Parent State ID: 0
State Depth: 1
Action Taken: unstack(b, c)
Action Reasoning: The goal is to have block 'c' on the table with blocks 'a' and 'd' stacked on top of it. To achieve this, we first need to clear block 'b' from the top of block 'c'. The immediate action is to unstack block 'b' from block 'c'.
State Description: The hand is holding block 'b'. Block 'a' is on the table. Block 'd' is on top of block 'a'. Block 'c' is on top of block 'd' and is now clear. Block 'b' is no longer on block 'c'. The hand is not empty, and block 'c' is clear.
Action Path: ['unstack(b, c)']

successfully verified the action of new state 1 with the path: The action `unstack(b, c)` is valid as all preconditions are met, and the effects match the current state. The current state's natural language description, diagram encoding, and visualization are accurate and consistent with the sequence of actions taken. The action logically progresses towards the goal state by freeing `block_c`.
