For some kolmo questions, I use the golfing algorithms created for the challenge Golfing Strings in Fourier.
Is this okay to do? Does this constitute as cheating?
I don't think these answers are cheating, exactly. I don't believe they break any current site rules.
That being said, I'll probably downvote them when I see them. They're just not interesting or useful to the site in my opinion. The program that generates it might be interesting (and indeed, I upvoted issacg's program when he posted it), but I don't think that extends to the output itself.
Of course, this applies to the straight "copy/paste" answers. If all you did was copy the desired output into a script and paste the output as an answer, I don't want to reward that with rep. If you're manually golfing it before or after running the script and making tweaks to optimize it, that's a different story. If that's the case, say that in the post.
