## Description

**Mtsieve** is a multi-threaded sieve framework for different sieving programs developed by Mark Rodenkirch.

## Included software

The package contains all C-sources and Windows executables.

The following tools are included:

- afsieve: search for factors of Alternating Factorials
- mfsieve: search for factors of Multifactorial numbers
- cksieve: search for factors of Carol-Kynea primes
- pixsieve: search for factors of a long decimal string where each successive term adds on decimal digit to the end of the previous decimal term
- fbncsieve: search for factors of numbers in the form
`k`•`b`^{n}+1 and`k`•`b`^{n}-1 for fixed b and n and variable k - fkbnsieve: search for factors of the form k*b
^{n}+c for fixed k, b, and n and variable c - gfndsieve: search for factors of
`k`•2^{n}+1, remaining terms are potential divisors of Generalized Fermat numbers - kbbsieve: search for factors of numbers of the form
`k`•`b`^{b}+1 or`k`•`b`^{b}-1 for fixed k and variable b - xyyxsieve: search for factors of x
^{y}+y^{x}and x^{y}-y^{x} - gcwsieve: search for factors of Gen Cullen primes and Gen Woodall primes
- psieve: search for factors of Primorials
- twinsieve: search for factors of twin primes
- dmdsieve: search for factors of numbers of the form 2*k*(2
^{p}-1)+1 (potential divisors of Double Mersenne numbers) - k1b2sieve: search for factors of the form 2
^{n}+c for variable n and c - sgsieve: eliminates terms for Sophie-Germain prime searches for base 2, fixed n and variable k
- srsieve2: search for factors of k*b
^{n}n+c for fixed b and variable k and n
