In artificial intelligence, an expert system is a computer system that emulates the decision-making ability of a human expert. Expert systems are designed to solve complex problems by reasoning about knowledge, like an expert, and not by following the procedure of a developer as is the case in conventional programming. The first expert systems were created in the 1970s and then proliferated in the 1980s. Expert systems were among the first truly successful forms of AI software.

Expert/Rule Engine that updates facts atomically?

Atomically might not be the right word. When modelling cellular automata or neural networks, usually you have two copies of the system state. One is the current state, and one is the state of the next step that you are updating. This ensures…
