Talk:Sunflower fractal
This is not a fractal
This is not a fractal. Fractals are self-similar under different magnifications. This pattern is not. It would be more accurate to refer to this task as "Fibonacci packing" or "Phi packing" See http://www.maths.surrey.ac.uk/hosted-sites/R.Knott/Fibonacci/fibnat2.html and https://www.mathsisfun.com/numbers/nature-golden-ratio-fibonacci.html.
- Hello,
- May I am not right but see the next link:

- That page is simply wrong. This sunflower picture is not a fractal.
- In colloquial usage, "fractal" is often taken to mean merely "self-similar", whereas more rigorous usage might also speak of its Hausdorff dimension. Clearly the logarithmic curve is self-similar (zoom the origin to any scale and it looks "same"), but it never gets any more "detailed" - still just a one-dimensional (topologically) line at any scale. (contrast that with what happens when you zoom the Mandelbrot set or a Hilbert curve) But, the real problem here is that the task is insufficiently described anyway - containing only a link to a long-dead page that not even the wayback machine has a copy of.

Tasks need a description
In addition to the controversy mentioned on this page about whether this is a fractal, the task description is not adequately explained on the task page and instead is mostly a dead link.
Currently, there's no objective way of determining whether any implementations satisfy the task requirements. --Rdm (talk) 06:44, 18 September 2021 (UTC)
Dead Link
Not only dead, but was originally to a personal Onedrive location. That doesn't seem stable enough to base a task on, as we now know.

- Yeah, it is not the best link (got a better one?), but it might be ok for "anything like any of these will do"?
- Or maybe collect the existing links scattered throughout the task entries up into the task description. --Pete Lomax (talk) 12:01, 18 September 2021 (UTC)
