Abstract: . 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 highlevel
language for writing constraint solvers either from scratch or by
modifying existing solvers.
We give a decidable, sufficient and necessary syntactic condition for operational
equivalence of terminating and confluent CHR... (Update)
