So why don't you back up your claim? Here, let me give you a head start. Knuth does spend quite a bit of time on asymptotically fast matrix multiplication. Today we not only know methods that are asymptotically even faster, but we have a somewhat better understanding of *why* the methods work. That portion of that section is clearly out of date, albeit by only a few years. I can name a few other examples, each deserving an exercise or two and perhaps a mention in the text. None of them are important, the way that each new sorting algorithm has found its niche, or that the spectral test caught on, or that so many memory allocators depend on the buddy system. None of them could be discussed at Knuth's level for more than half a page. C'mon, Oz. You said the books are out of date by a decade and a half. That means that there have been discoveries throughout the last 15 years which, had they been known at the time, would have been included in the books. What are they? I'm perfectly willing to believe that they exist, but you have to prove it by example rather than rhetoric. ---Dan
