    Your teaching is so well! I came from SJTU too, I am now pursuing a Ph.D. degree in Operations Research. Thx so much!

      Thank you so much for your lectures, they're obvious and strengthened with real examples (not abstract like maths)

    You are literally my saviour! Due to overlaps with other lectures, I cannot attend the linear programming lecture in my university. But this is awesome, I can rework the stuff with the help of your videos now! Thank you so much!

    Many thanks professor , actually my profession is a far away from the pure math discipline but I have a solid elementary basics in mathematics so I took the advantage of that to strengthen my self on linear programming for the reason of some intersection related to some areas in my profession , so I deeply wish you all pest for and hope you accept my warm gratitude .

    Is there also not a constraint on x_4'' such that it must be smaller than x_4'? Otherwise it could render x_4 < 0.
    These lectures are amazing btw professor. Thank you for posting them!

    Thank you for your excellent lecture! I found one little mistake. For the observations that you summarized at 33:55, condition for m and n should be n >= m, instead of n > m.

      m and n might not be the same number.

      ​@@eddiezhuo4231 they def could be equal, so for generality, less than equal is appropriate here

    I want to scream take the negative to minimize! The look of concern in your eyes over no reply was funny.😂

    Hi,

    0:12:45
    Why is the maximize function converted to a minimize function?
    doesn't this totally alter the problem question at hand?

  • @dalang8485
    @dalang8485 6 лет назад +1

    I’m so confused now; CLRS says standard form is maximizing with inequalities. Why the difference here?

      You can define it either way. It doesn't matter. Thanks for watching.

      I'm the same way, always goes 2X speed, when data chunking in the beginning of the course.

    X1 and x2 are linearly independent, positive vectors.... They're feasible solutions...
