Parent State ID: 7
State Depth: 4
Action Taken: put-down(a)
Action Reasoning: To achieve the goal state where block C is on block A, we should first put down block A on the table, freeing the hand to pick up block C next.
State Description: Block a is on the table and clear, block b is on the table and clear, block c is on the table and clear, block d is on the table and clear. The hand is empty. The diagram now shows all blocks on the table with no block being held.
Action Path: ['unstack(d, c)', 'put-down(d)', 'unstack(a, b)', 'put-down(a)']
