"Observe carefully the small facts upon which the largest inferences depend. Abstract A variety of techniques within logic programming have developed for treating negated formulae. These essentially involve constructibility restrictions which are imposed upon complexity classes of quantifieational formulae, and which thereby determine models and model(More)
