Parent State ID: 13
State Depth: 6
Action Taken: put-down(c)
Action Reasoning: To achieve the goal state, we need to place block c on the table first. Since the hand is currently holding block c, the best action is to put it down on the table.
State Description: The hand is empty. Block c is on the table and clear. Block a is on the table and clear. Block b is on the table with block d on top of it. Block d is on block b and is clear. The diagram now shows block c on the table, separate from the other blocks.
Action Path: ['unstack(c, d)', 'put-down(c)', 'unstack(d, a)', 'stack(d, b)', 'pick-up(c)', 'put-down(c)']
