WebAug 24, 2024 · Is your sieve actually better? I modified your code to at least count the number of primes instead of outputting and it appears correct for N=10^8, 10^9 (see table). There are a lot of floating point calculations going on, compared to the standard Sieve of Eratosthenes, and both still fit the whole array into memory for N <= 2*10^9.

WebLike your code, this is still not really the Sieve of Eratosthenes because, for example, it will futilely try to cross off multiples of 6 and 9 etc. Nevertheless it still runs significantly faster than most other Sieve look-alikes for values less than a million or more, since for small N there are "about as many" primes as non-primes (the fraction of numbers < N that are … WebA prime sieve is an algorithmthat ﬁnds all prime numbers up to a given bound n.
