No, these are different.

Sometimes a poly with a lower norm has a better score, but most of the time this is correct.

I don't know how the exp_E in CADO is computed.

One step of the spinning script is to invert the signs of the algebraic side. I run the rootsieve for both, the original poly and the poly with inverted signs on the algebraic side. Sometimes this...

I missed that post, sorry.
I think, that the "from original" is way off.

Currently I don't know a way how to tell unmodified msieve to output the norm of the sopt-optimized poly. And if you want to rootsieve say 1000 polys, then you have to make at least 6000 starts of...

I use a starting value relative to the msieve computed stage2_norm of the poly. To do this I modified msieve :smile:.

Sure. The real question is how many ore up to what exp_E. But I can't answer this as I'm still experimenting.

The stage 1 of CADO has two parameters, the number of special-q and the [P,2P] interval. msieve translates the stage1_norm to something similar, a special-q range and "other". If you increase...

No, you want to run all stage 1 hits through sopt. This is the reason to use a very high stage2_norm so msieve doesn't omit some hits.

If the order doesn't matter this is shorter:
