Easy to follow, clear handwriting, complete explanations with context, online, considerate towards diets/philosophies/politics, and a calm voice to keep you engaged for longer without even realising it. Thank you so much for the lecture, this is great stuff.
thank you, ma'am, I'm here in 2020. honestly, you did justice to this course. I am no longer afraid of taking my exams on Monday. you just simplified OR for me.. I am grateful.
The kids don't appreciate the opportunity. If I could do my undergrad over again I'd be appreciative and ask questions every 2 minutes. I'd probably be a pest. Appreciate your education, you only get one shot.
Thank you for the course, for those who are curious about the book it's called "An Introduction to Linear Programming and Game Theory" by Paul R. Thie, Gerard E. Keough published in 2008
I followed your videos with a lot of interest and pleasure. I think they are some of the best on TH-cam. They are with a simple and very convincing didactic. I'm a professor and I teach linear programming too. It's my first comment on TH-cam so thank you very much for sharing.
Thank you very much for your lecture. I had no idea about linear programming and I need it for my PhD project and now I've learned a lot thanks to you. You explain very clear each detail and take the time to do all the necessary steps to understand the method. It's shame your students were not that enthusiastic at that moment. Thanks again!
Thank you for uploading your lectures for free, professor. A lot of working class people really rely on this kind of open source education. Probably more than they realize. Also, I'm sorry you are allergic to so much good food.
Why didn't youtube showed me this playlist before two months, I could have learned a lot with these videos, it is so nicely explained !!! Thank you Professor
As a university online student doing business design and analysis subject which essentially is introduction to LP, I've used your lectures in lieu of my own university. You articulate very well!! From Australia.
Very patient teacher and a very well prepared one, with a very beautiful handwriting. I loved this lecture and I and going to follow your lectures regularly. Regards.
It's been almost 3 years now, thank you for uploading and keeping these LP videos on utube. I'm currently taking LP class at UBC (Canada) and we're using a different and slightly simpler method to solve LPs...however, they way my prof. delivers the fundamental concepts are very vague. There are still a lot of confusions in my class as to why...things are...where did the equations come from etc...and since I'll be taking Machine Learning later on, I'm glad that I found your lecture videos, very clear explanation. And many other Canadian universities also use canonical form....and I hate to collaborate with teams and says...use Anstee's rule....lol I guess everyone will be confused since this rule is....UBC exclusive.
WOW, I am really impressed. Thank you for putting this video online. I wish you were my linear programming teacher..... I rarely post comments, but once again. Thank you!
my spv asked me to learn simplex method straight from the book and i spent 2 days to understand it. However, I was a mess because i didnt get any fundamental theory behind it. After i watched your video, everything has come to light. Thank you!
Thank you for the lectures. For those who are thinking whether to watch them, I can say that the lectures are not difficult, there is no advanced math. All explanations are very clear and supported by lots of examples.
for any one annoyed about the audio being on one side (on windows laptop) you can go into settings, ease of access, audio, turn on mono audio, then the audio will be in both ears, turn it off after
Thanks for this professor! May I know where can I get the resource materials you used for this lecture? If possible, do you happen to have a soft copy of these? Thanks!
Y'all the folks that are listening through their right earpiece, go to the "windows settings" and turn on the mono audio settings. It is magical on how quickly it works. PS: Watching this playlist for the first time. Will update again once I'm done with this. Seems to be nice.
Thanks a lot for sharing your lectures, dear professor! I find them very well explained and structured. It helps me a lot to learn numerical computation. Now I am gonna watch more of your lectures. Big thanks and Best wishes to you!
She's so sweet I want her to be my lecture.. I'II drop my email so we'll able to keep in touch or I could also drop my WhatsApp number so I could get a proper lecturing.
Thank you very much for this lecture video! This is a very clear explanation of Linear Programming to me, and I also learnt quite a bit on how to explain this to other people :)
Life-saving lectures. Very well explained. Thank you very much. The series ends with lecture 27 - do you have the remaining lectures available also? Assuming some network-flow also comes?
Dear professor, is there any way to know the what the problems you have assigned from the textbook for the homework? So that online audiences could have a chance to solve them.
It was helpful and clear. Many many thank you for uploading this video for us. Though I have a question about the lecture. In the second lecture this is solved - you took care of slope of the lines. But here I can't see it, that's why I ask. How do you know that those lines (the boundary of feasible region, and the line of minimum cost function) has this shape as you've drawn? I'm talking about the plot you have plotted in 59:00 minute. Exactly about slope of the lines. In the linear function f(x)=ax+b, a tells about the slope of the plot function, b how it goes up and down. So - AS I GET (maybe here I am wrong) - you didn't check on slope of cost function and the boundary of feasible region, before graphing them. So how do you know, that actually this two lines aren't actually "reversed"? I mean the cost has boundary shape and the boundary has cost shape. How do you know that boundary is more parallel to the x (here A) axis, not the other way? This is important, because then, the answer would be 175 on A (Apple) axis, not the 58.3 on B (Bananas :)). So you've plotted lines without particular chiecking their slope, and then read it like it was accurate... that's why I have my anxiety. Uhh, sorry for asking this so trivial-stupid and not proffesional way, but I had to ask it clearly... I really hope for your answer. Again thanks for upload!
Heh, I got also one more question... at minute 1:04:51. Cost function is z=8A+10B. You say: if A is constant, this is a linear function of B. To this we can apply that classic linear function model y=ax+b. Then if A is constant, it becomes kind of y=10x+constant (B becomes x to this model and z becomes y). You say of course also if B is constant, z is linear function of A. Then it goes y=8A+constant. And my question is... what if both A and B aren't constant? If they are just A and B - variables (not constants)? Then this function is set of parallel lines? Exactly a set of control lines, that you draw at 57:38? Actually i guess all you have to say is just "Yes", haha because i think that's the way. It just lacked for me that words at 1:04:51 what happenes if none of them is constant. I just can't visualise how function behave with two variables, and when one variable changes how it goes with second variable and with plot. (this is lack of teaching me function of two variables on calculus, I hadn't it in my course).
Sometimes the problem is very tricky. How should I not to be fool by problem? What steps I need to follow to have better judgement? I know also that we have three main rules, decision variables, objectives, constraints.
Linear Programming has always been a very opaque topic for me. This is the first LP lecture that did not give me a massive headache and turn me into a quivering mass of jell-o within the first 5 minutes. Very understandable; great teaching style. Thank you so much! Welp, I'm off to the grocery store to buy 58.3 bananas! (JK)
Awesome lectures, learning matlab now, in OR 2, wanna refresh everything as i want to enter the field in my career. Thank you providing quality lectures.

She explained well, but I am sure I am not the only one who got lost on drawing the cost function....how did she arrive at 58? Someone help out.
a big respect and thanks for these tutorials while am searching good ones about LP for my little sister.

how did she come up with the constant k = 80?
why the Mini point would not be the 20 the last point the slop touch in feasible region is 20 ?! and thank you
She lost me at k. Can someone explain. Her plane example I couldn't visualize well. Help.
Dear professor,
I’m confused, why the corner point is a minimum cost?
