    Thank you, Joshua! I had to watch your video for this, as my professor did not explain this well at all. I am new to using Excel for my class. I am watching all of your videos, and referring to my colleagues. You're a proficient professor. Also, for anchoring the variables, it's function + F4 on the newer PC's. Thank you, again !!!

    Really amazing explanation! Thank you! I have one question which is, do we have to add another constraint specifying x1, x2, x3 >= 0. I did not see that in the constraints box. Or it is covered when we ticked the below box for non-negativity? Thanks in advance

    • @joshemman
      @joshemman  Рік тому +1

      Yes, nonnegativity is applied when you check the non-negativity box.

    Hello, Joshua Im just wondering how you would adjust this process if there was an requirement for X3 = 0?

    • @joshemman
      @joshemman  11 місяців тому +1

      For X3 = 0, input "1" under the X3 variable, and "0" on the right side. Otherwise, you can omit X3 altogether. from the model.

      For 3x1 >= 50, enter 3 under x1 and 50 on RHS.
      For x2 >= 30, enter 1 under x2 and 30 on RHS.
      For x3

    • @joshemman
      @joshemman  7 місяців тому +1

      One issue might be with selecting the Min radio button in Solver instead of Max. You should also check that your formulas are correct.

    Why my LHS doesn’t equal RHS after solver.

      When LHS does not equal RHS, there is a slack or surplus.

    Why is excel even considered for linear programming? its so obsolete and garbage, you can solve the same problem in matlab with less effort. Excel is so dogshit and outdated
