Logic-Based Program Synthesis and Transformation 24th International Symposium, LOPSTR 2014, Canterbury, UK, September 9-11, 2014. Revised Selected Papers

This book constitutes the thoroughly refereed post-conference proceedings of the 24th International Symposium on Logic-Based Program Synthesis and Transformation, LOPSTR 2014, held in Canterbury, UK, in September 2014. The 18 revised full papers presented together with 2 invited talks were carefully reviewed and selected from 34 submissions. The aim of the LOPSTR series is to stimulate and promote international research and collaboration on logic-based program development. The papers are organized along a set of thematic tracks: program analysis and transformation, constraint handling rules, termination analysis, security, program testing and verification, program synthesis, program derivation, semantic issues in logic programming and program transformation and optimization.
