2018年3月15日 · I have a question about Sieve of Eratosthenes, I refer at the "simply version" : If I have an $\boldsymbol{n}$ and I want the prime numbers up to n, I search and delete multiply up to $ \leqslant \sqrt n $ . For example: $ n = 28; \sqrt n = 5,29 $ After 5 I'm sure that I haven't delete multiply but I will find only prime numbers.

2015年2月28日 · What you have written, is not exactly the Sieve of Erathostenes. When doing the sieve, you don't do any divisions; you just step through all the numbers and cross off multiples. The sieve doesn't find the n'th prime, but rather all primes up to a limit. This is an example of how to do the sieve. It's a very basic version.

For example, sieve_eratosthenes(7u) returns a vector containing 2 3 5. This is due to the vector is_prime being too short by one element: it considers the elements between \$ 0 \$ and \$ n-1 \$ while it should consider the elements between \$ 0 \$ and \$ n \$.

2024年12月1日 · In the paper, O’Neill explains why the popular Haskell example of the Sieve of Eratosthenes is not, in fact, an implementation of the Sieve of Eratosthenes, defines what the "essence" of the Sieve of Eratosthenes is and what an implementation must provide in order to call itself an implementation of the Sieve of Eratosthenes, and provides an ...

2020年10月22日 · You can argue by contradiction. To make things clear, when I talk about a number's 'prime factors' I'm going to count multiple instances of the same prime distinctly; for instance, $36=2^2\cdot3^2$ has four prime factors: $\{2, 2, 3, 3\}$.

2023年8月24日 · The Sieve of Eratosthenes is a popular algorithm to find prime numbers up to a given limit. It is very simple and I find it very suitable to implement in a programming language as way to improve my skills. But it is also extremely inefficient. The basic version goes like this:

2015年9月8日 · An improved version Sieve32FastV2 is available.. The classical solutions for the Sieve of Eratosthenes fall into 2 camps: one uses a bool[], which is fast but very memory bloated; the other uses a BitArray, which is more sluggish but uses far less memory.
