Inference strategy in which the conclusion is already known. The system works backwards to determine which known premises entail that conclusion. This is the opposite of the way reasoning ordinarily proceeds, with each premise evaluated to see what follows from it. It is also a computerized search technique used in production systems that begins with the action clause of a rule and works backward through a chain of rules in an attempt to find a veritable set of condition clauses, also termed as goal oriented, or top-down search.
