Cutland's Computability: An Introduction to Recursive Function Theory (Cambridge)[edit]

  • Cutland, Nigel J. (1980). Computability: An Introduction to Recursive Function Theory. Cambridge University Press. ISBN 978-0-521-29465-2.

The review of this early text by Carl Smith of Purdue University (in the Society for Industrial and Applied Mathematics Reviews),[1] reports that this a text with an "appropriate blend of intuition and rigor… in the exposition of proofs" that presents "the fundamental results of classical recursion theory [RT]... in a style... accessible to undergraduates with minimal mathematical background". While he states that it "would make an excellent introductory text for an introductory course in [RT] for mathematics students", he suggests that an "instructor must be prepared to substantially augment the material… " when it is used with computer science students (given a dearth of material on RT applications to this area).[1]

Decidability of second order theories and automata on infinite trees[edit]

Description: The paper presented the tree automaton, an extension of the automata. The tree automaton had numerous applications to proofs of correctness of programs.

Finite automata and their decision problems[edit]

On computable numbers, with an application to the Entscheidungsproblem[edit]

Description: This article set the limits of computer science. It defined the Turing Machine, a model for all computations. On the other hand, it proved the undecidability of the halting problem and Entscheidungsproblem and by doing so found the limits of possible computation.

Representation of Events in Nerve Nets and Finite Automata[edit]

Description: this paper introduced finite automata, regular expressions, and regular languages, and established their connection.

Computational complexity theory[edit]

Arora & Barak's Computational Complexity and Goldreich's Computational Complexity (both Cambridge)[edit]

  • Sanjeev Arora and Boaz Barak, "Computational Complexity: A Modern Approach," Cambridge University Press, 2009, 579 pages, Hardcover
  • Oded Goldreich, "Computational Complexity: A Conceptual Perspective, Cambridge University Press, 2008, 606 pages, Hardcover

Besides the estimable press bringing these recent texts forward, they are very positively reviewed in ACM's SIGACT News by Daniel Apon of the University of Arkansas,[4] who identifies them as "textbooks for a course in complexity theory, aimed at early graduate… or... advanced undergraduate students… [with] numerous, unique strengths and very few weaknesses," and states that both are:

"excellent texts that thoroughly cover both the breadth and depth of computational complexity theory… [by] authors... each [who] are giants in theory of computing [where each will be] exceptional reference text for experts in the field… [and that] ...theorists, researchers and instructors of any school of thought will find either book useful."

The reviewer notes that there is "a definite attempt in [Arora and Barak] to include very up-to-date material, while Goldreich focuses more on developing a contextual and historical foundation for each concept presented," and that he "applaud[s] all… authors for their outstanding contributions."[4]

A machine-independent theory of the complexity of recursive functions[edit]

Note that similar ideas were developed independently slightly later by Leonid Levin at "Levin, Universal Search Problems. Problemy Peredachi Informatsii 9(3):265–266, 1973".

Computers and Intractability: A Guide to the Theory of NP-Completeness[edit]

Description: The main importance of this book is due to its extensive list of more than 300 NP-Complete problems. This list became a common reference and definition. Though the book was published only few years after the concept was defined such an extensive list was found.

Degree of difficulty of computing a function and a partial ordering of recursive sets[edit]

"A polynomial algorithm in linear programming"[edit]

Description: For long, there was no provably polynomial time algorithm for the linear programming problem. Khachiyan was the first to provide an algorithm that was polynomial (and not just was fast enough most of the time as previous algorithms).

The Art of Computer Programming[edit]

Description: This monograph has four volumes covering popular algorithms. The algorithms are written in both English and MIX assembly language (or MMIX assembly language in more recent fascicles). This makes algorithms both understandable and precise. However, the use of a low-level programming language frustrates some programmers more familiar with modern structured programming languages.

Algorithms + Data Structures = Programs[edit]

Description: An early, influential book on algorithms and data structures, with implementations in Pascal.

The Design and Analysis of Computer Algorithms[edit]

Formal verification[edit]

Assigning Meaning to Programs[edit]

Description: Robert Floyd's landmark paper Assigning Meanings to Programs introduces the method of inductive assertions and describes how a program annotated with first-order assertions may be shown to satisfy a pre- and post-condition specification – the paper also introduces the concepts of loop invariant and verification condition.

An Axiomatic Basis for Computer Programming[edit]

Description: Tony Hoare's paper An Axiomatic Basis for Computer Programming describes a set of inference (i.e. formal proof) rules for fragments of an Algol-like programming language described in terms of (what are now called) Hoare-triples.

