Abstract |
The non-Horn magic sets (NHM) have been presented in order to enhance forward reasoning provers by combining top-down and bottom-up provings. The NHM method is a natural extension of Horn magic sets a...nd is applicable to non-Horn clauses. There are two types of transformations to get non-Horn magic sets from the given clause sets: depth-first NHM and breadth-first NHM. We present a proof of completeness for depth-first NHM by giving a proof-tree transformation procedure.show more
