Parent State ID: 135
State Depth: 12
Action Taken: paint-down(robot1, tile_2-2, tile_1-2, white)
Action Reasoning: The robot should paint down on tile_1-2 because it is one of the remaining tiles that needs to be painted white according to the goal. This ensures we are progressing systematically from row 2 to row 1.
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 painted white and the robot is standing on it. 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_1-2, 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)', 'change-color(robot1, black, white)', 'paint-down(robot1, tile_2-2, tile_1-2, white)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Attempting to paint an already painted tile violates constraints.
