    3:55 I think you shouldn't cross that 2nd row as when we see single 0 row-wise we strike out only the respective column. Moreover, ultimately your no. of lines is 5≠4.

    Since the minimum value is 9 you should add nine in both 3:07

    1:57 why added 5 at intersection point?

    • @GauravJM-s6c
      @GauravJM-s6c 4 роки тому +1

      That is a part of the process in Hungarian method..... U will have to add min value at all points of intersection to get an optimal solution...

    does this procedure is same for balancing the tranportation problems?

    • @qntsformulation2538
      @qntsformulation2538  5 років тому +1

      in order to balance an assignment matrix, the number of rows should be equal to the number of columns.
      But in order to be balanced a transportation matrix, the total number of demand should be equal to total supply...

    You had 5 lines at end of equation that is “Not Optimal”

  • @warrentamayo2563
    @warrentamayo2563 5 років тому

    is this is a minimization problem? from our lecture we have a column reducer but from your method you did not. So which one shoud I use?

    • @qntsformulation2538
      @qntsformulation2538  5 років тому +5

      answer to your first question is yes, it is a minimization matrix.
      And to the 2nd, we need to perform column as well as row reduction all the time. But in this particular question, column reduction is not needed as each column already has a 0 element. Because if you go for column reduction, zero will be subtracted from each element of each column and that will create no difference...

    • @qntsformulation2538
      @qntsformulation2538  4 роки тому

      In that matrix, 5 is the minimum uncovered element, and we are subtracting 5 from all other bigger elements, thus we get 1, 5, 9...
      We are actually applying the Hungarian method, which I explained earlier in this video:

      which zero?
      ask properly...
      And this section is only about solving the unbalanced problem. If you want to learn all the rules in Hungarian method, please watch part 2 of the series...
