Definitely the best tutorial in between those bunch of big m videos. Thank you so much.

[mariamilingou]

Fantastic tutorial!Thank you very much for your videos!I will hopefully pass my final exams thanks to you!

[pradeepgaur]

this will definately help me to clear my you ma'm

[ashiqahamed]

Thanks Great
Best In Youtube For BIG M method :)

I'm used to reading cursive, so i find your handwriting legible. But I think it may indeed help others who aren't accustomed to cursive if you were to write in capitals. Nice handwriting though.
Great videos too, it was a clear explanation

Very good job! Best tutorial of big M on youtube

[emptyclud]

Thanks for the wonderful tutorials. Best ones I've used to learn.

Thanks professor, please upload some videos about sensitivity and shadow price,
kheylii khub boodm mamnun, goftam farsi am tashakor karde basham ;)

[cansengul]

you are really good, thank you professor

[luckymact]

thank you ma'am, you are awesome.

Mirzaei, this session was good and very useful. Did you posted any video relating Gomory's Cutting plane method and Branch & Bound method problems. Kindly give the link. Thanks

[MerveNoyan]

You helped a lot but I didn't understand how and why you switched from s2 to e4

[waraymohamedamine]

Thank you for the videos, they are great. I have two questions :
Do we always add -M ? or we add -M for maximization problem and M for minimization problem ?
Same question for the artificial variable (a) ?

[harun]

Thank you professor but i have one question. What we supposed to do when there is more than one > or = sign ? 

[mariamilingou]

So if I get it right..if the initial problem was a minimization problem then we would have to add e's to the <= conditions and subtract a's and then to the initial equation we first add +Ma and after it all we would have Z-3x1-4x2-Ma=0 ?

[LuKaSoo]

What if all z row elements are positive but you still have M at the final value of z??

[camilot]

so if the artificial variable (either a4 or 4e) are another number other than 0, does that mean that there is no optimal solution, because there is no feasible region?

[loganism]

Hey Prof
So do we use artificial variables in Simplex too in case we have a perfect equality constraint?
