ABSTRACT:
A pattern match method is the primary component of any rule-based inference engine or database search method. Equivalence class projection is used in a discrimination match network, such that only equivalence class tokens (and not working memory objects) are propagated down the network, then only the first object which is a member of any specific equivalence class will cause an actual propagation down through the net. Subsequent changes which are either the creation of new objects which are members of a known equivalence class or the removal of any object but the last member of that equivalence class can totally avoid propagation downward in that section of the discrimination network.
