About the Book
ThisvolumecontainsthepapersfromLOPSTR2001,the11thInternational WorkshoponLogic-basedProgramSynthesisandTransformation. Topicsof- teresttoLOPSTRcoverallaspectsoflogic-basedprogramdevelopmentand,in particular, speci?cation, synthesis, veri?cation, transformation, specialization, analysis,optimization,composition,reuse,component-basedsoftwaredevel- ment,andsoftwarearchitectures. LOPSTR 2001 took place in the Coral Beach Hotel in Paphos (Cyprus) fromNovember28-30,2001. PastLOPSTRworkshopswereheldinManchester, UK(1991,1992,1998),Louvain-la-Neuve,Belgium(1993),Pisa,Italy(1994), Arnhem,TheNetherlands(1995),Stockholm,Sweden(1996),Leuven,Belgium (1997),Venice,Italy(1999),andLondon,UK(2000). LOPSTR2001wasco-locatedwiththe17thInternationalConferenceonLo- 1 gicProgramming(ICLP2001) andthe7thInternationalConferenceonPrinci- 2 plesandPracticeofConstraintProgramming(CP2001) . TheLOPSTRc- munitypro?tedalotfromthescienti?cdiscussions,thelecturesoftheinvited speakers,andthevarioussessionsofICLPandCP. I would like to express my gratitude to all the authors of the submitted papersandalltheattendeesfortheircommitmentandcooperation.
Amongthe submittedpapers,theProgramCommitteeselected13papersforpresentation. Aftertheworkshop,theauthorswereaskedtosubmitimprovedversionsoftheir paperswhichwerethenreviewedbytheProgramCommittee. The?nalversions havebeencollectedinthisvolume,whichalsoincludesthepaperbyourinvited speaker,NatarajanShankar(StanfordResearchInstitute,MenloPark,USA), onthegenerationofe?cientprogramsfromlogic. MywarmestthanksalsogotoallthemembersoftheProgramCommittee andtheadditionalreviewersfortheirdiligentworkandinvaluablehelp.
