Parent State ID: 116
State Depth: 11
Action Taken: paint-down(robot1, tile_2-1, tile_1-1, white)
Action Reasoning: Since tile_2-2 is already painted and the robot is holding the white color, which matches the target color for tile_1-1, the next best action is to paint tile_1-1 white.
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)', 'left(robot1, tile_1-2, tile_1-1)', 'down(robot1, tile_1-1, tile_2-1)', 'up(robot1, tile_2-1, 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: Attempting to paint an already painted tile (tile_2-1) instead of the correct target tile (tile_1-1).
