Which term describes reasoning about the system's own strategies?

  • A.Object-level reasoning, which draws conclusions about the domain the system is working in
  • B.Deep reasoning
  • C.Hypothetical reasoning, which explores the consequences of assumptions not yet established
  • D.Meta-level reasoning

Answer: D

Meta-level knowledge says which rules to prefer, when to give up on a line of enquiry and how to organise the search, as distinct from knowledge about the domain itself. TEIRESIAS and NEOMYCIN both made strategy explicit in this way, which improved both explanation and tutoring. Object-level, deep and hypothetical reasoning name different things. Making control knowledge declarative is the general move. Framing the question as which quantity the change acts upon makes the answer follow without calculation.
