I can clear this up, at least a bit, since I was there. (Although I can’t say that I clearly remember every detail.) All the writing on the problem page is definitely Leo’s, and, yes, he wrote the misspelled “NP Complete”, and did (does) know what it means, at least in the sense of a problem that has an easy to check solution, but for which you have to try every possible combination to find them. As for Snuffycode, the writing is obviously mine, and the language is obviously nonsense. (I guess he wrote out the template.) I think that what was happening is that we were talking through an algorithm using a binary selection mechanism (APL-Like, as mentioned). As with the Lisp, I was “typing” but we were talking it through collaboratively. At least that’s my recollection.
