What is Complexity Theory?

Here we start a new series on complexity theory, which is asking the question about how efficiently we can solve various problems. We classify languages into sets based on certain properties (poly-time solvable, randomized, etc.) and see how the sets relate to each other.

▶ABOUT ME◀
I am a professor of Computer Science, and am passionate about CS theory. I have taught many courses at several different universities, including several sections of undergraduate and graduate theory-level classes.

I am really liking your channel, its helping me prepare for next semester classes. Thank you very much!

[HighlyShifty]

You are an absolute legend for doing this, thank you

Let's go Easy Theory, now I'll understand what NP, Co-NP, P-Space, and all that stuff is. Until now I kinda get it but not really but yay, high hopes for this :)

Bro, you are gonna save me! Your videoes are awesome!

Even though the lines between mathematics and theoretical computer science are often blurry, what different perspectives would either field emphasizes?

Can you do videos on proving the correctness of a DFA for a given L(M) for machine M? So questions where they give you a machine M and ask you to prove that the L(M) is all strings with even 1s. I think it's normally done with induction.

Is it okay to watch this series just after watching your 12 hour live stream? Or is it necessary to watch all of 140+ intro ToC videos in order to understand this series?

A bit jargony not too beginner friendly
