Traditional constraint programming specifies an optimization problem by using a set of constraints and minimizing (or maximizing) objective functions. Unfortunately, general optimization problems may involve compound objectives whose optima are ...

Program analysis is essential for the optimized compilation of Constraint Handling Rules (CHRs) as well as the inference of behavioral properties such as confluence and termination. Up to now all program analyses for CHRs have been developed in an ad ...

Constraint Handling Rules (CHR) are a committed-choice declarative language which has been designed for writing constraint solvers. A CHR program consists of multi-headed guarded rules which allow one to rewrite constraints into simpler ones until a ...

This paper presents an inversion of the abstract unification operator for forward set-sharing analysis of logic programs. The inverted operator, called a backward abstract unification operator, computes all maximal pre-conditions for a given equation ...

Several program analysis problems can be cast elegantly as a logic program. In this paper we show how recently-developed techniques for incremental evaluation of logic programs can be refined and used for deriving practical implementations of ...

We present ReactiveML, a programming language dedicated to the implementation of complex reactive systems as found in graphical user interfaces, video games or simulation problems. The language is based on the reactive model introduced by Boussinot. ...

Proof-Carrying Code (PCC) is a general approach to mobile code safety in which the code supplier augments the program with a certificate (or proof). The intended benefit is that the program consumer can locally validate the certificate w.r.t. the "...
