In mathematics, the sieve of Pritchard is an algorithm for finding all prime numbers up to a specified bound. Like the ancient sieve of Eratosthenes, it has a simple conceptual basis in number theory. It is especially suited to quick hand computation for small bounds. Whereas the sieve of Eratosthenes marks off … See more A prime number is a natural number that has no natural number divisors other than the number $${\displaystyle 1}$$ and itself. To find all the prime numbers less than or equal to a given integer $${\displaystyle N}$$, … See more Once the wheel in the sieve of Pritchard reaches its maximum size, the remaining operations are equivalent to those performed by Euler's sieve. The sieve of Pritchard is unique in conflating the set of prime candidates with a dynamic wheel … See more The sieve of Pritchard can be expressed in pseudocode, as follows: where next(W, w) is the next value in the ordered set W after w. where prev(W, w) is … See more An array-based doubly-linked list s can be used to implement the ordered set W, with s[w] storing next(W,w) and s[w-1] storing prev(W,w). This permits each abstract operation to be implemented in a small number of operations. (The array can also be used to store the … See more • Sieve of Eratosthenes • Sieve of Atkin • Sieve theory See more 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.
