Beta node indexing in a rule engine

An apparatus comprising:

• a rule repository to store a set of one or more rules;
• and
• a rule engine core coupled to the rule repository to create a network based on the set of one or more rules, the network comprising at least one multiple-input node, the at least one multiple-input node comprising a plurality of memories, each of the plurality of memories associated with a distinct input of the at least one multiple-input node, and to generate a single index for at least one of the plurality of memories of the at least one multiple-input node based on a plurality of attributes of elements within the at least one of the plurality of memories, the single index comprising a plurality of composite keys, each of the plurality of composite keys comprising a value of each of the plurality of attributes.

A computer-readable medium that provides instructions that, when executed by a processor, will cause the processor to perform operations comprising:

• creating a network based on a set of one or more rules, the network comprising at least one multiple-input node, the at least one multiple-input node comprising a plurality of memories, each of the plurality of memories associated with a distinct input of the at least one multiple-input node;
• and
• generating a single index for at least one of the plurality of memories of the at least one multiple-input node of the network based on a plurality of attributes of elements within the at least one memory, the single index comprising a plurality of composite keys, each of the plurality of composite keys comprising a value of each of the plurality of attributes.
