Implementing Propagators for Tabular Constraintssing a table of compatible tuples rather than using a formula. In the paper we study the implementation of filtering algorithms (propagators) for such constraints that we call tabular constraints. In particular, we propose compact representations of extensionally defined binary constraints and we de

Learning Approximate ConsistenciesThe behavior of the consistency to be learned is taken as the set of examples on which the learning process is applied. The best possible expression of this operator in a given language is then searched. We present sufficient conditions for the learned solver to be correct and complete with respect

Abstracting Soft Constraints: Some Experimental Results on Fuzzy CSPscases to pass to an abstract version of a given soft problem, and then bring some useful information from the abstract problem to the concrete one. This will hopefully make the search for a solution, or for an optimal solution, of the concrete problem, faster..In this paper we review the main concep

Tradeoff Generation Using Soft Constraints configurators. It has been reported how tradeoffs can be modeled as additional constraints. This paper presents a formal framework for tradeoff generation based on the semiring approach to soft constraints. In particular, user preferences and tradeoffs are, respectively, represented as soft constra

A Rule Language for Interactions manage interactions of call-back functions that apply on a store of data. This store can freely be structured as an array, a list, a set of communication channels, etc. Our rule language can be seen as an abstract machine to specify and implement interactive component languages. We also propose su

A Generic Trace Schema for the Portability of CP(FD) Debugging Toolsre specific and have to be redesigned and re-implemented for each constraint solver whereas much could be factorized. This article sets the foundations to enable debugging tools to be defined almost independently from finite domain solvers, and conversely, tracers to be built independently from thes
