Puzzles - how are they chosen?

Hey guys and Gals... Does anyone know how the puzzles are chosen? There are many which have better moves than the solution, others that have two or more ways it can be solved and so many others that are the result of poor decisions from the opposing player and which you could never imagine they'd make. Any feedback is much appreciated, tDoC.
They are chosen from games played on the site. Can you please link any puzzles which have ambiguous solution? (maybe you just don't realize why the solution is stronger?!)
Vetinari, no, I'm quite capable of knowing which is a better move and/or what are mistakes/poor decisions that leave pieces hanging and which you cannot account for. It's why there is a vote up and down button, I guess, as it must be well known that many slip through with more than one solution, better solutions or that just aren't proper puzzles. That's all by-the-by. I just wondered how they are generated and IOExceptional seems to have answered. I;l have a quick look at the link now. Thanks to the both of you.
OK, I understand even less after reading that! Gawd. But with the amount of work and time that the programmer put in, and working out an algorithm that is even 95% accurate, having a few slip by then isn't such a big deal. I'll have to read that article again when I'm drunk... May make more sense that way.
If you're so sure that these puzzles are wrong why you don't bring examples? You can't just complain that puzzles are wrong and then not even show one.
@the-death-of-chess
you're wrong.
I did more than 1000 puzzles and I haven't yet seen a puzzle which have better moves than the solution.
Before you complain, prove it with examples.
Some moves suggested by the puzzles are sometimes accurate, but not compulsory... For example, My knight could give a discovery in its 8 possible squares, and all would be winning... But only one of them would be PRECISE. Also, I can go for intermediate moves... These are not wrong, for example, I could improve the position of my knight with a check and then solve the problem... I might have a better advantage by that way. Just saying.
TY
Yes, a few puzzles are weird. Eg. comp sacs a queen because that is better than being mated in three. However the task is to see the mate in three. This could have some hand crufting by a puzzle admin.
Cuxhaven, no I'm not wrong and I will not be proving anything by examples as you have just done what is absolutely rife in every online forum and answered a question that wasn't asked. My question was: how are puzzles generated? Now, that question has been answered by someone who was able to understand very basic and concise English and the answer is not: they are generated by posting examples here as I have done 1000 puzzles and have gotten them all right. If you want to prove your answer is correct and post all 1000 puzzles you completed then be my guest. However, I wouldn't even glimpse at such nonsense as it isn't what I wanted to know. O, and you should maybe read the article on how puzzles are generated as it explains it is far from fool-proof due to te complex nature of the algorithms. If you like feed the puzzles into stockfish and the poor fella also finds multiple different answers. You'll also find puzzles that have been played 60,000 times and only have a few likes. But I guess 50,783 people are all wrong and you're right. Hmmm... I smell something in the air and it smells rather similar to when I lose control of my bowels during pressure strung time-controlled endgames.

Advice: if you can't answer the question then please refrain from typing up your irrelevant and dishonest gobbledigook. I love you man and always will, but when you'e wrong you're wrong and as one of your greatest admirers I have a duty to pull you to task whenever you are - and today you are. X
