Definition: An asymptotic bound, as function of the size of the input, on the best (fastest, least amount of space used, etc.) an algorithm can possibly achieve to solve a problem. That is, no algorithm can use fewer resources than the bound.
See also Ω, asymptotic upper bound, asymptotically tight bound.
