Appropriate for senior and graduate level courses in Computer Science Theory, Automata, and Theory of Computation. This is the long awaited Second Edition of Lewis and Papadimitriou's best-selling theory of computation text. In this substantially modified edition, the authors have enhanced the clarity of their presentation by making the material more accessible to a broader undergraduate audience with no special mathematical experience.

America's great research universities are the envy of the world—and none more so than Harvard. Never before has the competition for excellence been fiercer. But while striving to be unsurpassed in the quality of its faculty and students, Universities have forgotten that the fundamental purpose of undergraduate education is to turn young people into adults who will take responsibility for society. In Excellence Without a Soul , Harry Lewis, a Harvard professor for more than thirty years and Dean of Harvard College for eight, draws from his experience to explain how our great universities have abandoned their mission. Harvard is unique; it is the richest, oldest, most powerful university in America, and so it has set many standards, for better or worse. Lewis evaluates the failures of this grand institution—from the hot button issue of grade inflation to the recent controversy over Harvard's handling of date rape cases—and makes an impassioned argument for change. The loss of purpose in America's great colleges is not inconsequential. Harvard, Yale, Stanford—these places drive American education, on which so much of our future depends. It is time to ask whether they are doing the job we want them to do.

Using only practically useful techniques, this book teaches methods for organizing, reorganizing, exploring, and retrieving data in digital computers, and the mathematical analysis of those techniques. The authors present analyses that are relatively brief and non-technical but illuminate the important performance characteristics of the algorithms. Data Structures and Their Algorithms covers algorithms, not the expression of algorithms in the syntax of particular programming languages. The authors have adopted a pseudocode notation that is readily understandable to programmers but has a simple syntax.
