The Rete Algorithm

The Rete algorithm is a pattern matching algorithm used for implementing rule-based systems. It was designed by Charles L. Forgy at Carnegie Mellon University and is particularly efficient at applying many rules or patterns to many objects, or facts, in a knowledge base. The algorithm is named after the Italian word for ‘network’, reflecting its network-like structure of nodes used for pattern matching.
