This is what I get for your poly with cownoise:

Code:

Looks good! I didn't try sopteffort, maybe I should.

I have an exceptional poly:

Code:

The same sizeoptimized poly gave 7 more polys above 1.2e-15.
My next best sizepotimized poly only yielded a 9.7e-16 poly.

swellman · 2020-11-28, 13:06

Wow, that’s an outstanding poly sir! Better than the record deg 6 for a C211. Congratulations!

Is further searching even warranted?

VBCurtis · 2020-11-28, 17:16

It's definitely warranted. Using a 4% guideline for poly select to expected sieve time, this ~120 core-year job should take ~5 core-years of poly select.

I don't know Gimarel's resources, but I cannot imagine Ed, Gimarel, and I have put even half a core-year into this yet; I've done about one core-month so far. If, after 3-4x more searching, we have no other candidates within 10% of this score then there's a case to be made that we found the One True Gem.

There are more needles in this haystack.

EdH · 2020-11-28, 19:05

I'm kind of just dabbling a bit currently. So, my search regions are minuscule and overlap others' though I might have slightly different parameters.

VBCurtis · 2020-11-29, 03:53

5-10M done. One poly similar to my previous results:

Cownoise: skew 140960.62565 score 8.85160007e-16

My resource is a GTX 2060 Super, running for about three days now. I've spend about 4.5 core-days for size-opt and root-sieve.

Thank you, EdH and swellman, for updating me on this poly cluster!
Congratulations, Gimarel, on such a good find! It looks exceptional compared to the chart data:

Code:

210_5  1.188e-15    vebis/spin	          05-19    2,2330M
210_6  1.491e-15    CADO team             05-18    RSA-210
211_5  1.007e-15    Gimarel/spin	  10-19    2,2210M
211_6  1.219e-15    VBCurtis              09-19    2,2210M

I'll see what I can do!

Gimarel, could you please post these 7 polys as well? Much appreciated in advance.
