Matrix Form of the Simplex Method

[@Dennaton]

Greatest explanation ever, our professors are generally teaching on matrices unlike I think any other university in the world. (From Bilkent University with love)

[@skittles6486]

I am a Ph.D Scholar, and I did a course before on this, but never understood the concepts so clearly. This video not only helps us to learn Simplex, but this video also helped me how to teach simplex to someone. Generally people start with matrix method and then goes to tabular method, which is a wrong way to teach. Thanks a ton for this beautiful series of videos on Simplex. Millions of blessings from my side for this.

Thank you very much

[@aishikroychaudhury8656]

Amazing. I couldn't find such explanation anywhere else

[@yeppeosseo6922]

THANK YOU SIR YOU ARE MY LIFE SAVER!!!!!!!

[@M1ntAll]

The explanation of the algorithm is itself brilliant, but can you suggest some sources to get the intuition behind these operations with matrices?

[@lee-su-rin]

You are Wonderful! Thanks for saving me...!!

[@vrf9694]

your videos are very useful but without music they could be perfect... it's distracting and unnecessary

[@goutamkundu6392]

Excellent tutorial....Amazing....Many thanks

[@zeca7796]

Thank you very much, this has been super helpful!

[@fazaldeenpathan108]

Amazing thanks Respected sir.❤️

I realy like these movies but please, do something with this piano malody constantly repeating in the background. Listening to the same piano patern for 15 minutes can drive people crazy ;)

[@GOALPROJECT]

Thank you for your comment... we will consider your opinion in future videos... Thank you again...

Hello, I have one quick question. For the 3rd constraint at 1:49 of the video. Why is your artificial variable labeled A3 instead of A1, since is it the first artificial variable being introduced? I would have thought that the artificial variable would be A1 since it is your first one. Hope this made sense. Thanks

[@GOALPROJECT]

Usually, the subindex of the slack variables and the artificial variables are given based on the row or constraint where they appear

[@galatians6939]

@@GOALPROJECT ohh that makes sense. Thank you!!

[@nivethashivakumar8329]

Thanks for clear explanation. Can you please confirm whether the method of solving Matrix form of LPP as in the above video and the revised simplex method are different?

[@huh7455]

Could you explain about Simulation problems such as Simulation approach - uniform distribution

[@duyvo5315]

Thank you very much!!!

[@dariodangella5040]

what is the purpose of adding the artificial variable A3?

[@lee-su-rin]

I think he is using Big M method.

[@dogukanyucel207]

if we have excess variables ​​will they be included in B or only s + a ?

[@GOALPROJECT]

Only s + A... :)

[@minash7157]

Thank you very much! Can I ask why the order of columns matter?

[@palashchandrakar1112]

amazing thanks for the video

[@ameypanse3558]

While initially selecting the column for basis matrix (matrix B) does it has to be an identity matrix?

[@JRay2113]

Can you do sensitivity analysis next?

[@GOALPROJECT]

there is a video "introduction to sensitivity analysis"... kzbin.info/www/bejne/qKDHeoulr66Xibs

[@olivier306]

Thank you!!!!!!!!!!!!!!!

[@filiphejnic4286]

How it is secure that right hand side is always positive when you take basis columns always from original matrix A ?

[@johnantoniou8739]

is the procedure the same for more variables ( x1, x2, x3 ) ?

[@GOALPROJECT]

The procedure is the same for any number of variables...

[@johnantoniou8739]

@@GOALPROJECT thank you so much

[@meriem9992]

excellent ..but how did we know that -2M-4 is the smallest ??

[@GOALPROJECT]

You should think that M is a large number, for example, 1000. Then -2M-4 = -2004. If you substitute the other M's for 1000, then -2004 will be the least of all.

[@meriem9992]

@@GOALPROJECT merciii

[@pranavbansal6531]

Because M is usually assumed to be Infinity. But because we cannot input Infinity in Computer , therefor we take M as a Large number such as 1000 or 9999 etc.

[@atkn3428]

why is the b prime= (14,12,6) minute=6:48

[@atkn3428]

okay now I got it, thank u so much

[@issam301]

good but how to obtained B-1

[@GOALPROJECT]

Using Excel... :)
