    I've spent today watching so many of your videos and they've helped me more than my professor ever had this semester. I finally understand it! Thank you for making these videos because they actually make me want to learn it. Keep up the good work!

    Dear Chetna, look carefully I've crossed those two zeros by L1 and L2 lines. I've drawn lines in the order row2(L1 with 2 zeros),row3(L2 with 2 zeros),row4(L3 with 2 zeros) and column1(L4 with 1 zero). But you could draw lines as column1(L1 with 2 zeros),column2(L2 with 2 zeros),column3(L3 with 2 zeros) and column4(L4 with 1 zero). The answer will be the same. Order of drawing lines doesn't matter as long as you follow the rules.

    Hi Sujoy,
    Can you please explain how to get to know weather the matrix in the problem is for minimisation or maximisation?
    Waiting for your revert.. :)

    @sashankgokavarapu4215 8 ปีที่แล้ว

    What if uncovered elements have zero after the drawing of lines for first time
    As u said we have to choose smallest in uncovered if there is a zero it makes no sense in adding and subtracting that smllest number(0)

    • @abhishekkarn8918
      @abhishekkarn8918 8 ปีที่แล้ว

      You have to cover all the zeroes...so there will be no zeroes left in the uncovered elements....:)
      Hope it helped...:)

  • @b89purvakhetan36
    @b89purvakhetan36 9 ปีที่แล้ว

    plz tell me..
    how do we get to know the qs is minimization type problem or maximization??
    Because..
    in minimization type.. we subtract lowest no. from each element of each row. (step 1)
    whereas in maximization - we first subtract each element from the overall aximum number in mtrix ( step 1)

    • @sujoy70

      Sukhjinder Singh You mean what to do if intersection element is zero,right? Nothing will differ in that case. We'll add 'smallest uncovered element' with that intersection element; as we do with any other intersection element which is not zero. Hope it was helpful.
