An algorithm, drawn by a 63-year-old male retired sales manager in Germany.

So now you have only written f of x and an arrow. Why? Yes, because it's an algorithm. Just the unambiguous-- What did I say before? Clear [pause] solution, not solution. Clear instructions or actions to solve a problem. So I had this in my head at some point. So and this now in one function? Not a clue. So, why wasn't it for you-- F of x is a function. There is any set and I have a function and with this function I can formulate the set in instructions. And then it rakes with me. I didn't know how to formulate it. Why is it that you say you can't draw it? Because it's logic. Is a mathematical formula, I'd say, an algorithm. Okay. And I don't have this formulation in my head because I, I don't know how long, haven't used it or have forgotten it. Wait. In general: How did you learn something about how algorithms work? I studied statistics and it was about quantities. And there it was about causalities and correlations and then the term algorithm came up. Okay. You mentioned algorithms on the Internet in our conversation earlier. Is that the same thing? As far as I know, all search engines work with algorithms. Yes. Is that the same algorithm that you used in statistics back then, so to speak? I didn't map it to search engines back then. Back then it was just functions. The name algorithm was only used very, very rarely. Today it jumps into your way in almost every second article about new EDP or artificial intelligence. Maybe it has also become a bit of a fashion term. Thereby-- Whether it is then always used in the right context also, no idea. But if you think about the algorithm used there now, could you draw it? Could you draw what you mean by that? The formula. There was then, but I don't have it in my head anymore. But if the way it works, you wouldn't know whether...
