Parent State ID: 113
State Depth: 11
Action Taken: paint-down(robot1, tile_2-1, tile_1-1, white)
Action Reasoning: The next best action is to "paint-down" on tile_2-1 with white, as the robot is on tile_1-1 and holding white, and this matches the goal state for tile_1-1.
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 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 that it must be clear.
