We introduce an algorithm that computes the prime numbers … In mathematics, the sieve of Atkin is a modern algorithm for finding all prime numbers up to a specified integer. Compared with the ancient sieve of Eratosthenes, which marks off multiples of primes, the sieve of Atkin does some preliminary work and then marks off multiples of squares of … See more In the algorithm: • All remainders are modulo-sixty remainders (divide the number by 60 and return the remainder). • All numbers, including x and y, are positive integers. See more The algorithm completely ignores any numbers with remainder modulo 60 that is divisible by two, three, or five, since numbers with a … See more • Sieve of Eratosthenes • Legendre sieve • Sieve of Sundaram • Sieve theory See more The following is pseudocode which combines Atkin's algorithms 3.1, 3.2, and 3.3 by using a combined set "s" of all the numbers modulo 60 excluding those which are multiples of the prime numbers 2, 3, and 5, as per the algorithms, for a straightforward … See more It can be computed that the above series of three quadratic equation operations each have a number of operations that is a constant ratio of the … See more • Article about Sieve of Atkin and Implementation • An optimized implementation of the sieve (in C) See more
