Analysis of Heuristic Synergiescombinations based on products and quotients, and a less familiar form of combination based on weighted sums of ratings from a set of base heuristics, some of which result in definite improvements in performance. Then, using recent results from a factor analytic study of heuristic performance, which

Complexity Analysis of Heuristic CSP Search Algorithms. are the number of variables and the maximal domain size of the underlying CSP, respectively..In this paper we show that a combination of heuristic methods of constraint solving can reduce the time complexity. In particular, we prove that the FC-CBJ algorithm combined with the fail-first variable o

A Type System for CHR host language, such as Prolog or Java, this type system is parameterized by the type system of the host language. We show the consistency of the type system for CHR w.r.t. its operational semantics. We also study the case when the host language is a constraint logic programming language, typed with

Views and Iterators for Generic Constraint Implementations scale, translate, and negate variables. The paper shows how to make constraint implementations generic and how to reuse a single generic implementation with different views for different constraints. A wide range of applications of views exemplifies their usefulness and their potential for simplify

The proposed results are interesting because they establish connection between theoretical and practical approaches to CSP research.

A Type System for CHRxecution model CLP+CHR. This system is implemented through an extension of our type checker TCLP for constraint logic languages. We report on experimental results about the type-checking of twelve CHR solvers and programs, including TCLP itself.
