The GUI works on my Windows 8.1 machine, so that's good. I think it would be a nice addition for beginners if the GUI were bundled with the regular YAFU release.

Two quick suggestions: I believe...

I was actually considering making a GUI of YAFU myself, just for practice with Qt. I would like to see the original GUI, but the download for the .exe does not work for me.

Is it possible to resume progress of linear algebra? I had about 60% of it done and a nfs.dat.chk file, but running with -nc2 starts progress at 0% again.

It seems like all the steps, including -nc, finished correctly (end of -nc in screenshot), so I'm not sure what the problem is here. I guess I'll give my computer a break tonight.

Alright, I'm pretty sure the issue with the cycle file does not have to do with reading relations. Do you know how you usually get a cycle file?

I suggest you give it a go again. I've found YAFU 1.34 to be faster than when I last used factmsieve.py (last year). The renaming scheme appears to have worked so I will stick with that.

Wow, that is a nice visual! I would add rough composite size estimates (I believe ~100 digits for SIQS/GNFS crossover) but I don't know the crossover points for other methods.

I was just a few hours late...I did get a useful benchmark though. My factorization took somewhat longer than I expected - maybe it was because the two inputs were relatively unequal in size?
