Logic-Based Program Synthesis and Transformation

21st International Symposium, LOPSTR 2011, Odense, Denmark, July 18-20, 2011. Revised Selected Papers

This book constitutes the thoroughly refereed proceedings of the 21st International Symposium on Logic-Based Program Synthesis and Transformation, LOPSTR 2011, held in Odense, Denmark in July 2011. The 6 revised full papers presented together with 8 additional papers were carefully reviewed and selected from 28 submissions. Among the topics covered are specification, synthesis, verification, analysis, optimization, specialization, security, certification, applications and tools, program/model manipulation, and transformation techniques for any programming language paradigm.

We propose a program specialization technique for locally stratified CLP(Z)
programs, that is, logic programs with linear constraints over the set Z of the
integer numbers. For reasons of efficiency our technique makes use of a
relaxation from ...
