Allow me to lend a hand.

Well, not really- it's likely Ryan wouldn't pay attention or have a go at it until something near t55 was done.

If you don't want to use the Bayesian tool each time you queue curves, you can still improve on the old methods by doing half the usual number of curves at a B1 level before moving to the next B1. Once you've done half a t50, move to B1 = 110M, etc. The second half of the effort for t50 is then completed by the 110M-bound curves,while improving chances to find bigger factors.

I were running all curves up to B1=110e6 for the current C167.
More curves required?

~2*t50 is enough for C167, so t55 is more than enough.

С167 splits as P81*P87, next blocker is C157, ECM'ed to t40 by me.

I'll help out here:

Curtis, seems that 4788 is waiting on a C146 that showed up a few lines and a few days after the most recent post here, do you want to CADOize it?

VBCurtis · 2017-12-12, 17:22

Yes, please! I'll start this morning. Should be 4 days or so.

4 days for a c146. <===> 4000 days for a c197.
(Just to keep things in perspective.)

Ye assume he has nothing in his Q.
