conjunctive queries prolonged by union and negation, which by Codd's theorem correspond to relational algebra and first-buy logic
The fixpoint semantics suggest an algorithm for computing the small design: Start with the set of floor facts in the program, then consistently incorporate penalties of The principles until a fixpoint is achieved. This algorithm is called naïve evaluation.
