thank you so much sir, lecture was very helpful

[@ramanbhardwaj6909]

to good sir❤️

[@sandeepjaiswal7505]

Nice explanation sir thanks for help us, sir if concept 1 and two get both give same dual form? ?please answer

[@mathsbyrohitgupta5665]

sir minimization primal ko dual primal me change karte hai to maximization karne k liye - sign se multiply karke change karte kya ya aise hi kewal likh dete hai ....please sir reply

[@SandeepKumarGour]

Primal lpp ko standard primal me convert krte time ydi object function ko change krna ho tb -1 se multiply kiya jata h

[@sourabhgupta2390]

Tq sir

[@SandeepKumarGour]

welcome..keep watching my videos

[@anukhandelwal5673]

Thank you Sandeep for such great video. I have one basic doubt. Why are we doing this? What do we get by converting from primal to dual if we can simply solve the primal?

[@SandeepKumarGour]

sometimes given lpp can't be solved , therefore we have to convert it into its dual.

[@muhammadirfanjoyia3244]

Sir. Why we convert fn mininimize to maximizie for solving it by simplex method?

[@rivali9660]

Sir Primal have max

[@samiulalam100]

Sir, in the example 1, I've two doubts. After converting into dual, won't there be two variables finally instead of three variables? And won't be one of the variables unrestricted in sign?

[@sonugagankarn]

Excellent brother.... Appreciate..

[@SandeepKumarGour]

Thank you so much☺️

[@anjalijaiswal9089]

Find dual of below LLP ( only issue is what we should do when x2=3 x1-x2=0 , x2

[@gauravpathak7017]

Thanks for the great technique sir !!

[@beingyourself4379]

If in the dual solution all max value appears in negative sign....can I write it on min value with less or equal sign........and can I use same on subject constraints?

[@gauravpathak7017]

If x3 unrestricted ke jgh x3

Which lecture is fundametal theorem of duality

[@mathsbysanjay8558]

Sir ye dono form me se kisi se bhi exam mein kare toh galat toh nahi hoga na ya fir particular bola jayega concept 1 se karo ya concept 2 se

aap kisi b ek concept ko apply kr skte h.

[@beingyourself4379]

Sir I just did your solved problem in concept 1....but my ans is not matching with yours,my ans is on min.....and your is on max value and the constraints parts also not matching with yours,..... my ans are different apart your answer.....what should I do now?

[@SandeepKumarGour]

here we have two concept for converting primal to dual , pls send your solution on my email id , I' ll check. [e-mail]
