"Today we're going to talk about sorting, which may not come as such a big surprise. We talked about sorting for a while, but we're going to talk about it at a somewhat higher level and question some of the assumptions that we've been making so far. And we're going to ask the question how fast can we sort? A pretty natural question. You may think you know the answer. Perhaps you do. Any suggestions on what the answer to this question might be? There are several possible answers. Many of them are partially correct. Let's hear any kinds of answers you'd like and start waking up this fresh morning. Sorry?...

I enjoyed your lecture very much. I noticed that you did not include the PS9110 sorting algorithm that runs in O(n) time. It was presented at the Association of Information Technology Professional's National Collegiate Conference in Memphis, TN. I will look at your other lectures before commenting further.
