# What does “Quick” mean?

What does quick/fast mean in the context of computer science?

I couldn't find a definition online (poor google fu), and I want to provide a referenced/cited definition for fast for an article I'm writing.

And, just like the driving example, what would be considered "quick" depends on context. If you gave me a $\Theta(n^3)$ algorithm for graph isomorphism, I'd bite your hand off; if you gave me a $\Theta(n^3)$ algorithm for sorting, I'd think you were an idiot.
