Writing Efficient Programs (Prentice-Hall Software Series)

Bentley has the right idea when he states that you first write a correct, understandable and maintainable program, and then if it is not fast enough, modify it to improve the efficiency. He is also correct in pointing out that with this approach, modifications to improve efficiency, while not altering the correctness of the program, tend to reduce the clarity and maintainability of the code. However, he does miss one important point, which in his defense, is to a large extent due to the date of original publication.With the availability of modern tools and advances in software design, it is now possible to create programs where the efficiency of the code can be part of the design. Changes in the design made to improve the efficiency can increase the maintainability and reduces the need for final alterations that lower the clarity and portability. Classic on practical methods of optimizing programs: This book gives practical advice on improving the efficiency (optimizing) programs and the limits there of. While showing how to trade off speed for space or vice-versa, the author points out the limits that can be expected to gain. His list of techniques is a collection of practical approaches rather than theoretical possibilities. At 158 pages (not counting index) this book is eminently readable, accessable and useful. Clearly written and well organized this is a book to keep on your shelf for when a program needs improving. It is also a book to read before a program as a reminder not to make things complicated with optimization that aren't needed WRITING EFFICIENT PROGRAMS JON LOUIS BENTLEY The photo is the actual copy you are bidding on and it is shipped bagged and boarded for its protection.
