UGC NET CSE | December 2015 | Part 3 | Question: 45

Question

Reasoning strategies used in expert systems include

• A. Forward chaining, backward chaining and problem reduction
• B. Forward chaining, backward chaining and boundary mutation
• C. Forward chaining, backward chaining and back propagation
• D. Forward chaining, problem reduction and boundary mutation

Answer 1

Answer must be A

Forward chaining, backward chaining and problem reduction

forward chaining: Expert system is driven by the antecedent (left hand side)

backward chaining. : Expert system is driven by the consequent (right hand side)

Answer 2

The correct set of reasoning strategies used in expert systems includes:

• Forward chaining
• Backward chaining
• Problem reduction

So, the correct option is:

Forward chaining, backward chaining, and problem reduction
