Parent State ID: 146
State Depth: 13
Action Taken: paint-down(robot1, tile_2-3, tile_1-3, white)
Action Reasoning: Since robot1 is on tile_1-3 and holding color white, the next step is to paint tile_2-3 white as it is directly below and clear, successfully progressing towards the goal state.
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 clear. Tile tile_1-3 is occupied by robot1. Tile tile_2-1 is painted black. Tile tile_2-2 is painted white. Tile tile_2-3 is painted white. Robot1 is on tile_1-3, 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)', 'right(robot1, tile_1-1, tile_1-2)', 'right(robot1, tile_1-2, tile_1-3)', 'change-color(robot1, black, white)', 'paint-down(robot1, tile_2-3, tile_1-3, white)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Tile tile_2-3 is painted white instead of black, violating the goal state's constraints.
