Thank you for making this clear. My uni lecturer kind of glided over this with too much theory not really explaining it. 44 mins in when you said that its the slack dotted with the variable vector made it all clear.

Thank you so much! I have a optimization analytics course, but my professor goes through everything quickly and unclear. Your lecture is such a good explanation for both theory and examples.

Thank you so much!!! The old school teaching style and examples you used in your lecture helped me a ton (the last time I've taken any math related courses was 10+ years ago).

For the second constraint of the dual isnt that supposed to be just y2 instead of 2y2

The explanation is great and clear. However, At 40:50 should the dual constrains all to be "smaller than or equal to" because x1 to x4 are all larger than or equal to 0?

Good day madam, at 46:09 how do you know if inequalities 2 and 4 couldn't help you therefore you must stretch them out.
