Parent State ID: 3
State Depth: 4
Action Taken: put-down(d)
Action Reasoning: The goal is to have block d on block c. Since the hand is holding block d and block c is clear, the next best action is to put block d down on the table. This will free the hand and allow stacking d on c in the next step.
State Description: The hand is empty. Block a is on the table. Block b is on top of block a and is clear. Block c is on the table and clear. Block d is now on the table and clear. The diagram now shows d on the table, along with a and c.
Action Path: ['unstack(c, b)', 'put-down(c)', 'pick-up(d)', 'put-down(d)']
