Parent State ID: 113
State Depth: 11
Action Taken: paint-down(robot1, tile_2-1, tile_1-1, white)
Action Reasoning: The robot is holding color white and is on tile_1-1. The correct action is to paint the tile directly below, tile_2-1, with white. This aligns with the goal state requirement for tile_1-1 to be painted white, bringing us closer to the goal without violating constraints.
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 painted white. Tile tile_1-2 is clear. Tile tile_1-3 is clear. Tile tile_2-1 is painted black. Tile tile_2-2 is painted white. Tile tile_2-3 is painted black. Robot1 is on tile_1-1, holding color white. 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)', 'right(robot1, tile_1-2, tile_1-3)', 'left(robot1, tile_1-3, tile_1-2)', 'left(robot1, tile_1-2, tile_1-1)', 'paint-down(robot1, tile_2-1, tile_1-1, black)', 'change-color(robot1, black, white)', 'paint-down(robot1, tile_2-1, tile_1-1, white)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Tile_2-1 is already painted black, violating the precondition and goal state.
