Given a number n , find all prime numbers in a segment [ 2; n] . The standard way of solving a task is to use the sieve of Eratosthenes. This algorithm is very simple, but it has runtime O ( n log log n) . Although there are a lot of known algorithms with sublinear runtime (i.e. o ( n) ), the algorithm described below is ...

Did you know?
The sieve of Eratosthenes is a popular way to benchmark computer performance. The time complexity of calculating all primes below n in the random access machine model is O(n log log n) operations, a direct consequence of the fact that the prime harmonic series asymptotically approaches log log n. It has an exponential time complexity with regard to input size, though, which makes it a pseudo-polynomial algorithm. The basic algorithm requires O(n) of memory. WebPritchard [17] showed how to apply a xed wheel to get a compact sieve that runs in linear time. Atkin and Bernstein [1] gave the rst compact sieve that runs in sublinear time. For …

WebA prime sieve is an algorithmthat finds all prime numbers up to a given bound n. The fastest known algorithms, including Pritchard’s wheel sieve [16] and the Atkin-Bernstein sieve [1], can do this using at most O(n/loglogn) arithmetic operations. The easy-to-code sieve of Eratosthenes requires O(nloglogn) time, and there are
