A one-liner that returns the list of prime numbers up to n. The inner lambda is the sieve.
Finds the nth prime without using a sieve algorithm.
This is a fast prime number list generator using sieve algorithm. This function return a list of prime numbers which <= argument.
A simple implementation of the Sieve of Eratosthenes in Python. The code should be self-explanatory, but I've added a docstring and some comments just in case.
Constructive criticism is of course appreciated.
Basic idea was to see the difference between different prime algorithms in time. Also they are not perfect the output shows that really higher numbers let grow the difference why I have separated this into functions to make it visible. I add this...
This is an evolutionary algorithm that returns a random list of prime numbers. This code is highly inefficient for a reason. This algorithm is more of a proof of concept that if a prime was a heritable trait, it would not be a desired one.
It's an iterator that returns prime numbers.
Got the idea from here: www.cs.hmc.edu/~oneill/papers/Sieve-JFP.pdf
The algorithm is based on the idea
that the next larger prime after one prime is the sum of the two smaller previous minus three prime numbers back.
For the first five prime numbers 2,3,5,7,11 this pattern is not true also it is not...
sieve-of-eratosthenes algorithm with efficient scaling for big numbers.
A class Ive had in my snippets for awhile that can generate prime, perfect and fibonacci sequences as well as check whether or not a supplied value is any of them.
