I could cry from happiness, I genuinely thought it was imoossible to understand, but your video made me a believer for sure😭 Thank you for this clear explanation, you just saved my life fr

[@sepalpk]

I had watched 4 videos of 20 min but didn't understand after i saw your video i am 101% clear. Thank you professor

[@frontendprotogy6749]

honestly, i have been reading through notes given by lector couldnt figure out a thing, now after i watched your video go back to reading notes and now i know what lecturer ment, thanks you man, life saving...

[@joshemman]

Glad to know it helped.
Thanks for dropping a note.

[@balooojeffersong4234]

I love you right now lol. This concept is actually pretty simple but no one was making it so ez to understand like you are! Thank you sir!

[@joelr9924]

I have been looking all over for an explanation to a similar problem. Thank you so much for videos! Keep it up

[@muhammadammar9605]

Seriously.. That was the best video on CZcams related to simplex method..👏👏 simple and easy to understand.. Keep up the good work, brother.

[@sarahgh8756]

100% clear. you explained simplex method in the best way possible. step-by-step including necessary details. Awesome tutorial. Thank you.

[@DarshanGad]

Finally Finally understood this tableau method!! Feeling confident to pass the exam this time at Chalmers! Thank you! Please consider being a teacher if you aren't one already!

[@1biglostsoul]

May Gad be with you ❤️‍🩹

[@ieatnoodls]

clean and concise thanks 👌good for going through step by step along (note: this is for maximization, minimization is a little bit different)
For Minimization you need to change the following:
- select column with _most negative_ cj - zj number instead (first in case of equals)
- still select row with the smallest positive ratio value
- optimal solution is found once all cj - zj numbers are positive when minimizing instead of negative. (greater or equal to zero)
Everything else stays the same. also note that the cj don't change throughout the iteration so no need to check for them :)

[@assasinsquirtle5889]

It is actually hard if not impossible to find a spanish spoken video this clear and using the simplex tableau, thanks a lot !

[@joshemman]

Glad you found it helpful. Thanks for dropping a note.

[@evangelynegideon6436]

Thank you so much. I now finally understand this. You have made it so clear and simple with the steps you provided at the end. 🤝🏽

[@labronkatz5942]

Bro you are explaining well but you are too fast😭

CZcams recently added a setting to change the speed of a video. It's under the gear.

[@user-kc4lq4ex9j]

The video its good and understanding, i thought it was incredible hard but its to simple to understand. It is just the matter of connecting dots. Thanks Bro..

[@alfianrsa]

Been having trouble with it until I saw this video, this is the explanation I needed. Thank you

[@aniketsharma1719]

Thank you joshua for clearing the topic. My teachers are capable to teach the subject can't control the class so was having trouble in understanding the concept thanks once again, it is a request that anyone who is reading this comment go through this video 2-3 times for more and more clarity 🙌

[@joshemman]

Thanks for your note and recommendation, Aniket.

[@ol352]

This is the most educative video on simplex method, all the rationale is explained, making the process intuitive. Thank you.

[@bismillahyusufu5121]

Thank you so much. This video is so good. It has helped me remember all the steps I had forgotten in my undergraduate course. I pray to Allah to bless you and guide you.

Will always the slack variables become non-basic for any simplex compatible problem once the cj - zj row

[@cryptsampro]

Thanks for this 🔥
What of there are 3 or more constraints?..

[@antoinep5475]

Hey, what if my column s2 has cj-zj = 0.625, so is positive, the actual solution is good but not optimal, so I need to do another iteration by replacing my x1 in the basis my s2 ?

[@adione6269]

You are the best!!!
