This is the seventh in a series of eight volumes that contain archival forms of my published papers, together with new material. (The first book in the series was Literate Programming; the second was Selected Papers on Computer Science; the third was Digital Typography; the fourth was Selected Papers on Analysis of Algorithms; the fifth was Selected Papers on Computer Languages; the sixth was Selected Papers on Discrete Mathematics.) The Design of Algorithms volume is characterized by the following remarks quoted from its preface.
Algorithms are the threads that tie together most of the subfields of computer science. This book is a collection of technical papers in which I've tried to introduce or make improvements to algorithms for a wide variety of intriguing tasks that have come to my attention during the past fifty years. I'm grateful for this opportunity to put the materials into a consistent format, and to correct errors in the original publications that have come to my attention. If any of this work deserves to be remembered, it is now in the form that I most wish people to remember it.
Something magically beautiful happens when a sequence of commands and decisions is able to marshal a collection of data into organized patterns or to discover hidden structure. Every once in awhile something ``clicks''; an elegant procedure suddenly emerges by which small steps combine to fulfill a large objectiveaha! On several occasions I've been lucky enough to encounter some of these unexpected nuggets of algorithmic paydirt, and I hope that I can communicate the essence of what makes them tick so that readers will be able to share my pleasure.
Since many different kinds of algorithms are considered here, I've organized this book by topic instead of by chronology. I doubt if anybody will actually read this book straight through from Chapter 1 to Chapter 28; yet I've tried to arrange the chapters so that such a journey will not seem like a completely random walk. Algorithms that deal with similar topics or use similar paradigms are therefore grouped together.
Chapter 1, however, is not about any particular algorithm. It is a eulogy to Bob Floyd, my longtime colleague to whom this book is dedicated, because he helped significantly to inspire so many of the ideas that are described in the other chapters. I know of no better way to begin a book about the design of algorithms than to describe Floyd's life and work.
... And then the preface continues by describing the other chapters, which can be summarized more succinctly by quoting from the hype on the back cover:
Nearly thirty of Knuth's classic papers on the subject are collected in this book, brought up to date with extensive revisions and notes on subsequent developments. Many of these algorithms have seen wide use  for example, Knuth's algorithm for optimum search trees, the FallerGallagerKnuth algorithm for adaptive Huffman coding, the KnuthMorrisPratt algorithm for pattern matching, the DijkstraKnuth algorithm for optimum expressions, and the KnuthBendix algorithm for deducing the consequences of axioms. Others are pedagogically important, helping students to learn how to design new algorithms for new tasks. One or two are significant historically, as they show how things were done in computing's early days. All are found here, together with more than 40 newly created illustrations.
Here's the table of contents:
(Numbers like P85 and Q17 in this list refer to the corresponding papers in my list of publications.)
Selected Papers on Design of Algorithms bears Knuth's usual eloquence in writing. The algorithms and proofs in each chapter are presented cleanly, and pseudocode for implementing them accompanies most of the algorithms. Part of the real charm of this collection comes from the historical notes interspersed throughout the book. These take the form of either additional commentary attached to the end of a paper ... explaining which open problems have been solved, which haven't, and how the newer results were obtained ... Gems like these are probably the best reason to own the book.

This book can be ordered from the publisher (CSLI), and also from the distributor (University of Chicago Press).
As usual, I promise to deposit 0x$1.00 ($2.56) to the account of the first person who finds and reports anything that remains technically, historically, typographically, or politically incorrect.
Here is a list of all nits that have been picked so far in the first printing (2010); an asterisk (*) marks technical errors that are not merely typographical:
 page xiv, line 8 from the bottom (05 February 2011)
 change "Edsger" to "Edsger W."
 page 14, line 6 (01 June 2010)
 change "Catholic University" to "Pontifical Catholic University"
 page 71, lines 5 and 6 (30 April 2010)
 "A. V. Anisimov ... Programmirovanie" should be in a slanted Cyrillic font

 "Trudy ... Steklova" should be in a slanted Cyrillic font
 page 136, new paragraph (27 June 2012)
 I learned in 2012 that Yuri Matiyasevich had anticipated the lineartime pattern matching and pattern preprocessing algorithms of this paper, in the special case of a binary alphabet, already in 1969. He presented them as constructions for a Turing machine with a twodimensional working memory in the paper ``Realtime recognition of the inclusion relation,'' Journal of Soviet Mathematices 1 (1973), 6470, which is a translation of his original Russian article in Zapiski Nauchnykh Seminarov Leningradskogo Otdeleniya Matematicheskogo Instituta imeni V. A. Steklova 20 (1971), 104114.

 Egon Balas, Matteo Fischetti, and Arrigo Zanette [``A hard integer program made easy by lexicography,'' Mathematical Programming A135 (2012), 509514] have used dramatically improved integer programming techniques to show that the optimum cost remains 22996 when this correction is made.

I hope the book is otherwise errorfree; but (sigh) it probably isn't, because each page presented me with hundreds of opportunities to make mistakes. Please send suggested corrections to knuthbug@cs.stanford.edu, or send snail mail to Prof. D. Knuth, Computer Science Department, Gates Building 4B, Stanford University, Stanford, CA 943059045 USA. In either case please include your postal address, so that I can mail an official certificate of deposit as a token of thanks for any improvements to which you have contributed.
I may not be able to read your message until many months have gone by, because I'm working intensively on The Art of Computer Programming. However, I promise to reply in due time.
DO NOT SEND EMAIL TO KNUTHBUG EXCEPT TO REPORT ERRORS IN BOOKS! And if you do report an error via email, please do not include attachments of any kind; your message should be readable on brandX operating systems for all values of X.
