Hi everybody,
Why did not the qmin parameter set to a much smaller value in all parameters files?
It is true that sieving in these intervals takes a longer time but on the other hand, it will find much more relations. Is this statement true that the found relations in the regions around 0 will be removed in the filtering?
One more question, In params.c120, it is mentioned that the BWC is about WN+CN^2 where W is weight, N is size of matrix and C is a constant 17.2 It seems this relation is a very helpful for finding the best values of max_level merging and target_density to have a good tradeoff between W and N. The question is whether C is 17.2 for all numbers? If not, how can I calculate it for other numbers such as RSA-512bit?
Thank you,
Elena
