Dataflow analyses can have mutually beneficial interactions. Previous efforts to exploit these interactions have either (1) iteratively performed each individual analysis until no...
We present a declarative debugger for lazy functional logic programs with polymorphic type discipline. Whenever a computed answer is considered wrong by the user (error symptom), ...
We present fault localization techniques suitable for diagnosing end-to-end service problems in communication systems with complex topologies. We refine a layered system model th...
We present a Language Prototyping System that facilitates the modular development of interpreters from independent semantic buildks. The abstract syntax is modelled as the fixpoint...
This paper extends the well-known technique of slicing to synchronous reactive programs. Synchronous languages exemplified by Esterel, Lustre, Signal and Argos, novel model of exe...
