Parent State ID: 47
State Depth: 6
Action Taken: left(robot1, tile_1-2, tile_1-1)
Action Reasoning: Since tile_2-2 and tile_2-3 are already painted, the next step is to move robot1 to a position where it can paint tile_2-1. First, move robot1 left to tile_1-1, then paint tile_2-1 black.
State Description: Tile tile_0-1 is clear. Tile tile_0-2 is clear. Tile tile_0-3 is clear. Tile tile_1-1 is occupied by robot1 holding color black. Tile tile_1-2 is clear. Tile tile_1-3 is clear. Tile tile_2-1 is clear. Tile tile_2-2 is painted white. Tile tile_2-3 is painted black. Robot1 is on tile_1-1, holding color black. Colors white and black are available for switching.
Action Path: ['right(robot1, tile_0-1, tile_0-2)', 'down(robot1, tile_0-2, tile_1-2)', 'paint-down(robot1, tile_2-2, tile_1-2, white)', 'change-color(robot1, white, black)', 'paint-down(robot1, tile_2-3, tile_1-2, black)', 'left(robot1, tile_1-2, tile_1-1)']

successfully verified the action of new state 53 with the path: The last action `left(robot1, tile_1-2, tile_1-1)` is valid as all preconditions are met, and the effects are correctly updated in the current state. The action logically positions the robot to continue painting tiles according to the goal state. The natural language and diagram encoding descriptions are accurate, and the visualization correctly reflects the current state.
