How Computers Think Using Rete

The Rete algorithm allows machines to process thousands of complex rules instantly. Instead of checking every rule from scratch, it remembers past results to handle new data changes with incredible speed.

Invented in the late 1970s, this clever technique is the secret engine behind many expert systems. By storing a history of what it has already checked, the system only processes what has actually changed rather than re-evaluating the entire knowledge base. This efficiency mimics a sort of intelligent memory, allowing software to draw conclusions as data flows in. It remains a foundational concept for building smart, rule-heavy applications today.
