R337/c202
 
I tested the exceptionally good files.
The cpu-times are close to each other.
The poly-file from post 1931 (Gimarel/Max: skew: 50335474.00; size 8.799e-20; alpha -8.773, combined = 3.886e-15 ...)
clearly gives the most yields/1q.

parms: 16e; .lim ~ 450M; q-range: 50M - 425M; lpb. 33/33
target: 1050M r.rels; ~ 740M unique rels; matrix 45M - 49M;
Many thanks for the valuable preparatory work

Greetings,

Any help that folks can provide in finding a poly for the C175 of of Aliquot sequence 829332 i3694 would be greatly appreciated. The composite has been ecm'ed to t55.

[CODE]9536454284838131188510297375465325383144598450008668632355935685754692107419202674411506591342057862756227100567184249373517764331520778025660438418594966383559123819525015791[/CODE]

I am running a CPU poly search on this number for coefficients up to 1,500 using msieve through YAFU, and my intention is to use NFS@Home for sieving once a suitable poly is found.

Thanks very much!

Thank you, unconnected, for sharing!
And still too low to compete with the current (August 2020) C183 record of charybdis (6.382e-14).
Will re-run through CADO, it might get better.

That’s not a poly, that’s a work of art. Holy e-score Batman!

I’m continuing to search but...

VBCurtis 2021-01-11 23:00

Beats the record by 15%, again. That's a full digit of difficulty. Nice!

Rather than try to beat that result, a quick msieve search for the C191 suddenly available in the Cunningham Project subforum would be nice. I think Charybdis and I plan to finish poly select Tuesday night, with sieving starting Wednesday. Any efforts there are appreciated.

I’m done searching. Will post Gimarel’s record poly score in a day or two unless someone else informs me they are hunting polys.
