I'm happy to announce Volume 1, Number 1 of a new journal, ACM Transactions on Algorithms (July 2005), edited by the entire former editorial staff of the Journal of Algorithms. It's available now at ACM's Digital Library. Last year the editor-in-chief (Hal Gabow of the University of Colorado) promised that the inaugural issue would be ``gangbusters''; his promise was, if anything, an understatement. Congratulations to all the authors and editors!
David Kestenbaum came to Stanford in July 2004 and spent an entire day following me around; we even went swimming together! He taped a lot of noises that I made, and eventually boiled everything down to an 8-minute interview that aired on Morning Edition on 14 March 2005. (Great job, David, making sense out of my nerdy life. Of course you meant to say ``100 million'' instead of ``10 million'' at one point:-)
Hurray, hurray: After many years of preparation, at last I can report the publication of new material for my books on The Art of Computer Programming, first released in paperback on Valentine's Day of this year. ``Volume 1 Fascicle 1,'' a programmer's introduction to the MMIX computer, is an update to Sections 1.3 and 1.4 of Volume 1, Fundamental Algorithms, planned for inclusion in the eventual fourth edition of that volume. ``Volume 4 Fascicle 2'' contains sections 7.2.1.1 and 7.2.1.2 of Volume 4, Combinatorial Algorithms, a work in progress. ``Volume 4 Fascicle 3,'' published in August, contains sections 7.2.1.3--7.2.1.5 of Volume 4. The publishers plan to release Volume 4 Fascicle 4 next winter, Volume 4 Fascicle 1 next summer, and approximately two fascicles per year henceforth.
First drafts of some of the forthcoming fascicles are also ready for beta-testing. I've put them online primarily so that experts in the field can help me check the results; but brave souls who aren't afraid to look at relatively raw copy are welcome to look too. (Yes, the usual rewards apply if you find any mistakes.)
(If you have trouble downloading these files, your browser is probably screwing up; please see my FAQ page for a workaround.)
Note to Internet friends: I'm extremely grateful that hundreds of you have taken time to read these drafts, and to detect and report errors that you've found. Your comments have improved the material enormously. But I must confess that I'm also disappointed to have had absolutely no feedback so far on several of the exercises on which I worked hardest when I was preparing this material. Could it be that (1) you've said nothing about them because I somehow managed to get the details perfect? Or is it that (2) you shy away from the more difficult stuff, being unable to spend more than a few minutes on any particular topic? Although I do not like to think that readers are lazy, I fear that hypothesis (1) is far less likely than hypothesis (2). I may have to remove material that nobody cares about. But I still cling to a belief that this stuff is extremely instructive. Thus I would like to enter here a plea for some readers to tell me explicitly, ``Dear Don, I have read exercise N and its answer very carefully, and I believe that it is 100% correct,'' where N is one of the following:
Note that you don't have to work the exercise first; you're allowed and even encouraged to peek at the answer. Please send success reports to the usual address for bug reports (taocp@cs.stanford.edu), if you have time to provide this extra help. Thanks in advance!
During our summer vacation in 2003, my wife and I amused ourselves by taking leisurely drives in Ohio and photographing every diamond-shaped highway sign that we saw along the roadsides. (Well, not every sign; only the distinct ones.) For provenance, I also stood at the base of each sign and measured its GPS coordinates.
This turned out to be even more fun than a scavenger hunt, so we filled in some gaps when we returned to California. And we intend to keep adding to this collection as we drive further, although we realize that we may have to venture to New England in order to see `FROST HEAVES'.
Here are the images of our collection so far.
Videotapes of most of my Computer Musings have been made since 1998, and I have often loaned copies to people who were unable to attend in person.
Now there is good news and bad news. The good news is that more than a dozen of these videos have been digitized, and they are available for viewing. The bad news is that three people have not returned the tapes they borrowed, and there is no backup copy; I learned recently that my copy was unique, because all the master tapes were erased. If you are the person who currently has any of the following tapes:
please PLEASE return it/them immediately.
Although I must stay home most of the time and work on books that I've promised to complete, I do occasionally get into speaking mode. Here is a current schedule of events that have been planned for this year so far:
