A script which implements the lattice basis reduction
methods of Coppersmith and Howgrave-Graham to search for
divisors in residue classes. This is useful when a BLS test
with a factorization percentage of more than 25% has been
run. The script is available at the primeform
e-mail group , under "CHG.GP."
Factorization percentage record: 26.14% by Broadhurst,
Renze, and de Water (December 2005)
