Abstract: Constraint programming is a paradigm for computing with mathematical relations named constraints. It is a declarative approach to describe many real-world problems including scheduling, vehicles routing, biology and musical composition. Constraint programming must be contrasted with procedural approaches that describe how a problem is solved, whereas constraint models describe what the problem is. The part of how a constraint problem is solved is left to a general constraint solver. Unfortunately, there is no solving algorithm efficient enough to every problem, because the search strategy must often be customized per problem to attain reasonable efficiency. This is a daunting task that requires expertise and good understanding on the solver’s intrinsics. Moreover, higher-level constraint-based languages provide limited support to specify search strategies. In this dissertation, we tackle this challenge by designing a programming language for specifying search strategies. The dissertation is constructed around two axes:
