Refining the Basic Constraint Propagation Algorithm
Constraint propagation is the main feature of any constraint solver. This is thus of prime importance to manage constraint propagation as efficiently as possible, justifying the us...

Full Restart Speeds Learning
Because many real-world problems can be represented and solved as constraint satisfaction problems, the development of effective, efficient constraint solvers is important. A solv...

Solution Strategies for Multi-domain Constraint Logic Programs
We integrate a logic programming language into Meta-S, a flexible and extendable constraint solver cooperation system, by treating resolution as constraint solver. This new approac...

Minion: A Fast Scalable Constraint Solver
Abstract. We present Minion, a new constraint solver. Empirical results on standard benchmarks show orders of magnitude performance gains over state-of-the-art constraint toolkits....

Watched Literals for Constraint Propagation in Minion
Efficient constraint propagation is crucial to any constraint solver. We show that watched literals, already a great success in the satisfiability community, can be used to provide...

Combining Lazy Narrowing with Disequality Constraints
Abstract. We investigate an extension of a lazy functional logic language, which uses term disequations both in programs and in computed answers. The semantic properties of the lan...

A Minimal Extension of the WAM for clp(FD)
nt an abstract instruction set for a constraint solver over finite domains, which can be smoothly integrated in the WAM architecture. It is based on the use of a single primitive...

Resolution of Constraints in Algebras of Rational Trees
Abstract. This work presents a constraint solver for the domain of rational trees. Since the problem is NP-hard the strategy used by the solver is to reduce as much as possible, in...

Narrowing the Gap between Set-Constraints and CLP(SET)-Constraints
We compare two (apparently) rather different set-based constraint languages, and we show that, in spite of their different origins and aims, there are large classes of constraint ...
