Parent State ID: 26
State Depth: 10
Action Taken: stack(a, d)
Action Reasoning: To achieve the goal state, the hand is currently holding block 'a'. We should place it on block 'c' since 'c' needs to support 'a' in the goal state.
State Description: The hand is empty. Block 'a' is stacked on block 'd'. Block 'b' is clear and on the table. Block 'c' is clear and on the table. Block 'd' is not clear, as it is supporting block 'a'. The table supports blocks 'b', 'c', and 'd'.
Action Path: ['unstack(b, c)', 'put-down(b)', 'unstack(c, d)', 'put-down(c)', 'unstack(d, a)', 'put-down(d)', 'pick-up(a)', 'put-down(a)', 'pick-up(a)', 'stack(a, d)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: The action places block 'a' on block 'd' instead of block 'c', not aligning with the goal state.
