WebNov 8, 2024 · Sieve of Atkin. Sieve of Atkin speeds up (asymptotically) the process of generating prime numbers. However, it is more complicated than the others. First, the algorithm creates a sieve of prime numbers smaller than 60 except for . Then, it divides the sieve into separate subsets. After that, using each subset, it marks off the numbers that … WebThe algorithm is based off of pseudocode given by the reference to the Sieve of Atkins above.

WebA prime sieve or prime number sieve is a fast type of algorithm for finding primes. There are many prime sieves. The simple sieve of Eratosthenes (250s BCE), the sieve of Sundaram (1934), the still faster but more complicated sieve of Atkin [1] (2003), and various wheel sieves [2] are most common.
