It really depends. Often, we solve interesting looking problems either from random contests or new ones. If we find a nice solution, then we will present the problem. Sometimes, we also present problems, we had seen a couple of years ago and really liked. For example, I learned about this problem in a camp 3 years ago. Now, I saw something in university that reminded me of that approach and so I decided to make a video on this problem.
I think, this should also work with the Hasse-Weil Bound. Great solution and very creative!
Hey, how do you usually choose what problem to make a video about?
