  2. Sieve of Sundaram - Wikipedia

    en.wikipedia.org/wiki/Sieve_of_Sundaram

    The above obscure-but-commonly-implemented Python version of the Sieve of Sundaram hides the true complexity of the algorithm due to the following reasons: The range for the outer i looping variable is much too large, resulting in redundant looping that cannot perform any composite number culling; the proper range is to the array indices that ...

  3. Sieve of Eratosthenes - Wikipedia

    en.wikipedia.org/wiki/Sieve_of_Eratosthenes

    The sieve of Eratosthenes is a popular way to benchmark computer performance. [14] The time complexity of calculating all primes below n in the random access machine model is O ( n log log n ) operations, a direct consequence of the fact that the prime harmonic series asymptotically approaches log log n .

  4. Sieve of Atkin - Wikipedia

    en.wikipedia.org/wiki/Sieve_of_Atkin

    The following is pseudocode which combines Atkin's algorithms 3.1, 3.2, and 3.3 [1] 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 version of the algorithm that supports optional bit-packing of the wheel; although not specifically mentioned in the referenced paper, this ...

  5. Legendre sieve - Wikipedia

    en.wikipedia.org/wiki/Legendre_sieve

    In this example the fact that the Legendre identity is derived from the Sieve of Eratosthenes is clear: the first term is the number of integers below X, the second term removes the multiples of all primes, the third term adds back the multiples of two primes (which were miscounted by being "crossed out twice") but also adds back the multiples ...

  6. Sieve of Pritchard - Wikipedia

    en.wikipedia.org/wiki/Sieve_of_Pritchard

    A prime number is a natural number that has no natural number divisors other than the number 1 and itself.. To find all the prime numbers less than or equal to a given integer N, a sieve algorithm examines a set of candidates in the range 2, 3, …, N, and eliminates those that are not prime, leaving the primes at the end.

  7. Binary translation - Wikipedia

    en.wikipedia.org/wiki/Binary_translation

    A translator using static binary translation aims to convert all of the code of an executable file into code that runs on the target architecture without having to run the code first, as is done in dynamic binary translation. This is very difficult to do correctly, since not all the code can be discovered by the translator.

  8. Source-to-source compiler - Wikipedia

    en.wikipedia.org/wiki/Source-to-source_compiler

    A source-to-source translator, source-to-source compiler (S2S compiler), transcompiler, or transpiler [1] [2] [3] is a type of translator that takes the source code of a program written in a programming language as its input and produces an equivalent source code in the same or a different programming language.

  9. Eratosthenes - Wikipedia

    en.wikipedia.org/wiki/Eratosthenes

    Eratosthenes of Cyrene (/ ɛr ə ˈ t ɒ s θ ə n iː z /; Ancient Greek: Ἐρατοσθένης [eratostʰénɛːs]; c. 276 BC – c. 195/194 BC) was an Ancient Greek polymath: a mathematician, geographer, poet, astronomer, and music theorist.
