WebIn mathematics, the sieve of Eratosthenes is an ancient algorithm for finding all prime numbers up to any given limit.. It does so by iteratively marking as composite (i.e., not prime) the multiples of each prime, starting with the first prime number, 2. The multiples of a given prime are generated as a sequence of numbers starting from that prime, with constant … Web^ a b Paul Pritchard, "A sublinear additive sieve for finding prime numbers", Communications of the ACM 24 (1981), 18–23.

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 floating handguard parts

A practical sieve … 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.
