How is the algorithm works? Like the first one. You can take some example or whatever, you're completely free. Algorithm specifically? They are somewhat of the same pattern but. Here, D means realization; I can not honestly say how to explain this. Just explain, I mean, what did you think about, I mean how would you explain this drawing now? Well, I do not know, on the basis of those, let’s say, the idea I just formulated it differently. Basically, based on this collected data, I do not know, some of them get to realization. Something like this. I honestly do not know exactly how to explain it now. So that's it, that's your process, algorithm? Yes. And how do you know, about how algorithm work? How do you know the algorithm? Some assumptions, I do not know either. Did you learn about it or? Well, I more… it's somehow through talks. Now I do not know, maybe I totally wiped it off; I think maybe I made completely a mistake, maybe. It is someone I see.
