thank you

[ihatethisshitlemebe]

Will you marry me?

[GlowMagik]

Thank you very much :)

[soccerhollic96]

is there any time that we are going to have remaining slag? if we do what do we do with it? thank you for all your help =]

[keeponrockin87]

I LOVE YOU! =) Thanks so much! 

[AdighaSreqwash]

:'D thank you very much god bless you :)

[knanx]

thanks thanks thanks...... bilion times, was very helpful for my tomorrow exam:)

[SlappieRemon]

Thank you! It was very logical and easy to follow. Without you i did not understand the course! Greets from the Netherlands

[shah7966]

thanks a lot brother

[HappyTroll100]

What about minimising? Do you do the same only look for positive numbers on the bottom?

[dapmp91]

@HappyTroll100 i think for minimizing you simply maximize the profit function, except you add negative signs to all the terms in the profit function

[ars02]

thanks_mr_patrick!!

[cholliscook]

Absolute GPA Saver!!!!!!!!!!!!!!!!!!!!

[HappyTroll100]

YOU SIR ARE A LEGEND!!!!! THANK YOU FOR THIS GREAT EXPLANATION

[fuzzballer15]

That's great, thanks. I understood it when i first studied it but now couldn't make out anything from my notes so this really helped.

[BigMarvelFan747]

Thanks for the tutorial man. I could understand it when u explained it like that. My professor however, I'm clueless. Thanks again.

[Deceptibotimus]

Best tutorial ever. Like... Wow, i actually get this now...

AWESOME TEACHER.

[nadjafink]

Thank you very much! I might have a chance to not fail my math exam this time. So thanks a lot from Berlin/Germany!

[illysuar]

what if after having completed all the pivot operations to get all the negatives out of the bottom I am left with a negative on the right hand column...Would the solution be multiply the row with the neg number by -1? Cause I tried that and still didn't work.

[primmanet]

great video!

[svon3512]

just wondering can you only ever have 2 variables that are not set to 0?

[runzombies]

This was extremely lucid and helpful. Thank you! I'm definitely subbing and coming here with math issues!

[canadastc]

thanks a lot for ur video, it makes lots of sense and saved me lots of time.

[Braru316]

Thank you for your good lectures, it hasn't been long since I've found your videos but I always try to look for them when I have any difficulties because you explain so well.. keep it up :)

[jianh1989]

In 0:59, why are x2, s1 and s2 are set equal to zero?

[carnot23carnot]

great tutorial ! very simle(x) and clear.



[RickyRixxx]

Wow, you totally cleared my doubts. thanks so much.

[christiancheer]

great video! helped me a lot, thanks!

[toxton1]

awesome . i it'd be better if you explain how to know when a problem has no solution or infinites solutions

[ashishicici]

Superb.....was'nt getting clear abt how to do row operation . Gr8 help ...



[lujangus]

Great job. I had a class about simplex method at school but the professor would explain over a power point presentation. But you get lost if you only see fixed numbers. I think they way you did it is better. You made the simplex method, very simplex.

[wreklibog]

Thanks for posting this. It was definitely helpful and filled in some information my prof. glazed over.

[i12win]

Way to post a very informative yet easy to understand series of videos! This way great for the last hour of cram time before my Operational Research exam!

[MsVikas1991]

u are awesome sir the tutorial was gr8 to be understood

[patrickJMT]

@MsVikas1991 thanks, i hope it helps.

this stuff is just soooo loooooooooooong.

(that is what she said)

[jfarrau]

gracias pile x la wea, kche kleta

[death0intj]

i've been looking around for explanation of how simplex algorithm works, but all i find is description of mechanics, is there any source that explains mathematical/geometrical background behind this algorithm?

[patrickJMT]

@death0intj pick up any textbook with it, they will discuss it

[wladston]

Thanks for the videos!

What I could not figure out is how you derived the solution from the Matrix! How could you derive that the solution has x_1 = 200, x_2=0 and x_3 = 300 ? What is the relation between the matrix and this ?

[starsdestiny]

@wladston Me too... I wasn't taught the "swap out" to the LHS. 

[fuu1989]

thank you so much !!

i understood how to operate simplex method now

[prolarka]

Id like to see the explanation on why is this workin?

[NinjaXSong]

Hey, could you make videos of some problem-solving techniques? For example, AIME style-problems, IMO problems, stuff of that sort? It's because once you learn this stuff, you still might get struggles, but the solution will always be clear. The examples I just mentioned are never straight-forward and take alot of tries before finding a solution.

[Freestylr88]

I definitely learned the Simplex Method in my programming class (Advance Topics in Computer Engineering) this past summer!! Its pretty kool. Though it could take a while its definitely rewarding. We also used this program called AMPL which pretty much gave you the answer or a reasonable answer. 

[zalida100]

I think I could follow the mechanics of the method ok.

It looks like there are only 2 places on the left side of the table for component types (x1 and x3 in this case)

It's not clear what it'd look like if the solution would involve 3 types of components.

I've obviously missed something. Guess I'll have to watch the video 2 or 3 times to figure it out.

Great fun - Thanks very much

[RobertMStFleur]

Your explanation is clear and simple, thanks for the add.
