Two different P-1 types of work in worktodo.ini

eepiccolo · 2003-04-30, 14:37

I was looking at readme.txt and undoc.txt, and noticed something about P-1 work. In readme.txt, it lists adding P-1 work using Pminus1=. But in undoc.txt, it lists adding P-1 work using Pfactor=. What is the difference between these two?

Pminus1= comes from using Advanced/P-1 menu choice. It lets you pick any B1 and B2 values you want.

Pfactor= can be used to do the P-1 factoring that normally preceeds a double-check or first-time test. In this case Prime95 picks the best B1 and B2 values based on available memory, chance of finding a factor, and expected LL test time saved. This work type can only happen by editing your worktodo.ini file. This is what will appear in your worktodo.ini file if P-1 factoring ever becomes a separate work type.
