I think it's very interesting how some people are repulsed by the use of mathematical symbols in the sample code. While others love it.
The vast majority of the code I write is not mathy. But I do write a fair bit of mathy code because of the field I operate in. Because of this, I'd side with the ones that hate it for some of these algos: the various sorts, for example. But for others, the use of mathematical symbols brings clarity, IMO. Assuming you already know the algo.
I've had to translate mathematical notation from a set of papers into code before. When I first picked up Julia, I re-did something I had previously done in Python/pandas/numpy. I used mathy notation... and julia code, ended up both MUCH clearer and quite a bit faster. I call that a win in my book.
