-npr is now running on the best candidates from the range of leading coeff 60M to 60.9M.

Code:

skew 1893745.33, size 1.561e-016, alpha -6.434, combined = 3.707e-013 rroots = 5

Maybe I can find a better one. Let me know if I should stop.

I can wait for as long as it takes. Not on any timetable.

Thanks again.

OK, I'll give it some more effort then.

What norm did the rest of you use for -npr?

Posting this one because of the crazy alpha-value;

Code:

I use the default norms for -npr. I set a bound on the e-value just to keep output brief- that does not alter the polys found.

I did set stage2norm of 3.5e22 while doing -nps, and then ran -npr on the entire output.
-Curtis

wombatman · 2013-08-23, 20:10

I normally reduce the stage 2 norm by one order of magnitude from the default choice and pull the top 100 or 200 (usually 200) results from -nps with sort -g -k 10 file.ms | head -200 > newfile.ms. Then I'll run -npr, using a minimum e-value if I already have something and am only looking to better it.

I've just started the polynomial search for 3,766+. Any help you wish to provide would be appreciated.

Just to set a baseline, here's the best so far:

edit :oops, C6.. nevermind

wombatman · 2013-08-27, 13:25

I'll start at 10M and work toward 12M or so on 3,766+.

Edit: Or at least I will once I figure out how to get msieve to work on numbers > 311 digits...

firejuggler · 2013-08-27, 13:37

hmm? get to factordb, type 3^766+1; find the C216...
and don't forget to add "polydegree=6" in your parameters

Code:

wombatman · 2013-08-27, 14:41

I should have known it was a smaller composite. My bad. I'll start my run tonight.

VBCurtis · 2013-08-28, 05:58

I estimate 7-10 GPU-months to find a poly for this? wowsers.

I'll give it a GPU-week or two, after the heat in the IE subsides a little.
