Exponential hierarchy

Okay kiddo, have you ever heard of a hierarchy before? It’s like when we order things from best to worst or from biggest to smallest. The exponential hierarchy is like that, but it’s for problems that can be solved by a computer.

Let’s say we have a really hard problem that we want the computer to solve. We can ask the computer to solve it, but sometimes it takes a really long time. We can measure how long it takes by counting how many operations the computer has to do.

Now, let’s say we have another problem that seems even harder than the first one. We can ask the computer to solve this one too, but it takes even longer. And if we keep making the problems harder and harder, the computer will take longer and longer to solve them.

So, the exponential hierarchy is just a way of organizing these problems based on how long they take the computer to solve. The problems at the bottom of the hierarchy are the easiest for the computer to solve, and ones near the top are the hardest.

But, don’t worry too much about it for now. It’s a very complex topic, and we’ll learn more as we get older and have to solve harder problems.
