Question:

In a forward planner, a state can be represented in terms of the sequence of actions that lead to that state.

(a) Explain how to check whether the precondition of an action is satisfied, given such a representation.

(b) Explain how to do cycle pruning (page 109) in such a representation. You can assume that all of the states are legal. (Some other program has ensured that the preconditions hold.)

[Hint: Consider the composite action (Exercise 6.6) consisting of the first k or the last k actions at any stage.]
