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•bn+1 and k•bn-1 for fixed b and n and variable k
- fkbnsieve: search for factors of the form k*bn+c for fixed k, b, and n and variable c
- gfndsieve: search for factors of k•2n+1, remaining terms are potential divisors of Generalized Fermat numbers
- kbbsieve: search for factors of numbers of the form k•bb+1 or k•bb-1 for fixed k and variable b
- xyyxsieve: search for factors of xy+yx and xy-yx
- gcwsieve: search for factors of Cullen primes and 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*(2p-1)+1 (potential divisors of Double Mersenne numbers)
- k1b2sieve: search for factors of the form 2n+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*bnn+c for fixed b and variable k and n
