Abstract

The operation of a deletion-directed search strategy for resolution-based proof procedures is discussed. The strategy attempts to determine the satisfiability of a set of input clauses while at the same time minimizing the cardinality of the set of retained clauses. Distribution, a new clause deletion rule which is fundamental to the operation of the search strategy, is also described.
