"going from an algorithm with O(n^2) performance to one with O(n^lg^n) performance" could anyone explain what O(n^2) and O(n^lg^n) means, preferably in a very simple down to earth way please? i've seen O(n^2), or something very similar, in many things i've read and never known what it means. any explenation much appreciated. xtra question: anyone know of any good powerpc assembly books / tutorials? thanks.