Guarded Commands, Nondeterminacy and Formal Derivation of Programs[edit]

Description: Edsger Dijkstra's paper Guarded Commands, Nondeterminacy and Formal Derivation of Programs (expanded by his 1976 postgraduate-level textbook A Discipline of Programming) proposes that, instead of formally verifying a program after it has been written (i.e. post facto), programs and their formal proofs should be developed hand-in-hand (using predicate transformers to progressively refine weakest pre-conditions), a method known as program (or formal) refinement (or derivation), or sometimes "correctness-by-construction".

Proving Assertions about Parallel Programs[edit]

Description: The paper that introduced invariance proofs of concurrent programs.

An Axiomatic Proof Technique for Parallel Programs I[edit]

Description: In this paper, along with the same authors paper "Verifying Properties of Parallel Programs: An Axiomatic Approach. Commun. ACM 19(5): 279–285 (1976)", the axiomatic approach to parallel programs verification was presented.

A Discipline of Programming[edit]

Description: Edsger Dijkstra's classic postgraduate-level textbook A Discipline of Programming extends his earlier paper Guarded Commands, Nondeterminacy and Formal Derivation of Programs and firmly establishes the principle of formally deriving programs (and their proofs) from their specification.

Description: The use of temporal logic was suggested as a method for formal verification.

Characterizing correctness properties of parallel programs using fixpoints (1980)[edit]

Description: Model checking was introduced as a procedure to check correctness of concurrent programs.

Communicating Sequential Processes (1978)[edit]

Description: Tony Hoare's (original) communicating sequential processes (CSP) paper introduces the idea of concurrent processes (i.e. programs) that do not share variables but instead cooperate solely by exchanging synchronous messages.

A Calculus of Communicating Systems[edit]

Description: Robin Milner's A Calculus of Communicating Systems (CCS) paper describes a process algebra permitting systems of concurrent processes to be reasoned about formally, something that has not been possible for earlier models of concurrency (semaphores, critical sections, original CSP).

Software Development: A Rigorous Approach[edit]

Description: Cliff Jones' textbook Software Development: A Rigorous Approach is the first full-length exposition of the Vienna Development Method (VDM), which had evolved (principally) at IBM's Vienna research lab over the previous decade and which combines the idea of program refinement as per Dijkstra with that of data refinement (or reification) whereby algebraically defined abstract data types are formally transformed into progressively more "concrete" representations.

The Science of Programming[edit]

Description: David Gries' textbook The Science of Programming describes Dijkstra's weakest precondition method of formal program derivation, except in a very much more accessible manner than Dijkstra's earlier A Discipline of Programming.

It shows how to construct programs that work correctly (without bugs, other than from typing errors). It does this by showing how to use precondition and postcondition predicate expressions and program proving techniques to guide the way programs are created.

The examples in the book are all small-scale, and clearly academic (as opposed to real-world). They emphasize basic algorithms, such as sorting and merging, and string manipulation. Subroutines (functions) are included, but object-oriented and functional programming environments are not addressed.

Communicating Sequential Processes (1985)[edit]

Description: Tony Hoare's Communicating Sequential Processes (CSP) textbook (currently the third most cited computer science reference of all time) presents an updated CSP model in which cooperating processes do not even have program variables and which, like CCS, permits systems of processes to be reasoned about formally.

Linear logic (1987)[edit]

Description: Girard's linear logic was a breakthrough in designing typing systems for sequential and concurrent computation, especially for resource conscious typing systems.

A Calculus of Mobile Processes (1989)[edit]

Description: This paper introduces the Pi-Calculus, a generalisation of CCS that allows process mobility. The calculus is extremely simple and has become the dominant paradigm in the theoretical study of programming languages, typing systems and program logics.

The Z Notation: A Reference Manual[edit]

Description: Mike Spivey's classic textbook The Z Notation: A Reference Manual summarises the formal specification language Z notation, which, although originated by Jean-Raymond Abrial, had evolved (principally) at Oxford University over the previous decade.

Communication and Concurrency[edit]

Description: Robin Milner's textbook Communication and Concurrency is a more accessible, although still technically advanced, exposition of his earlier CCS work.

a Practical Theory of Programming[edit]

Description: the up-to-date version of Predicative programming. The basis for C.A.R. Hoare's UTP. The simplest and most comprehensive formal methods.
