About random number (random seed) in Msieve
Hello!
I have question about Block Lanczos algorithm (Montgomery) :
As i know during run Block Lanczos algorithm  we select random a matrix Y (size nxN, N = 64), therefore we use this matrix to run Block Lanczos algorithm. So i want to ask:
Can we know matrix Y that we initialized is best to run Block Lanczos algorithm? (I mean: if we use matrix Y, we always run Block Lanczos algorithm success.) And oppose, can we know matrix Y is bad to run Block Lanczos algorithm? (if we use bad matrix Y, Block Lanczos algorithm can fail!).
Thank for your reading.
