Tangential, but this brought me to https://en.wikipedia.org/wiki/Bogosort, and I love a sorting algorithm "Miraclesort":

> A sorting algorithm that checks if the array is sorted until a miracle occurs. It continually checks the array until it is sorted, never changing the order of the array.

It basically waits for god intervention / single event upset. It is guaranteed to be optimal in at least one quantum universe, though.
