An Arc-Consistency Algorithm for Dynamic and Distributed Constraint Satisfaction Problems
Abstract. This paper presents the new DDAC4 algorithm for dynamic arc consistency enforcement in distributed Constraint Satisfaction Problems. The algorithm is an adaptation of the...

The Complexity of Homomorphism and Constraint Satisfaction Problems Seen from the Other Side
We give a complexity theoretic classification of homomorphism problems for graphs and, more generally, relational structures obtained by restricting the left hand side structure ...

A SAT-Based Version Space Algorithm for Acquiring Constraint Satisfaction Problems
Constraint programming is rapidly becoming the technology of choice for modelling and solving complex combinatorial problems. However, users of this technology need significant ex...

Unbiased Statistics of a Constraint Satisfaction Problem - a Controlled-Bias Generator
: We show that estimating the complexity (mean and distribution) of the instances of a fixed size Constraint Satisfaction Problem (CSP) can be very hard. We deal with the main two ...

Combinatorial Proof that Subprojective Constraint Satisfaction Problems are NP-Complete
Abstract. We introduce a new general polynomial-time constructionthe fibre construction- which reduces any constraint satisfaction problem CSP(H) to the constraint satisfaction pr...
