This postproceedings volume of the 17th International Symposium on Logic-Based Program Synthesis and Transformation, LOPSTR 2007, examines program termination, program transformation, constraint solving and analysis as well as software engineering.

Program Termination.- Proving Termination with (Boolean) Satisfaction.- Termination Analysis of Logic Programs Based on Dependency Graphs.- Type-Based Homeomorphic Embedding and Its Applications to Online Partial Evaluation.- Program Transformation.- Towards a Normal Form for Mercury Programs.- Aggregates for CHR through Program Transformation.- Preserving Sharing in the Partial Evaluation of Lazy Functional Programs.- Denotation by Transformation.- Constraint Solving and Analysis.- Generation of Rule-Based Constraint Solvers: Combined Approach.- A Scalable Inclusion Constraint Solver Using Unification.- Annotation Algorithms for Unrestricted Independent And-Parallelism in Logic Programs.- A Flexible, (C)LP-Based Approach to the Analysis of Object-Oriented Programs.- Software Engineering.- Snapshot Generation in a Constructive Object-Oriented Modeling Language.- Synthesis of Data Views for Communicating Processes.- Action Refinement in Process Algebra and Security Issues.
