Many approaches to multi-relational learning require the computation of database frequencies in the presence of nonexistent links. The corresponding ILP problem is to compute the number of groundings that satisfy a given conjunction of literals in a relational database, where one or more of the literals is negated. We present a fast new dynamic programming algorithm for this problem. The databa...
