State ID: 54
Action Path: ['unstack(c, d)', 'put-down(c)', 'unstack(d, a)', 'put-down(d)', 'pick-up(a)', 'stack(a, c)', 'pick-up(b)', 'stack(b, a)', 'pick-up(d)', 'stack(d, b)']
Action Taken: stack(d, b)
State Description: The hand is now empty. Block 'd' is on block 'b' and is clear. Block 'b' is not clear and is on block 'a'. Block 'a' is not clear and is on block 'c'. Block 'c' is on the table and not clear.
Action Reasoning: To achieve the goal state, we need to place block 'd' on block 'b'. Since the hand is currently holding block 'd' and block 'b' is clear, the best action is to stack 'd' on 'b'.
