Im in a 3 hour lecture class and my professor attempted to lecture linear programming in 3 hours.. and I learned how to do it in about 15 minutes with this video...
This was so helpful! It's funny how I understand better watching video tutorials rather than real live lecturers teaching in front of me lol. Very helpful indeed!
I opened the chapter in the book to do an assignment with a frown, 20mins later I was searching for tutorials on youtube and 1st one I clicked on was this cos I saw an old man in the avatar..... 15mins later I'm smiling and recommending this video to classmates.
@@Brewskidudes I was teasing. That saying is from a favorite song of mine by Delbert McClinton. Glad you found the tutorial useful. I have hundreds of tutorials on Algebra and Calculus, so check them out if you need help on other topics too. Good luck!
Great example of LP. Clarified many questions I had. I appreciate you not skipping over the "simple" stuff and working all aspects of the word problem.
Dear Randy Thomas; In your example of the farming profit optimization you are mixing apples and oranges. The first constrain plots the total land available in [acres]. The second constrain plots [hrs/year] spent on each product ON THE SAME axises. Therefore the intercept of both is completely arbitrary; it may not exist. The units on both axises should be consistent in order to obtain meaningful results.
Thank you for the helpful video. I'll note that for programming applications we simply use a matrix representation. Then use gaussian elimination to solve (unless there is a more efficient method), then use the objective function to find the optimum (with code of course). So, same thing, just done with matrices.
Dear Randy, Thanks a lot. I am learning this as part of my MBA program. My teacher teaches really well. However, I am bit weak in grasping concepts when it comes to math. This video was really helpful. Since the basics are now clear to me, I feel more confident. Thanks again! God Bless!
calming voice and a perfect presentation and example in order to explain linear programming, and you made it look so simple because it is the way you taught it! I was having troubles before and now I understand it, thank you so much!!
Thank you! We were asked to do a project which involved LP although we never learnt it! This video solved half of the problems I faced! THANK YOU so much!
This was so helpful! I have been working on this in class for days and have not understood it but after this video I totally get it and I'm confident for my test. Thank you so much!
its good,but i have question,the question is .The uses wood and labor to produce tables and chairs.Recall that unit profit for tables is $6,and unit profit for chairs is $8.There are 300 board feet of wood available,and 110 hours of labor available.It takes 30 board feet and 5 hours to make a table ,and 20 board feet and 10 hours to make a chair.Then a.Formulate linear programing problem. b.Construct the graph and plot constraint lines. c.identify the feasible region. d.determine the optimal solution by algebraically calculating coordinates of the most attractive corner.
Jump straight to 4:55 to get to the easy example. This is a common example used elsewhere, but explained most clearly here I felt. For my simple brain, I got completely lost in the "theoretical" preceding, but I understood the example. Ps: Thanks.
The video has made things quite clear in a simplified way. Thank you. I just have one question: why did you multiply the equation x +y = 240 by a negative and can we do that with every equation we formulate in linear programming?
good morning M Randy, I would like to know where u use Lpsolve 5.5.2.0 for linear programming , if yes do you have a video for that . i have to use it ! thanks
very nice lecture. what software are you using to draw? I need to submit my homework with a digram ike the feasible region. thank you in advance for your help.
Hi, i've a question: make a linear model in linear programming by disributing a 8 queens in chess where each queen doesn't contact with eachother in distance
Theorems were invented in 1939 proving that for optimization of linear systems always occur at the vertices of the feasible region which is bounded by a set a linear inequalities. Google "linear programming" if you want to understand history of its discovery or its theoretical underpinnings. In this tutorial I am just showing how to apply the concept.
Please, I would like to get the answer to these Questions: a) Repi Soap Company wishes to make a new detergent from two of its current soaps: Soap A and Soap B. The new mixture must weight no more than 4 pounds and is to contain at least 6 ounces of cleaning ingredient D. Each pound of soap A costs $4 and contains 3 ounces of D, whereas each pound of B costs $1 and contains 1 ounce of D. How many pounds of each soap should be used in the mixture in order to meet the above requirements at a minimum cost? What is the minimum cost? b) Repeat the above problem, if in addition, the amount of Soap B cannot exceed the amount of Soap A by more than 1 pound.
For capturing the video I use Camtasia Studio. It is not cheap. The same company has another program call Snagit which is cheaper with less video editing features and a free program called Jing that I started with for my first videos. For the content on the screen, in this tutorial I used a free download program called Jarnal. I also frequently using Smart Notebook which I use in the classroom. For the handwriting I use a Bamboo brand tablet.
Dexter Cain Not only are they on the borders, they are at the intersections (corners) of the boarders. I don’t remember the name of the theorem that proves that. I might have referenced in the video.
Mr. Thomas would you be so kind as to show me your earlier lesson. The one where you taught to how graph systems of inequalities to find solutions. Thanks.
We are in 2018 and you posted this on 2012 and you still saving lives, god bless you man
No he is not i'm still dying
Im in a 3 hour lecture class and my professor attempted to lecture linear programming in 3 hours.. and I learned how to do it in about 15 minutes with this video...
My teacher did it in 5 min so I have no idea what to do.
We are in 2020 and you posted this on 2012 and you still saving lives, god bless you man

I'm not old! I've just been around a long time!
@@mricet1005 Hahaha... sorry sir; my bad!! But you are definitely a great teacher though!! Glad to have you reply on my comment!!

@@mricet1005 Thanks A lot . Sure will, and recommend your channel to others.
Great example of LP. Clarified many questions I had. I appreciate you not skipping over the "simple" stuff and working all aspects of the word problem.
Thank you! I'm a homeschooling mom to three teens and this really helped explain linear programming when we became stuck!
my teacher makes it sound so hard and you make it look so easy got a a test on this tomorrow so thanks man
How did you do on your test after learning it the day before? I have one tomorrow
Doing this is my last year of high school right now, and we have no teacher! This has been so helpful, thank you so much!

