In this question the user asks an interesting and natural question: "A computer has produced this list of numbers. I want to know how it does this." Unfortunately, this question cannot be answered without using the word "probably". In fact, the answer to the question as posed is "No, you can't". However, simply saying "No, you can't" is not good enough. It should be "From a mathematical point of view no, you can't and here is why, but from a real-world point of view this is what they probably did". Personally, I would be intrigued to see the answer of someone who actually knew their stuff, some who can say "They probably did this, because that is the standard approach", or "Some people do this, others do that. Going by your samples, it is probably this third, obscure option." Note that the approaches would all be mathematical, and so such an answer would be well within the remit of this site.
However, no such expert appeared before three people said "Oh, well, they maybe did this"...and so the question has been closed. Because if you try to answer it as a purely mathematical question it only admits opinion based answers (unless you say "No, you can't! And here is why..."). Personally, I think closing it is unfortunate.
*My point is, if we are here to help people understand stuff then closing this question is pointless - it admits an answer, just not the kind of answer the OP wants.**
My question is: what should be done in this and in similar cases? You see, the three answers are all useless and it is not unlikely that we will never get someone who knows enough to answer this question satisfactorily. So is just closing it better? This would stop spammy internet-point-seeking answers...but that isn't the point of this site.
*If we are here for internet point, then sure just close it.
