Data Structures and Algorithms by Alfred V. AhoYou might think, in a field like computer science a book from the 1980s might be useless, because development in computer science is progressing so fast. But thats not true. The basics, like data structures and algorithms, have been established from the 50s to 70s, and I found few difference between the topics discussed in this data structures book on the one hand and two more recent books that Ive read on the topic. Having found that directed graphs are still directed graphs, b-trees are still b-trees, and quicksort is still quick, the age of an introductory book to algorithms obviously doesnt matter so much. Then what matters more is the way its presenting and explaining things, the overall didactic structure. And from this point of view I found this edition here the most accessible introduction. The images are usually illuminating, the text is easily understandable. Some math formulas could be a little bit ominous, but thats the case to me in all those books on the topic that Ive touched so far. Another little disadvantage that comes with the age is that all the programming code examples are given in Pascal. But even that is a manageable disadvantage: Even without any active proficiency in that outdated language, the examples are still readable and understandable to people with experience in Java or a newer programming idiom.

The basis of this book is the material contained in the first six chapters of our earlier work, The Design and Analysis of Computer Algorithms. We have expanded that coverage and have added material on algorithms for external storage and memory management. As a consequence, this book should be suitable as a text for a first course on data structures and algorithms. The only prerequisite we assume is familiarity with some high-level programming language such as Pascal. We have attempted to cover data structures and algorithms in the broader context of solving problems using computers. We use abstract data types informally in the description and implementation of algorithms.
