  • Reticular discrimination network for specifying real-time conditions
    Patent number: 5390286
    Abstract: A reticular discrimination net utilized in expert systems is adapted to accommodate responses only to critical changes in data by utilizing @T and @F clauses which describe changing conditions. By placing these mechanisms into a traditional reticular discrimination net as test nodes and configuring the mechanisms to function as traditional test nodes, the computation and interaction among data elements is minimized. This also enables the network to keep track of the state of the match process, thus allowing the network to respond only to critical changes in data.

  • RETE network with provisional satisfaction of node conditions
    Patent number: 5072405
    Abstract: An expression comprising conditions is evaluated based on values of data elements presented to a network of a kind in which the conditions are represented by nodes and the relationships among conditions in the expression are represented by links among the nodes, by storing information that identifies which conditions represented by at least some of the nodes have been satisfied by the values of the data elements, and testing the stored information in accordance with the expression as a basis for evaluating said expression.
