I learnt more in this 5 min video on 1.5 speed than the entire cohort of my education trying to teach me.. thanks Joshua

[@jeancamillepingkian6456]

True that

[@roderman93]

I am almost positive i'll do 20% better on my exam tomorrow purely because of this video

[@walacexx]

Have you succeed ? haha

This literally covers 9 lectures over the first 3 weeks of my 2nd year LP subject. It does it so much clearer too - Thank you :)

[@bjkocean]

The clearest explanation about slack variables. Thanks !

[@FPrimeHD1618]

You are one of the easiest people to understand and follow. Your LP series has helped me out tremendously. Thanks!

[@MilenaCasey]

I can't thank you enough this is exactly what I needed!! You've explained it better than anywhere else I checked

[@HelghastSon]

One of the most helpful videos on LP i've seen. Your voice is nothing short of soothing and enjoyable to listen to. Thanks!

[@bodgukalism3]

7 year old video and you absolutely saved me from nightmares about this stuff! I appreciate you more than words can describe, have a blessed day!!

[@andrewmoore4549]

I have taken two linear programming classes, watched countless videos, and read only knows how many lecture notes; your video is the first to clearly define and help me. Thank you so much!

[@NoemiT210]

I agree

[@nobby30]

You have an amazing ability to impart knowledge in bite sized, easy to comprehend, dare I say it enjoyable pieces!! Banging my head reading my course text til I found you! thanks so much!

[@gosiahoot3493]

Very clearly and concisely explained! Excellent review for my analytics class. And if you ever teach on diplomacy, I'm sure we will have world peace in a week. Everybody should subscribe to you just to support you as a teacher, even if they never watch again.

[@pxosted]

it took my professor a week to explain what you have in a 5 minute video. god bless

[@zhongcharles7852]

The only commend I would make is: brilliant. Clear and explanatory, extremely helpful even without sound. Thank you so much.

My textbook introduced slack variables but didn't explain why (what they meant). THANK YOU! Makes total sense now.

[@missghani8646]

thank you for the clear explanation and must say for the really FIRST TIME I have slowed down the speed of a video, usually I speed up the video at least at 1.5, but thank you for the quick and clear explanation.

Can we say that the slack values are the equivalent of the lambdas in the Lagrange method?

[@wiperswinger]

I appreciate that.

[@yalakaturi.saidivya9158]

In the 2nd example given condition is min, that converts in max. Mutliply with -1.

[@rushilshah5477]

This is a really good video, thanks! Does the slack affect the graph drawn?

[@joshemman]

No. Slack/surplus do not affect the solution.

[@gcagpata3]

how about when you have a multiple optimal solution question?? how do you calculate if its binding or non-binding?
