Contents

The formally well-founded presentation introduces the common classes of constraint programming languages and constraint systems in a uniform way. It also includes application examples from real life. We first introduce the basic ideas behind the family of (concurrent) constraint logic programming languages in a calculus-based framework. Constraint solving algorithms are specified and implemented in the constraint handling rules language (CHR) in a uniform high-level executable notation. The most common constraint domains, their solvers and applications such as Boolean constraints for circuit design, terms and trees for unification, linear polynomial equations for financial and engineering applications and finite domains for scheduling, are presented.
