This is pure GOLD, the best LP video series ever. Thank you so much!!

[maddoscientist]

Best LP videos I've found on youtube. Thank you so much!

[kowyo]

I love this!!! because I follow your method in Intro to Simplex Method | Solve LP | Simplex Tableau and the optimal solution develops in a oppsite direction and I am so overwhelmed. This video surely helps!

Sir I think the following topics are left
1. 2 phase method in LPP
2. Duality in LPP
3. Dual Simplex Method
4. Assignment

Again hat's off to your dedication for making such amazing simple but elaborative videos....☺☺☺☺

[KanalmitNivea]

Extremly well done. Clearly explained, great animations - thank you!

[geniusharma]

Thank you so much !!!! It was so effective and simple to learn which I couldn't find on any other youtube channel

[BenchMeister]

love these vids. usefull for business engineering or business economics

[gbalakrishnareddy]

Thank you a lot for explaining complicated things in a short time

[Raghav-wj]

Hope you continue making such wonderful lessons sir!

I think there is a big typo on 6:06 where the slack variable has a cB of 6!

[Apersonll]

when should we introduce an artificial variable a to test for infeasibility when constructing the tableu form?

[danqiuWei]

can you make a video about duality linear

[sourabhborkar]

You missed one important point in Degeneracy is the possibility of "cycling".
