I can ask min(f(x) = x), but I don't know how to tell it x restrictions.

I'm afraid this question will be closed as off-topic, but the WebApps beta might be the place to ask this – Tobias Kienzler Jul 27 '10 at 9:11
Can you move it there? – Semyon Perepelitsa Jul 27 '10 at 10:59
not yet, because the site is still in beta, we don't have this possibility yet. You will have to copy it yourself, for now, sorry about that. – Gnoupi Jul 27 '10 at 12:30
