WebMar 15, 2012 · The function log log n grows very slowly; for example, log (log (10^9)) = 3. That means you can effectively treat the log log n part of the time complexity as a constant, and ignore it, giving a time complexity of "nearly" O (n). There are various algorithms that operate in time O (n) or O (n / log log n), including Pritchard's wheel sieves and ... WebJul 7, 2016 · The maximum of such list is far smaller than mentioned 500-digits. Due to the prime number theorem π ( x) ≈ x / log ( x) so one could estimate that the list of prime numbers up to x would require at the order of x digits to represent. So by using the sieve of Atkin the complexity is O ( x) for both time consumption and memory consumption.
