(defn smearfle | |
"\"Smearing shuffle\": shuffle a list while semi-preserving its original order. | |
Slide a window of size `window-size` (default 3) across the list from left to right | |
in increments of `step-size` (default 1), shuffling the contents of the window on each step. | |
The end result: some items are carried a random distance left or right of their | |
original starting point, but disruption of the list's order is largely local, | |
so it's unlikely that any given item is (for instance) carried all the way | |
from the beginning to the end of the list. | |
You can use this to add some variation to the order in which a sorted list is traversed, |
