A fundamental question in programming language semantics is when two programs should be considered equivalent. In this paper we introduce a notion of operational equivalence for CHR programs and user-defined constraints. Constraint Handling Rules (CHR) is a high-level language for writing constraint solvers either from scratch or by modifying existing solvers.
