This library provides CLP(B), Constraint Logic Programming over Boolean variables. It can be used to model and solve combinatorial problems such as verification, allocation and covering tasks.
CLP(B) is an instance of the general CLP(X) scheme (section 8), extending logic programming with reasoning over specialised domains.
The implementation is based on reduced and ordered Binary Decision Diagrams (BDDs).
