Functional and Logic Programming: 9th International Symposium, FLOPS 2008, Ise, Japan, April 14-16, 2008, Proceedings

This volume contains the proceedings of the 9th International Symposium on Functional and Logic Programming (FLOPS 2008), held in Ise, Japan, April 14-16, 2008 at the Ise City Plaza. FLOPS is a forum for research on all issues concerning functional progr- ming and logic programming. In particular it aims to stimulate the cro- fertilization as well as integration of the two paradigms. The previous FLOPS meetings took place in Fuji-Susono (1995), Shonan (1996), Kyoto (1998), Tsukuba(1999),Tokyo(2001),Aizu (2002),Nara(2004),and againFuji-Susono (2006). Since its 1999 edition, FLOPS proceedings have been published by Springer in itsLecture Notes in Computer Science series,as volumes 1722,2024, 2441, 2998 and 3945, respectively. In response to the call for papers, 59 papers were submitted. Each paper was reviewedbyatleastthreeProgramCommittee members,withthe helpofexpert external reviewers.

After careful and thorough discussion,the ProgramCommittee selected20 papers(33%)for presentationat theconference.Inadditiontothe20contributedpapers,thesymposiumincluded talks by three invited speakers: Peter Dybjer (Chalmers University of Techn- ogy), Naoki Kobayashi (Tohoku University) and Torsten Schaub (University of Potsdam).
