Optimization and selection of the top scoring polynomial from a larger set

[Plutie]

Looks good! Considering the intended purpose of my script, knowing that its end result is in some cases the same as yours is a good sign, even though it's probably just due to the high sopt/ropteffort settings I use.

This version (1.0.1) ran fine for me with the original input poly from earlier:

I was recently reminded of your efforts in this thread from last year, when I started another similar one:

https://www.mersenneforum.org/showthread.php?t=28097

This is slightly different from your efforts, but may be close enough for ideas to be passed between. Where have you gotten with your scripts?
