This volume contains the proceedings of the 7th International Symposium on Functional and Logic Programming (FLOPS 2004), held in Nara, Japan, April 7-9, 2004 at the New Public Hall, Nara. FLOPS is a forum for research on all issues concerning functional progr- mingandlogicprogramming. Inparticularitaimstostimulatethecross-fertili- tion as well as the integration of the two paradigms. The previous FLOPS me- ings took place in Fuji-Susono (1995), Shonan (1996), Kyoto (1998), Tsukuba (1999), Tokyo(2001)and Aizu (2002). The proceedingsofFLOPS 1999, FLOPS 2001 and FLOPS 2002 were published by Springer-Verlag in the Lecture Notes in Computer Science series, as volumes 1722, 2024 and 2441, respectively. In response to the call for papers, 55 papers were submitted by authors from 1 Australia (1), Austria (1), Canada (1), China (4), Denmark (2), Estonia ( ), 2 1 1 France (3 ), Germany (4 ), Italy (1), Japan (15), the Netherlands (1), Oman 2 4 1 1 (1), Portugal ( ), Singapore (2), Spain (8), UK (3), and USA (6 ). Each paper 2 4 was reviewed by at least three program committee members with the help of expert external reviewers. The program committee meeting was conducted el- tronically for a period of 2 weeks in December 2003. After careful and thorough discussion, the program committee selected 18 papers (33%) for presentation at theconference. Inadditiontothe18contributedpapers, thesymposiumincluded talks by three invited speakers: Masami Hagiya (University of Tokyo), Carsten Schur ] mann (Yale University), and Peter Selinger (University of Ottawa)

This book constitutes the refereed proceedings of the 18th International Conference on Logic Programming, ICLP 2002, held in Copenhagen, Denmark, in July/August 2002.The 29 revised full papers presented together with two invited contributions and 13 posters were carefully reviewed and selected from 82 submissions. All current aspects of logic programming and computational logic are addressed.

This volume LNCS 12735 constitutes the papers of the 18th International Conference on the Integration of Constraint Programming, Artificial Intelligence, and Operations Research, CPAIOR 2021, which was held in Vienna, Austria, in 2021. Due to the COVID-19 pandemic the conference was held online. The 30 regular papers presented were carefully reviewed and selected from a total of 75 submissions. The conference program included a Master Class on the topic "Explanation and Verification of Machine Learning Models".

This book constitutes the thoroughly refereed post-conference proceedings of the 28th International Symposium on Logic-Based Program Synthesis and Transformation, LOPSTR 2018, held in Frankfurt/Main, Germany, in September 2018.The 11 revised full papers were carefully reviewed and selected from 29 submissions. In addition to the 11 papers, this volume includes 3 abstracts of invited talks and 2 abstracts of invited tutorials. The papers are grouped into the following topics: analysis of term rewriting; logic-based distributed/concurrent programming; analysis of logic programming; and program analysis.
