    Thanks a million Mr. Srinivasan. I passed my exams with good scores thanks to your lectures. Greetings from Turkey!

    I got to admit, I envied Indians because they fill in lots of jobs and professions that others ever crave to have; but now, I understand that all the lessons, lectures, and important notes & tips on TH-cam comes from tutors, especially Professor Srinivasan, whom have given me the needed enlightenment. Without them all, I would never know where I would stand; can't imagine my life without their educational powers which keep feeding our minds with magnificent knowledge each time.
    Thank you Professor for giving me hope, especially in this class.

    Respected Shrinivasan Sir,
    I am a post-graduate student studying in USA.
    I have exams tomorrow and the books I am using here are really a mess, and really confusing.
    I thought I had taken a wrong decision, opting for the optimization course.
    Its just an amount of one hour virtually spent with you which has made me realise that indeed I have taken a really easy and interesting subject.
    You are really a great teacher Sir. Thanks a lot.

    I got stuck when you were explaining the thetas in MODI method.
    But ur presentations are SOOO good, one pause, is ALL it took for me to understand it again.
    You're one heck of a prof sir!
    Cause with a book, once I'm stuck, I'm stuck, done, and defeated.
    But u sir, have my respect. Thank you!

    Very nice video: best online teaching videos I've seen and great preparation for my exam :) (even though couple of minor mistakes e.g. the starting feasible solution was obtained from the minimum cost method, not VAM and at 16:47, 8-6+7-6=3 not 2) but these don't matter the quality of teaching at all! Thank you.

    Dear Dr. Srinivas,
    calculation error
    15:11 - cost calculation - it is (20 times 6) -120 not 100 so the cost would be 940 instead of 920

    • @raghavgoyal3324
      @raghavgoyal3324 8 ปีที่แล้ว

      he did one more error ... as he calculated 100+80=200. but answer is 920.

    it was obtained through VAM. by VAM there were two solutions due to arbitrary selection of blocks. 920 and 960. and 960 was also given by minimum cost method :P

  • @shivanmohyaddin
    @shivanmohyaddin 10 ปีที่แล้ว

    Sir, in 29:35 , the formula you used to allocate the NBV locations
    you wrote like this Cij - ( Ui + Vj ) = Xij ,
    But my book says, the formula for allocation NBV locations is like this Ui + Vj - Cij = Xij
    For example:
    If; U1 =0 , V3 = 6 , C13= 8 , then applying your formula it gives,8 - ( 0+6) = 2
    but in book it gives, 0 + 6 - 8 = -2
    so we have a difference . your formula gives +2 , while book gives - 2 , which formula is correct ? Yours or the book ? also my book says if all new numbers you got in the empty squares were Negatives then you found the optimal solution , everything is opposite , you say if the numbers are alll positive then its optimal while book says opoosite ....
    Please help me, this is a serious issue , i don't know which formula to use now, yours or the book :( .. this is a really serious issue , either the book is wrong or your wrong,or maybe both ways are correct but i know im not wrong , you can check the book by your self

    • @vivekr5321
      @vivekr5321 10 ปีที่แล้ว +1

      It doesn't matter. It's one and the same thing. Only difference is, when you take the net cost for unoccupied cells using the formula in the video, you search for a -ve value, which means, the result is neither optimal nor unique.
      Using the formula in your book, you search for a +ve value, which means, the result is neither optimal nor unique.
