The mean-end analysis process centers around the detection of differences between the current state and goal state. Once such a difference is isolated, an operator that can reduce the difference must be found. But perhaps that operator cannot be applied to the current state. So a sub-problem of getting to a state in which it can be applied is set up. The kind of backward chaining in which operators are selected and then sub goals are set up to establish the precondition of operators is called:
- A.
backward planning
- B.
goal stack planning
- C.
operator sub goaling
- D.
operator over loading
Attempted by 63 students.
Show answer & explanation
Correct answer: C
Mean-end analysis identifies differences between the current state and the goal state. When an operator cannot be applied directly to reduce a difference, a sub-goal is set up to satisfy its preconditions. This process of selecting operators and establishing necessary conditions via sub-problems is known as operator sub goaling.
