| Abstract: | An efficient method the Rete for implementing a forward reasoning system is proposed. It is an extension of and improvement on the famous multi-pattern multi-objective match algorithm, the Rete. In the Rete, a database tost network is built by means of the upward match relation bstwosn the predicate sample parameters to save the match state information and to reduce match time; the rules have been compiled into Pascal target cods and guards are added in front of each rule to speed up the selection and execution of rules. The design idea and implementation of the Rete are also discussed. It is shown that the match time of the Rete is the same as that of the Rete when the objective contains only constant parameters. |
