Currently I'm reading some few papers, sometimes I think something is wrong or I can't understand it, So I'll ask it in CSTheory, but simple comment helps me to find out my problem, after that I'll remove my question (and upvote commenter in another answer).
Currently I think I'm like spam generator, but really I can't ask this question in another sites (like math,stackoverflow,...) because they need good knowledge in field (they are easy to answer with this knowledge but without this knowledge they aren't readable).
I don't know is there any other option (like chat, but all user can see it)? Or I shouldn't do so?
