Parent State ID: 68
State Depth: 8
Action Taken: paint-down(robot1, tile_3-1, tile_2-1, black)
Action Reasoning: Since robot1 is on tile_2-1 and the target color for this tile is black, painting it will bring us one step closer to the goal state.
State Description: Tile tile_0-1: clear. Tile tile_0-2: clear. Tile tile_0-3: clear. Tile tile_1-1: clear. Tile tile_1-2: clear. Tile tile_1-3: clear. Tile tile_2-1: painted black. Tile tile_2-2: painted white. Tile tile_2-3: painted black. Robot1 is on tile_2-1, holding color black. 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)', 'paint-down(robot1, tile_3-1, tile_2-1, black)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Tile tile_3-1 does not exist, violating the precondition.
