Logic-Based Program Synthesis and Transformation

9th International Workshop, LOPSTR'99, Venice, Italy, September 22-24, 1999 Selected Papers

This volume contains the proceedings of the ninth international workshop on logic-based program synthesis and transformation (LOPSTR’99) which was held in Venice (Italy), September 22-24, 1999. LOPSTRistheannualworkshopandforumforresearchersinthelogic-based program development stream of computational logic. The main focus used to be on synthesis and transformation of logic programs, but the workshop is open to contributions on logic-based program development in any paradigm. Previous workshops were held in Manchester, UK (1991, 1992), Louvain-la-Neuve, B- gium (1993), Pisa, Italy (1994), Arnhem, The Netherlands (1995), Stockholm, Sweden (1996), Leuven, Belgium (1997), and Manchester, UK (1998). LOPSTR is a real workshop in the sense that it is a friendly and lively forum for presenting recent and current research as well as discussing future trends. Formal proceedings of the workshop are produced only after the workshop and contain only those papers selected by the program committee after a second refereeing process. The program committee of LOPSTR’99 accepted 20 extended abstracts for presentation at the workshop; then selected 14 papers for inclusion in the po- workshop proceedings. Selected papers cover all the main streams of LOPSTR’s topics: synthesis, specialization, transformation, analysis, and veri?cation. Ve- ?cation, transformation, and specialization methods are applied to functional, constraint, logic, and imperative programming.

There are several kinds of temporal logic, the most used in model-checking being
PLTL (Propositional Linear Temporal Logic) [37], CTL (Computation Tree Logic) [
8] and the mu-calculus [32]. Reachability analysis is a variant of ...

We propose a program specialization technique for locally stratified CLP(Z)
programs, that is, logic programs with linear constraints over the set Z of the
integer numbers. For reasons of efficiency our technique makes use of a
relaxation from ...

Logic Based Program Synthesis and Transformation

14th International Symposium, LOPSTR 2004, Verona, Italy, August 26-28, 2004, Revised Selected Papers

This book constitutes the thoroughly refereed postproceedings of the 14th International Symposium on Logic Based Program Synthesis and Transformation, LOPSTR 2004, held in Verona, Italy in August 2004. The 17 revised full papers presented were carefully selected and revised from 23 full paper and 11 extended abstract submissions. The papers are organized in topical sections on verification and analysis, theory and security, transformations, program development, termination, and program development and synthesis.

By bounding the degrees of these polynomials and their number, our method
reduces schema instantiation to non-linear constraint solving, based on the
theory of polynomial ideals. Although non-linear constraint solving is NP-hard, a

Logic-Based Program Synthesis and Transformation

18th International Symposium, LOPSTR 2008, Valencia, Spain, July 17-18, 2008, Revised Selected Papers

This book constitutes the thoroughly refereed post-conference proceedings of the 18th International Symposium on Logic-Based Program Synthesis and Transformation, LOPSTR 2008, held in Valencia, Spain, during July 17-18, 2008. The 11 revised full papers presented together with one invited talk were carefully reviewed and selected for inclusion in the book. LOPSTR traditionally solicits papers in the areas of specification, synthesis, verification, transformation, analysis, optimization, composition, security, reuse, applications and tools, component-based software development, software architectures, agent-based software development, and program refinement.

In this paper we present a procedure for representing the semantics of linear
hybrid automata (LHAs) as constraint logic programs (CLP); flexible and accurate
analysis and verification of LHAs can then be performed using generic CLP ...

13th International Symposium LOPSTR 2003, Uppsala, Sweden, August 25-27, 2003, Revised Selected Papers

This volume contains selected papers from LOPSTR 2003, the 13th Inter- tional Symposium on Logic-Based Program Synthesis and Transformation. The LOPSTR series is devoted to research in logic-based program development. P- ticular topics of interest are speci?cation, synthesis, veri?cation, transformation, specialization, analysis, optimization, composition, reuse, component-based so- ware development, agent-based software development, software architectures, design patterns and frameworks, program re?nement and logics for re?nement, proofs as programs, and applications and tools. LOPSTR 2003 took place at the University of Uppsala from August 25 to August 27 as part of PLI 2003 (Principles, Logics, and Implementations of High- Level Programming Languages). PLI was an ACM-organized confederation of conferences and workshops with ICFP 2003 (ACM-SIGPLAN International C- ference on Functional Programming) and PPDP 2003 (ACM-SIGPLAN Inter- tional Conference on Principles and Practice of Declarative Programming) as the main events. The LOPSTR community pro?ted from the shared lectures of the invited speakers, and the active scienti?c discussions enabled by the co-location. LOPSTR 2003 was the thirteenth in a series of events. Past events were held in Manchester, UK (1991, 1992, 1998), Louvain-la-Neuve, Belgium (1993), Pisa, Italy (1994), Arnhem, The Netherlands (1995), Stockholm, Sweden (1996), L- ven, Belgium (1997), Venice, Italy (1999), London, UK (2000), Paphos, Cyprus (2001), and Madrid, Spain (2002).

We identify a restricted class of terms of the lambda calculus, here called weak
linear, that includes the linear lambda-terms keeping their good properties of
strong normalization, non-duplicating reductions and typability in polynomial time

Operations Research Proceedings 2007

Selected Papers of the Annual International Conference of the German Operations Research Society (GOR)

The symposium Operations Research 2007 was held from September 5-7, 2007 at the Saarland University in Saarbru ̈cken. This international conference is at the same time the annual meeting of the German - erations Research Society (GOR). The transition in Germany (and many other countries in Europe) from a production orientation to a service society combined with a continuous demographic change generated a need for intensi?ed Op- ations Research activities in this area. On that account this conference has been devoted to the role of Operations Research in the service industry. The links to Operations Research are manifold and include many di?erent topics which are particularly emphasized in scienti?c sections of OR 2007. More than 420 participants from 30 countries made this event very international and successful. The program consisted of three p- nary,elevensemi-plenaryandmorethan300contributedpresentations, which had been organized in 18 sections. During the conference, the GOR Dissertation and Diploma Prizes were awarded. We congratulate all winners, especially Professor Wolfgang Domschke from the Da- stadt University of Technology, on receiving the GOR Scienti?c Prize Award.
