Sieve of Sundaram
From Wikipedia, the free encyclopedia
In mathematics, the sieve of Sundaram is a simple deterministic algorithm for finding all prime numbers up to a specified integer. It was discovered by East Indian student S. P. Sundaram from Sathyamangalam in 1934.[1][2]
[edit] Algorithm
All the values in the form of z = i + j + 2ij are excluded from sequence of natural numbers,
where i = 1, 2, 3, ..., n and j = 1, 2, 3, ..., i.
The remaining numbers are doubled and incremented by one. The resulting sequence represents the sequence of odd primes (i.e., all primes except the only even prime 2).
