Abstract
Cadmium is a rule based programming language for compiling solver independent constraint models to various solver dependent back-ends. Cadmium is based on a hybrid between Constraint Handling Rules (CHR) and term rewriting modulo Associativity, Commutativity and a restricted form of Distributivity (ACD) called Conjunctive Context (CC). Experience with using Cadmium in the G12 project shows that CC is a powerful language feature, as local model mapping can depend on some non-local context, such as variable declarations or other constraints. However, CC significantly complicates the Cadmium normalisation algorithm, since the normal form of a term may depend on what context it appears in. In th..
