  1. im very happy sir , bcoz i didt get even single point in d class room. bt in hear i learned lot of thinks . thank you very mach sir

  2. Thanks alot for the lecture…it really helped me alot….. u are awesome…. 🙂 🙂 🙂

  3. Thank you so much Srinivasan sir .. your lectures helped me to get 1st Division in my MBA exams … Awesome Lectures and easy to understand .. Thanks a lot.

  4. Thank you so much for clear explanation. I did not know the basics of simplex method.

  5. Thank you sir for explaining things so clearly which otherwise would have been difficult for me to understand on my own. Best teacher of mathematics ever!

  6. Where do i find the complete course ? I'm doing a research on the subject trying to study how the method reacts to disturbs and this course will be of great help. Thank You! 

  7. Wah wah wah kya baat!!! I would love to watch this video again and again..great prof,thank you (Y)

  8. Sir… it was superb!! Similarly explain Integer programming problem.. please…

  9. Thank you Sir..I tried studying simplex method through various books & sites..but none of them was as convincing as your method of explanation is. Only I have a slight confusion, is it necessary that every time we will get identity matrix of 0,1..supposing if we have other elements like 2,3 or other comb…then , will the same methodology  be followed? 

  10. sir, In the second iteration, the basic feasible solution should be, x3=1, x1=4, z=24 and not X3=5. as you've said. 🙂

  11. Thank you sir, I was wondering if we could use the same method for a minimization problem?

  12. Thank you sir. You so very clearly explained why the steps of the tableau method work by showing us the algebraic method first. It makes so much more sense to me now. I wish all other teachers would approach introducing the simplex method this way.

  13. very clear method for teaching simplex   and this video one of the best lectures i have seen before.

  14. I completely understood Simplex in just under an hour, excellent Professor! Would love to see many more of his lectures.

  15. Thank you sir, this was really helpful. You were taught in a very difficult method by Dr. M P Gupta, but your lesson is very easy.

  16. it was very helpful fpr me,before few hr of my exam..thank you sir

  17. great professor and great topic. I am a graduate student at Loyola University Chicago; I am doing a revision of basic OR topics. These videos are so helpful; thank you so much Prof.G.Srinivasan

  18. In some places I have read that we terminate the algorithm when all Cj-Zj values are either zero or POSITIVE, unlike here where they had to be zero or NEGATIVE. I am confused. When do we apply which condition?

  19. When i get a negative in the last volume what to i do? Do i compare it with the rest of the values as normally to see if it is the lowest and use it as a pivot row or do i no longer take it into account, just how i would do if there was a zero in the pivot column?

  20. i am watching all your lectures from starting sir and taking notes from it. i have learned much more easily and attractively how to tackle with simplex problem . this is my 4th day of 4th lecture . thank you nptelhrd for uploading the lectures to allow students to learn OR by Prof. G. SRINIVASAN . and have a taste of IIT learning .Thank you very much sir …

  21. If all theta values are same, then which row to choose as pivot row ? Any help much appreciated. 🙂 .

  22. does the theta column only include non negative numbers, or only positive numbers???

  23. why cj-zj value should be less than or equal to zero in maximization case and vice versa??

  24. Thank you so much Professor. Now I have clearly understood how the simplex method works by relating it to the algebraic and graphical method. Earlier I just knew the steps, but now I have clearly understood how it works.. Thanks a lot!!

  25. awesome…. The human being understands something when he is explained why … and you do it very well … thank you !!!!

  26. Thank you so much Professor Srinivasan for sharing this knowledge.
    May the equations to attain happiness in your life (although most likely non-linear), be forever optimized.

  27. Thank you so much Professor! The lecture is awesome & i learn SIMPLEX just because of you. Clear & to the point explanation.

  28. I can clearly guess that there is a very very close link between the simplex method and Gauss-Jordan elimination(linear algebra). I solved the algebraic method by finding the null space of the matrix(corresponding homogeneous one) and adding a particular soln: Xf = Xnull + Xpart.
    The simplex method also appears similar. It also transforms the matrix as [I F] form and then tries the find the sol. This is what I have observed! (Actually I have been following Prof. Gilbert Strang and he always emphasizes the relation between the various vector spaces and this soln appears very similar.) It would be very helpful if someone can tell me the missing link: i.e how the basis and independent variable change every step and how it actually leads us to the soln, and also why is it try(by linear algebra). Thank you!

  29. E-Teaching should be for last minute preparation, so much lengthy if u make short videos for short and last minute. It was just waste of time exploring around.
