Multiprocessor Execution of Logic Programs addresses the problem of efficient implementation of logic programming languages, specifically Prolog, on multiprocessor architectures. The approaches and implementations developed attempt to take full advantage of sequential implementation technology developed for Prolog (such as the WAM) while exploiting all forms of control parallelism present in logic programs, namely, or-parallelism, independent and-parallelism and dependent and-parallelism. Coverage includes a thorough survey of parallel implementation techniques and parallel systems developed for Prolog. Multiprocessor Execution of Logic Programs is recommended for people implementing parallel logic programming systems, parallel symbolic systems, parallel AI systems, and parallel theorem proving systems. It will also be useful to people who wish to learn about the implementation of parallel logic programming systems.

This book presents an integrated approach to sustainably fulfilling energy requirements, considering various energy-usage sectors and applicable technologies in those sectors. It discusses smart cities, focusing on the design of urban transport systems and sources of energy for mobility. It also shares thoughts on individual consumption for ensuring the sustainability of energy resources and technologies for emission reductions for both mobility and stationary applications. For the latter, it examines case studies related to energy consumption in the manufacturing sector as well as domestic energy requirements. In addition it explores various distribution and policy aspects related to the power sector and sources of energy such as coal and biomass. This book will serve as a valuable resource for researchers, practitioners, and policymakers alike.

This volume contains the proceedings of the 21st International Conference on Logic Programming which was held in Sitges (Barcelona), Spain, from October 2nd to 5th, 2005. The conference was colocated with the International Conf- ence on ConstraintProgramming(CP 2005)and the following 6 post-conference workshops: - CICLOPS 2005: Colloquium on Implementation of Constraint and Logic Programming Systems - CSLP 2005: Constraint Solving and Language Processing - WCB 2005: Constraint Based Methods for Bioinformatics - WLPE 2005: Logic-Based Methods in Programming Environments - MoVeLog 2005: Mobile Code Safety and Program Veri?cation Using C- putational Logic Tools - CHR 2005: Constraint Handling Rules The conferencecoincided with a solareclipse, whichoccurredon October 3rd and was visible in Sitges. No conference activities were scheduled at the time of the eclipse to allow delegates to view this extraordinary astronomical event. Since the ?rst conference that was held in Marseilles in 1982, ICLP has been the premier international conference for presenting research in logic progr- ming. In this edition of the conference, extra attention was given to novel - plications of logic programming and to work providing novel integrations of di?erent areas. Colocation with CP 2005 further reinforced these themes, as it provided an opportunity for the exchange of ideas and cross-fertilization among two areaswhich havecommon roots. ICLP 2005and CP 2005sharedthe invited speakers to underscore this e?ort. ICLP 2005 broke new ground by holding a doctoral consortium for the ?rst time in the ICLP series of conference.

Declarative languages have traditionally been regarded by the mainstream c- puting community as too impractical to be put to practical use. At the same time, traditionalconferencesdevotedto declarativelanguagesdo not haveissues related to practice as their central focus. Thus, there are few forums devoted to discussion of practical aspects and implications of newly discovered results and techniques related to declarative languages. The goal of the First International Workshop on Practical Aspects of Declarative Languages (PADL) is to bring together researchers, practitioners and implementors of declarative languages to discuss practical issues and practical implications of their research results. The workshop was held in San Antonio, Texas, during January 18-19, 1999. This volume contains its proceedings. Fifty three papers were submitted in response to the call for papers. These papers were written by authors belonging to twenty one countries from six c- tinents. Each paper was assigned to at least two referees for reviewing. Twenty four papers were nally selected for presentation at the workshop. Many good papers could not be included due to the limited duration of the workshop. The workshop included invited talks by Mark Hayden of DEC/Compaq Systems - search Center, speaking on \Experiences Building Distributed Systems in ML," and Mark Wallace of Imperial College Center for Planning And Resource C- trol (IC-PARC), speaking on \ECLiPSe: Declarative Specic ation and Scalable Implementation.

Logic programming refers to execution of programs written in Horn logic. Among the advantages of this style of programming are its simple declarativeand procedural semantics, high expressive power and inherent nondeterminism. The papers included in this volume were presented at the Workshop on Parallel Logic Programming held in Paris on June 24, 1991, as part of the 8th International Conference on Logic Programming. The papers represent the state of the art in parallel logic programming, and report the current research in this area, including many new results. The three essential issues in parallel execution of logic programs which the papers address are: - Which form(s) of parallelism (or-parallelism, and-parallelism, stream parallelism, data-parallelism, etc.) will be exploited? - Will parallelism be explicitly programmed by programmers, or will it be exploited implicitly without their help? - Which target parallel architecture will the logic program(s) run on?

This book constitutes the thoroughly refereed post-conference proceedings of the 23rd International Symposium on Logic-Based Program Synthesis and Transformation, LOPSTR 2013, held in Madrid, Spain, in September 2013. The 13 revised full papers presented together with 2 invited talks were carefully reviewed and selected from 21 submissions during two rounds of reviewing and improvement. 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.
