Nettet2 T. Sato proved that the least solution of E˜ q(DB) in the sense of matrix ordering 1 can be con- verted to the least solution of E q(DB) and the latter gives the least Herbrand model M DB of DB as a set of adjacency matrices. We thus can compute M DB by way of solving E˜ q(DB) algebraically in the vector space RN.We emphasize that our approach … NettetWe now extend the PF(·), using the mechanism of the least Herbrand model construction, to a probability measure PDB(·) for the whole DB. Let ...
