ISBN o-201-06672-6 FGHIJ-HA-8987654 Preface This book is intended to survey the most important algorithms in use on computers today and to teach fundamental techniques to the growing number of people who are interested in becoming serious computer users. It is appropriate for use as a textbook for a second third or fourth course in computer science after students have acquired some programming skills and familiarity with computer systems but before they have specialized courses in advanced areas of computer science or computer applications. Additionally the book may be useful as a reference for those who already have some familiarity with the material since it contains a number of computer implementations of useful algorithms. The book consists of forty chapters which are grouped into seven major parts mathematical algorithms sorting searching string processing geometric algorithms graph algorithms and advanced topics. A major goal in the development of this book has been to bring together the fundamental methods from
