This is a fast prime number list generator using sieve algorithm. This function return a list of prime numbers which <= argument.
primepow(aNumber) finds the prime number P and power N of aNumber such that aNumber = P^N.
The implementation is heavily borrowed from Art Owen <a href="http://www.csit.fsu.edu/~burkardt/cpp_src/oa/oa.html">Orthogonal...
Lightweight prime number generation library. Makes use of OpenMP and aims for performance. Suitable for applications in cryptography or just for educational demonstration.
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...
This program implements primality testing function. The function is then used to generate prime numbers in the given range.
Since the excellent <a href="http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/366178">fast prime number list generator</a> recipe, it's simple to implement a function to check if its input it's a prime number.
Using python 2.6 & numpy. This code was first posted here
Input parameters p : odd prime number deg: positive integer (default value = 1)
Output is a (p^deg+1) by (p^deg+1)/2 matrix E
When deg > 1, the communication toolbox is required

A one-liner that returns the list of prime numbers up to n. The inner lambda is the sieve.
Uses an array to store the values, expands the size of the prime list on the fly, you can make a guess at how many you will need. I am finding it useful for the problems at http://projecteuler.net Any thoughts for improvement appreciated...
Maximum length sequence assuming distinct values = baseVal^powerVal-1
[ms]=mseqSearch(powerVal,baseVal) OUTPUT: ms: generated maximum length sequence, of length basisVal^powerVal-1 such that all values...
how to solve the attached problem in genetic algorithm for association rules. 1) plz concentrate on table-1, table-2 and table-3 here we are looking for series whose numbers are not increasing as number of items increases...

MPN_FPN.m : This programme creates Mersenne Prime Numbers and Fermat Prime Numbers. We are however, limited in the range here because MATLAB's isprime()is limited to only 2^32.
General hash function algorithm implementations for series of commonly used additive and rotative string hashing in the object pascal programming language.For more information please visit:http://www.partow.net/programming/hashfunctions/index.html
AddUp 2 could be the last calculator you will ever want. With a flexible work area and user-selectable button panels, this multipurpose tool packs all the functionality you can expect in a calculator.A flexible work area lets you type in your...
The program can simulate fast Tanner LDPC codec with quasi-circular generator matrices, and 1/2 code rate. Copyright (C2010-2015) Yang XIAO, Beijing Jiaotong University, Nov.3, 2010, E-Mail: yxiao@bjtu.edu.cn. Current Version...
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.
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...
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.
Very rarely it is necessary to find the multiplicative inverse of a number in the ring of integers modulo p. Thie recipe handles those rare cases. That is, given x, an integer, and p the modulus, we seek a integer x^-1 such that x * x^-1 = 1 mod... |
