I’m still working on my range but I’m playing around a bit in a vain attempt to tune/optimize CADO poly searching a c204. Learning something if nothing else, but collecting data as I go.

Thank you for summarizing the issue so well. I’m varying ropteffort and nrkeep with the c204 poly search just to get a feel for the resulting poly score and runtime.

I will attempt 6e7 to 7e7 with P = 4M. May also attempt P values of 8M and 14M if my hardware can handle that search space in a reasonable time.

I’ve struggled with this parameter - why hang on to hundreds of likely subpar polys that seemingly take forever to complete root-opt, instead just keep the “cream of crop”. But then if one cuts...

C191

No worries Ed - I am using msieve-GPU and there’s no real chance of overlap between the two of us.

You’ve already beaten the best poly for a C192, so finding anything better going forward is gravy.

C191

My best poly found so far is 1.54e-14, which is far from spectacular so I didn’t post it (though I did save it locally).

Nice. I’ll keep an eye on NFS@Home job for this composite, though it probably won’t finish sieving until midsummer. But ~100M relations added onto what 15e generates should get this onto LA.
