Parent State ID: 4
State Depth: 4
Action Taken: stack(c, b)
Action Reasoning: To achieve the goal state where Block C is on Block B, we should stack Block C onto Block B since Block B is clear and the hand is holding Block C.
State Description: Block C is on top of Block B and is clear. Block B is no longer clear. Block A is on the table and is clear. Block D is on the table and is clear. The hand is empty.
Action Path: ['unstack(b, c)', 'put-down(b)', 'pick-up(c)', 'stack(c, b)']
