Constrained Optimization: Intuition behind the Lagrangian

This video introduces a really intuitive way to solve a constrained optimization problem using Lagrange multipliers. We can use them to find the minimum or maximum of a function, J(x), subject to the constraint C(x) = 0.

had an undergrad professor so determined to stop cheaters that he only allowed scientific calculators which didn't bother me until he expected us to do regression

You are a single piece, bro. You're explaining intuitions, makes me excited all the time.

I really have to learn to try ideas and equations with simple examples. I was so afraid Lagrange multipliers and Lagrange equation and its sense that I just dropped it off. How lucky that I just saw with the corner of my eye that thumbnail on my recommendation list with a characteristic Brianish drawing style with the "Lagrangian" word within the title. I knew before watching that you will help as always. Gosh you are a great educator man.

Most inspiring video I ever seen. I got two takeaways: transferring none resolvable problem to an equivalent resolvable problem; gradient is a good way.

Brian, can you do for us a summer school course for control engineers I'll be the first one to attend if it's you talking about the intuition behind control!

[@Joshjson]

Wish this was the way it was explained in university. Liked and subbed

[@user-tp5bu8vf9b]

Can't see the video

[@faraway27]

Thanks Brian, I always look forward to new Tech Talks! Could you do a video on MPC? That would be awesome!

[@kmishy]

Great teaching❤

[@AngeloYeo]

Great as always! 🎉

[@Pedritox0953]

Great video!

[@harrytsai0420]

Nice video! Looking forward to the nonlinear constrained optimization part!

[@griffinbur1118]

Great video. In the interest of being precise and thinking about what might trip up new learners, someone who's paying really close attention will find
