Constraint based draw programs require users to understand and manage relationships between drawing elements. By establishing constraint relationships among elements the user effe...
Many program analyses can be reduced to graph reachability problems involving a limited form of context-free language reachability called Dyck-CFL reachability. We show a new redu...
Formal specifications are more useful and easier to develop if they are executable. In this work, we describe a system for executing specifications written in the Java Modeling Lan...
An important challenge in constraint programming is to rewrite constraint models into executable programs calculating the solutions. This phase of constraint processing may requir...
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...
