Thanks. This was the "more formal, but still readable" defintion of O() that I was looking for.

Also, BTW, while &Theta() is defined as the average-case, I think the normal-case is more often actualy used -- the average case can be impossible (or at least, impraticle) to compute. (Then again, I don't really know what I'm talking about.)
