Constraints in Non-Boolean Contexts
In high-level constraint modelling languages, constraints can occur in non-Boolean contexts: implicitly, in the form of partial functions, or more explicitly, in the form of const...

Complexity of a CHR Solver for Existentially Quantified Conjunctions of Equations over Trees
Abstract. Constraint Handling Rules (CHR) is a concurrent, committed-choice, rule-based language. One of the first CHR programs is the classic constraint solver for syntactic equal...

Arc-Consistency for Non-Binary Dynamic CSPs
Constraint satisfaction problems (CSPs) provide a model often used in Artificial Intelligence. Since the problem of the existence of a solution in a CSP is an NP-complete task, man...

Strong Inverse Consistencies for Non-Binary CSPs
Domain filtering local consistencies, such as inverse consistencies, that only delete values and do not add new constraints are particularly useful in Constraint Programming. Alt...

An Algebraic Approach to the Complexity of Generalized Conjunctive Queries
Kolaitis and Vardi pointed out that constraint satisfaction and conjunctive query containment are essentially the same problem. We study the Boolean conjunctive queries under a mor...
