Why not? OP asked for algorithms and explicitly said they didn't have to be state of the art. Then saying them not being state of the art is hardly relevant?

And an algorithm can be based on a metaphor and still be useful, one should just take care to judge it own its own merits and not give it some greater value for being "natural".

Yeah I know most of these algorithms are not state of the art. That's why I explicitly said that. Still, I find it interesting to read about them. It satisfies a curiosity of mine, hopefully shared with other people here too.

HN comments aren't StackOverflow answers. They're allowed to go off on tangents. Personally, I like to see nuances that I didn't before and so appreciated and upvoted the comment.
