ABSTRACT:
A mechanism for filtering production rules which express conditions to be satisfied, identifies during successive inference cycles rules whose conditions are satisfied for deduced facts. The mechanism includes a sorting system for ordering the conditions of the rules according to a sorting criterion in order to verify the conditions of the rules on the basis of an order in which the conditions are to be applied. The sorting mechanism activates the system for sorting the conditions of the rules only if the number of facts satisfying a rule condition is multiplied or divided by a variable factor between the current inference cycle and the last preceding inference cycle during which the sorting system was activated for that rule.
