- The antecedent of the pronoun "they" is unclear to me. To whom do
- you refer? And what is "it"? Derived the asymptotic run time? Or
- are you asking how the algorithm works?

- I gave a reference in the bibliography I just posted. The paper
- assumes quite a lot of background in algebraic number theory and
- knowledge of the quadratic sieve [they do not explain sieving
- procedures]. It also assumes you know a lot of general techniques
- in computational number theory, e.g. the Cantor-Zassenhaus method
- for factoring polynomials modulo primes, etc. etc. It is a really
- excellent paper, but novices will have a rough time with it.
