Running as I type....def-par.txt says "good score" = 2.36e-11, so you're already above that.

EDIT - I might have to lower the score on this one. It's spending <1 minute per range of 1000 and it's at 108000 for the leading coeff and hasn't found a single one....

2.36e11 is a cut off point, not necessarily a "good" score.
I started at 5000 and best so far is 2.62e-011

Frank, can you merge the poly search details into the newly created sieve thread?

I realize that. This was the first time that I've seen a search go as high as it did and find *nothing*. I was thinking of lowering the score to see if it could find *anytthing*. For most of my searches, something usually turns up immediately that is very close to the "good score". The above poly is the second to turn up; the first was 2.94e-11, which is considerably higher than I normally see as a first effort.....


Next question is, do we need to do more ECM, or do we call it good?

That's excellent. Once I get back home, I'll check is msieve has something better for us ;-)

Sure thing.....I don't know if it's quite what you expected, though.....

Or we could do it this way....

I didn't find anything better than 2.81

I did some limited testing with the above poly:

14e sp 12M, lpb 28 	total yield: 4325, q=10001009 (0.05886 sec/rel)
13e sp 12M, lpb 28	total yield: 2030, q=10001009 (0.04753 sec/rel)
14e sp 12M, lpb 27	total yield: 2131, q=10001009 (0.11947 sec/rel)
13e sp 12M, lpb 27	total yield: 1001, q=10001009 (0.09609 sec/rel)

13e sp 10M, lpb 28	total yield: 2000, q=10001009 (0.04623 sec/rel)
13e sp 16M, lpb 28	total yield: 2074, q=10001009 (0.05032 sec/rel)
