Using Constraint Programming and Local Search Methods to Solve Vehicle Routing Problems
We use a local search method we term Large Neighbourhood Search (LNS) for solving vehicle routing problems. LNS meshes well with constraint programming technology and is analogous...

A Framework for Assertion-Based Debugging in Constraint Logic Programming
Abstract. We propose a general framework for assertion-based debugging of constraint logic programs. Assertions are linguistic constructions which allow expressing properties of pr...

Modelling CSP Solution Algorithms with Petri Decision Nets
The constraint paradigm provides powerful concepts to represent and solve different kinds of planning problems, e. g. factory scheduling. Factory scheduling is a demanding optimiz...

Random Constraint Satisfaction: Theory Meets Practice
Abstract. We study the experimental consequences of a recent theoretical result by Achlioptas et al. that shows that conventional models of random problems are trivially insoluble ...

Constraints for Object Recognition in Aerial Images - Handling of Unobserved Features
In this paper we will show how constraint solving methods can be applied for the recognition of buildings in aerial images. Object models are transformed to constraint representati...

Optimizing with Constraints: A Case Study in Scheduling Maintenance of Electric Power Units
A well-studied problem in the electric power industry is that of optimally scheduling preventative maintenance of power generating units within a power plant. We show how these pr...

Suggestion Strategies for Constraint-Based Matchmaker Agents
In this paper we describe a paradigm for contentfocused matchmaking, based on a recently proposed model for constraint acquisition-and-satisfaction. Matchmaking agents are conceiv...

Generation of Test Patterns for Differential Diagnosis of Digital Circuits
In a faulty digital circuit, many (single) faulty gates may explain the observed findings. In this paper we are mostly concerned, not in obtaining alternative diagnoses, but rathe...
