..."In essence, an algorithm’s computational complexity is a measure of how the time and/or space it requires to execute grows with the size of the representation of its input."..."when looked at from a slightly different perspective, the entire body of computational complexity research is really a study of how algorithms consume energy and, hence, could serve as a source of guidance for application level energy management."
