The inference engine then passes along the conflict set to the second state, select rules.

In this state, the inference engine applies some selection strategy to determine which rules will actually be executed.

The inference engine then cycles back to the first state and is ready to start over again.

Each combination of the inference engine with a knowledge base becomes a unique expert system.

This, under the control of the inference engine, forms the system nucleus.

When asked whether trees die, the inference engine can draw the obvious conclusion and answer the question correctly.

An inference engine is a computer program that tries to derive answers from a knowledge base.

The inference engine combines the rules from the knowledge base with the patient's data.

The inference engine is a computer program designed to produce a reasoning on rules.

It is primarily used in educational institutions to demonstrate the principles of inference engines.
