I will start spinning ahead of time and will do my absolute best to get you a very good poly. So far the best increase in E was 29%. I suspect it's not the limit yet.

Bur is learning what happens when toosmall parameter choices are made. I believe this job will finish, but it won't be pretty. You're correct to believe the remaining effort is less time than starting over, but now you know that a 20% complete job isn't so much sunk cost that starting over is out of the question.

I'm running a t35 on all of the unbooked composties in unhighlighted rows 158, 160, and 168172. This is good experience for avxecm.
So far (I will update as things progress): Code:
(10,5) c168 = p47*c123 (10,7) c282 = p26*c256 c288 = p11*c277 (5,10) c283 = p27*p32*p34*p35*c157 (4,10) c277 (#1) = p19*p17*p28*p34*c181 c277 (#2) = p22*p28*c229 (3,10) c265 = p14*prp251 (2,10) c231 = p24*c207 c249 = p15*p23*c212 (1,10) c184 = p36*c149 c235 = p28*prp207 Last fiddled with by bsquared on 20210614 at 17:35 Reason: more results

So lines 161 and 163 are free to take for ECM as well, if you wish. Last fiddled with by Max0526 on 20210614 at 17:10

If it's unique relations, then it's only missing 1.2e6 more, which is about 2e6 relations. I'm not sure if that estimate is correct anyway, since this is the 7th or so round of filtering. ETA is in 7 hours, so I'll know tomorrow morning.
VBCurtis, you're right, but is it certain the other parameters would have turned out better? They asked for 65e6 relations, which would be faster at the rels/q rate from testsieving but only if it wouldn't turn out to be an underestimation as well. Is there any way to prevent this underestimation of required relations from happening? Test filtering? Actually, it would be interesting to compeltely rerun this number using different parameters. Some other time though, currently the office is a sauna with the weather and the CPU. So I'll have to move the computer to an AC'ed room first as soon as this factorization finishes... ;) Last fiddled with by bur on 20210614 at 17:42

bur  watch that "excess" figure which pops up each time filtering runs; it was 1183116 in the log entry that you posted. That number should get smaller and smaller (in absolute value) until it turns positive, at which point filtering should succeed unless required_excess is nonzero. Keeping track of the excess will give you some idea of how much longer you'll need to sieve.

I've added a few more entries into factordb which are not currently on the Google Sheet. This is around the limit of numbers I can completely factor given the resources on my single Lenovo Ideapad 5 without causing performance issues for my other apps. General rule of thumb here is size of number ~ SNFS difficulty * 12.
