First account of the subject by two of its leading exponents. Essentially self-contained.

This book constitutes the thoroughly refereed post-workshop proceedings of the 11th International Workshop on the Implementation of Functional Languages, IFL'99, held in Lochem, The Netherlands, in September 1999. The 11 revised full papers presented were carefully selected during two rounds of reviewing. The papers are organized in sections on applications, compilation techniques, language concepts, and parallelism.

The International Workshops on the Implementation of Functional Languages (IFL)havebeenrunningfor14yearsnow.Theaimoftheseworkshopsistobring together researchers actively engaged in the implementation and application of functional programming languages to discuss new results and new directions of research. A non-exhaustive list of topics includes: language concepts, type che- ing, compilation techniques, (abstract) interpretation, automatic program g- eration, (abstract) machine architectures, array processing, concurrent/parallel programming and program execution, heap management, runtime pro?ling and performance measurements, debugging and tracing, veri?cation of functional programs, tools and programming techniques. The 14th edition, IFL 2002, was held in Madrid, Spain in September 2002. It attracted47researchersfromthefunctionalprogrammingcommunity,belonging to10di?erentcountries.Duringthethreedaysoftheworkshop,34contributions were presented, covering most of the topics mentioned above. The workshop was sponsored by several Spanish public institutions: the M- istry of Science and Technology, Universidad Complutense de Madrid, and the Tourism O?ce, Town Hall and Province Council of Segovia, a small Roman and medieval city near Madrid. We thank our sponsors for their generous contri- tions. This volume follows the lead of the last six IFL workshops in publishing a high-quality subset of the contributions presented at the workshop in Springer’s Lecture Notes in Computer Science series. All speakers attending the workshop were invited to submit a revised version for publication. A total of 25 papers were submitted. Each one was reviewed by four PC members and thoroughly discussed by the PC. The results of this process are the 15 papers included in this volume.

Describes different ways of implementing functional programming languages which bear a strong family resemblance to one another, and which all have their origins in the work of Turner on combinator-based graph-reducers. First chapters cover translation of Lipskit into combinatory logic, and evaluation of the resulting object code by graph-reduction. Later chapters follow a natural progression, refining and improving the efficiency of this implementation.

The 16th International Workshop on Implementation and Application of Fu- tional Languages (IFL 2004) was held in Lub ̈ eck, Germany, September 8–10, 2004. It was jointly organized by the Institute of Computer Science and Applied Mathematics of the University of Kiel and the Institute of Software Technology and Programming Languages of the University of Lub ̈ eck. IFL 2004 was the sixteenth event in the annual series of IFL workshops. The aim of the workshop series is to bring together researchers actively engaged in the implementation and application of functional and function-based progr- ming languages. It provides an open forum for researchers who wish to present and discuss new ideas and concepts, work in progress, preliminary results, etc., related primarily, but not exclusively, to the implementation and application of functional languages. Topics of interest cover a wide range from theoretical - pects over language design and implementation towards applications and tool support. Previous IFL workshops were held in the United Kingdom (Southampton, Norwich, London, St Andrews, and Edinburgh), in the Netherlands (Nijmegen and Lochem), in Germany (Aachen and Bonn), in Sweden (B? astad and Sto- holm), and in Spain (Madrid). In 2005, the 17th International Workshop on - plementation and Application of Functional Languages will be held in Dublin, Ireland.

Your guide to the functional programming paradigm Functional programming mainly sees use in math computations, including those used in Artificial Intelligence and gaming. This programming paradigm makes algorithms used for math calculations easier to understand and provides a concise method of coding algorithms by people who aren't developers. Current books on the market have a significant learning curve because they're written for developers, by developers—until now. Functional Programming for Dummies explores the differences between the pure (as represented by the Haskell language) and impure (as represented by the Python language) approaches to functional programming for readers just like you. The pure approach is best suited to researchers who have no desire to create production code but do need to test algorithms fully and demonstrate their usefulness to peers. The impure approach is best suited to production environments because it's possible to mix coding paradigms in a single application to produce a result more quickly. Functional Programming For Dummies uses this two-pronged approach to give you an all-in-one approach to a coding methodology that can otherwise be hard to grasp. Learn pure and impure when it comes to coding Dive into the processes that most functional programmers use to derive, analyze and prove the worth of algorithms Benefit from examples that are provided in both Python and Haskell Glean the expertise of an expert author who has written some of the market-leading programming books to date If you’re ready to massage data to understand how things work in new ways, you’ve come to the right place!
