Are there any O(1/n) algorithms?
...east until some limit, enforced by the hardware (precision of the numbers, minimum of time that sleep can wait, time to process arguments etc.): this limit would then be a constant lower bound so in fact the above function still has runtime O(1).
But there are in fact real-world algorithms where th...

...l, but it's equivalent) for 1000 inputs; then repeat 7 times, and take the minimum. You need the averaging over 1000 inputs because you want the average (not best-case) algorithm complexity. You need the minimum for precisely the reason you gave. I thought I can improve your approach by choosing one...

...en accurate sleeps within several milliseconds of that time when above the minimum 10-13ms.
Update:
Like mentioned in the docs cited below, it's common to do the sleep in a loop that will make sure to go back to sleep if it wakes you up early.
