This book constitutes the refereed proceedings of the 8th International Symposium on Functional and Logic Programming, FLOPS 2006, held in Fuji-Susono, Japan, in April 2006. The 17 revised full papers presented together with 2 invited contributions were carefully reviewed and selected from 51 submissions. The papers are organized in topical sections on data types, FP extensions, type theory, LP extensions, analysis, contracts, as well as Web and GUI.

The Fifth International Symposium on Practical Aspects of Declarative L- guages (PADL 2003) was held in New Orleans on 13-14 January 2003. It was colocatedwiththe30thAnnualACMSymposiumonPrinciplesofProgramming Languages(POPL2003). We received 57 submissions, a record for PADL. One of the strengths of PADL is that it draws papers from both sides of the declarative divide, from boththefunctionalandlogicprogrammingcommunities.Ofthe57submissions, 25werefunctionaland32werelogical, withsomenotableoverlaps.

This year PADL instituted a "Most Practical" paper award, for the paper that best exempli?ed the goals of PADL. The award went to "Data mining the yeast genome in a lazy functional language," Amanda Clare and Ross D.

This comprehensive guide shows you how to master the most important changes to Java since it was first released. Generics and the greatly expanded collection libraries have tremendously increased the power of Java 5 and Java 6. But they have also confused many developers who haven't known how to take advantage of these new features. "Java Generics and Collections" covers everything from the most basic uses of generics to the strangest corner cases. It teaches you everything you need to know about the collections libraries, so you'll always know which collection is appropriate for any given task, and how to use it. Topics covered include: Fundamentals of generics: type parameters and generic methods; Other new features: boxing and unboxing, foreach loops, varargs; Subtyping and wildcards; Evolution not revolution: generic libraries with legacy clients and generic clients with legacy libraries; Generics and reflection; Design patterns for generics; Sets, Queues, Lists, Maps, and their implementations; Concurrent programming and thread safety with collections; ane Performance implications of different collections. Generics and the new collection libraries they inspired take Java to a new level. If you want to take your software development practice to a new level, this book is essential reading.

Computation, itself a form of calculation, incorporates steps that include arithmetical and non-arithmetical (logical) steps following a specific set of rules (an algorithm). This uniquely accessible textbook introduces students using a very distinctive approach, quite rapidly leading them into essential topics with sufficient depth, yet in a highly intuitive manner. From core elements like sets, types, Venn diagrams and logic, to patterns of reasoning, calculus, recursion and expression trees, the book spans the breadth of key concepts and methods that will enable students to readily progress with their studies in Computer Science.

The Glasgow functional programming group has held a workshop each summer since 1988. The entire group, accompanied by a selection of colleagues from other institutions, retreats to a pleasant Scottish location for a few days. Everyone speaks briefly, enhancing coherence, cross fertilisation, and camaraderie in our work. The proceedings of the first workshop were published as a technical report. Demand for this was large enough to encourage wider publication, and subsequent proceedings have been published in the Springer-Verlag Workshops in Computing series. These are the proceedings of the-meeting held 12-14 August 1991, in Portree on the Isle of Skye. A preliminary proceedings was prepared in advance of the meeting. Most presentations were limited to a brief fifteen minutes, outlining the essentials of their subject, and referring the audience to the pre-print proceedings for details. Papers were then refereed and rewritten, and you hold the final results in your hands. A number of themes emerged at this year's workshop, including relational algebra and its application to hardware design, partial evaluation and program transformation, implementation techniques, and strictness analysis. We were especially pleased to see applications of functional programming emerge as a theme. One of the sessions was devoted to a lively discussion of applications, and was greatly enhanced by our industrial participants. The workshop was organised by Kei Davis, Cordelia Hall, Rogardt Heldal, Carsten Kehler Holst, John Hughes, John O'Donnell, and Satnam Singh all from the University of Glasgow."
