Show answerHide answer

Correct answer: (A) Sequence of levels

Explanation

A planning graph consists of a sequence of levels that correspond to time steps in the plan; level 0 is the initial state. Each level contains a set of literals (all that could be true at that time step) and a set of actions (all whose preconditions could be satisfied at that step). It is used to obtain heuristic estimates, and a solution can be extracted using GRAPHPLAN.
