Title: System for processing non-deciding state
Inventor: SATO TAKESHI
IPC: G06N5/04
Filed: 1987-02-20
Abstract: PURPOSE:To quickly process a non-deciding state by performing automatically the back-track processing to secure the application of a substitute rule even though a rule inapplicable state is produced. CONSTITUTION:A pattern match processing part 2-1 applies the rules read successively out of a rule base 3 while they are stored in a work memory 1 and also carried out successively such processes as deletion, addition, etc. The processes end when a desired state set previously is obtained or all rules are applied.