Its 2019 & this is the easiest lecture I've had on linear programming/optimization. Wish I had this when I was in the university in '97.
Emeka Ofordile Thank you.
operational researching is tough, and thank you for making linear programming simple to understand.
calming voice and a perfect presentation and example in order to explain linear programming, and you made it look so simple because it is the way you taught it! I was having troubles before and now I understand it, thank you so much!!
Glad it helped you. I have lots of other tutorials on various algebra and calculus topics too that you may find useful. Best of luck!
Thank you! We were asked to do a project which involved LP although we never learnt it! This video solved half of the problems I faced! THANK YOU so much!
you are the best. great tutorial. you just deciphered a foreign language for me
Thanks for your explicit explanation. It has been of great help to me. Won't hesitate to recommend
Best example I've seen yet! Thank you. I was about to withdraw from my finite class.
You are simply the best, very thorough and easy to follow.
very helpful! just struggled with this in my Masters today but this video resolved everything!
This was so helpful! I have been working on this in class for days and have not understood it but after this video I totally get it and I'm confident for my test. Thank you so much!
holy marony I can't believe this is so easy actually
you are a god
gay?
Amir Waraich what?
i love this tutorial. it has helped me a lot to understand what linear programing is all about. thanks Mr. T. I appreciate your efforts
Very helpful, I was really struggling with the linear programming basics. Strongly recommend it to MBA students, and all others of course!
thanks for the explanation.
We have two products x and y,
Max profit Z=12x+10y s.t
1- 30x+20y
I just finished a systems optimization class and this helped clear some of my confusion. Thanks!
short simple and straight to the point,,,,so helpful thanks
its good,but i

This video is very clear to understand and it helped me better understood Linear Programming
Excellent example with a good step-by-step procedure.
this video really helped. i'm not sure if it was me or my teacher but i just did not get it at all and this video makes alot more sense
This is so easily explained. Thank you so much Sir Randy Thomas.
wow finally i got a good teacher......Before that i was having rough time with linear programming
Thank you so much for the elaborate tutorial! Had completely forgotten how to solve it but thanks to you it's as if I learnt it yesterday! Cheers
Great tutorial, I use this to calculate both the voltage across a LED... and for accounting to max profit.
Thanks so much I learned from this video better than the 5, 45 minute class periods my teacher used to teach this
That was amazing. wow... been trying this for hours and now I know this in 15 minutes. just... wow. Thanks so much.

Thanks sir, very helpful. Helps much better than the lecture notes I read. God bless you sir.
Very clear explanation and very good example to demonstrate!
Very clear. I'm also studying for my master's and this really helped. Thanks!
Thanks sooooo much you made this problem look so plain and clear to understand!!!!
The video has made things quite clear in a simplified way. Thank you. I just have one question: why did you multiply the equation x +y = 240 by a negative and can we do that with every equation we formulate in linear programming?
Have A math test tomorrow and this helped me get ready. Thanks
Very helpful, easy and well explained.
Thank you very much.
Very simple and direct. Thank you.
What programme is he using to write all this? Would be much appreciated thanks in advance!!
I am a simple man, I understand, I subscribe.
good morning M Randy, I would like to know where u use Lpsolve 5.5.2.0 for linear programming , if yes do you have a video for that . i have to use it ! thanks
helped me in my research(starting phase) for image segmentation
very nice lecture. what software are you using to draw? I need to submit my homework with a digram ike the feasible region. thank you in advance for your help.
Thank you very much. This quickly reminded me the basic LP
Thank you for this clip...really helpful.hope for example on complicated questions because exam always came out with hard questions..
Very Detailed Explanation. Thanks!
you did an excellent job explaining sir
Thanks so much
Why are the max and min correspond to one of the vertices of the feasible region? Excellent tutorial by the way...
best tutorial ever, now i will be able to nail this in my exam
Really great video - explained clearly and concisely.
Thank for this help - final part of my test tomorrow not fully clear on ;D
Hi Mr T. Thanks, great video. Could you do some more with a manufacturing example ?? really helpful video ty.
OMG this topic is actually easy... thanks a lot Mr T
Thank you so much! your tutorial is very helpful and easy to understand
great video..helpful for my final exams..
best video thus far
Awesome videos, Really helpful to understand linear programming..
This found to be really helpful & nice presentation.
Great video. Thank you so much! Thank you for the historical reference too.
thank you!! I have a test tomorrow and this video saved me. :)
This is exactly what I needed! Thank you!
Hi, i've a question: make a linear model in linear programming by disributing a 8 queens in chess where each queen doesn't contact with eachother in distance
Thank you, very easy to follow and understand.
9:23 I didn't get, why we can draw line for x+y=
Which app or software you are using to teach
thank you for this mr. thomas, it really help me for tomorrow's exam...
Really good simple explanation, thank you.
hi, may i know the software/programme that you use in the tutorial? is it visio?
is it possible to go over the assumptions of linear programming?
Excellent Example. Thanks a ton.
Thank you Mr.Thomas.

thanks so much sir .i have learnt a lot from you.
thanks it is interesting and very beautifulinterpretation
Randy--Why the max or min occurs at end point?
Are the extrema always on the borders of feasibility though? How do you know there are no other extrema inside?
Dexter Cain Not only are they on the borders, they are at the intersections (corners) of the boarders. I don’t remember the name of the theorem that proves that. I might have referenced in the video.
Very helpful video, thanks
You are fantastic sir!
