Well, then now to the second drawing: How does an algorithm work? What did you draw there I just wanted to write down an equation first, it's basically like an IQ test. So for me, an algorithm works like you want to represent something specific and like an equation and in the end something specific has to come out and that's actually there... Can you be specific, so here's the first one, you have a box in the middle is a line on the left side is a circle and then comes an arrow and again a box and now the line is horizontal, before it was vertical and the circle is in the upper third. Why did you draw it like that? Yes, this is supposed to be quasi once, it is mirror-inverted what is above and below. Ah okay And that is supposed to represent, so to speak, that is simply a representation of some problem, is supposed to represent that. So this is a problem and what happens to it? Why did you draw it exactly the way you drew it? That should just be a representation of the problem itself. Okay. This is basically the representation for me, an algorithm is always some equation for me. The one on the left and the one on the right, so. And this mirror-invergence should actually just be the representation of the problem that the algorithm is supposed to describe. Okay, good. Okay, good. Thank you.
