Parent State ID: 20
State Depth: 5
Action Taken: paint-down(robot1, tile_2-2, tile_1-2, black)
Action Reasoning: Since the robot is on tile_1-2 and holding black, it should paint tile_2-2, which aligns with the goal state requirement for that tile to be black. The next step is to paint-down the tile below.
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 clear. Tile tile_1-2 is occupied by robot1. Tile tile_1-3 is clear. Tile tile_2-1 is clear. Tile tile_2-2 is painted black. Tile tile_2-3 is clear. Robot1 is on tile_1-2, 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_2-2, tile_1-2, black)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Tile tile_2-2 is already painted white, and painting it black violates the goal state.
