Parent State ID: 89
State Depth: 13
Action Taken: paint-down(robot1, tile_2-1, tile_1-1, white)
Action Reasoning: The robot is on tile_1-1 and holding white, which matches the goal color for tile_2-1. The best action is to paint-down to achieve the goal state for this tile.
State Description: - Robot1 is on tile_1-1 and is holding the color white.- Tile_0-4 is clear.- Tile_1-1 is occupied by robot1.- Tile_1-2 is clear.- Tile_1-3 is clear.- Tile_1-4 is clear.- Tile_1-5 is clear.- Tile_2-1 is painted white and is no longer clear.- Tile_2-2 is painted white and is no longer clear.- Tile_2-3 is painted black and is no longer clear.- Tile_2-4 is painted white and is no longer clear.- Tile_2-5 is painted black and is no longer clear.- Both colors, white and black, are available for switching.
Action Path: ['down(robot1, tile_0-4, tile_1-4)', 'paint-down(robot1, tile_2-4, tile_1-4, white)', 'change-color(robot1, white, black)', 'right(robot1, tile_1-4, tile_1-5)', 'paint-down(robot1, tile_2-5, tile_1-5, black)', 'left(robot1, tile_1-5, tile_1-4)', 'left(robot1, tile_1-4, tile_1-3)', 'paint-down(robot1, tile_2-3, tile_1-3, black)', 'change-color(robot1, black, white)', 'paint-down(robot1, tile_2-2, tile_1-3, white)', '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, white)']

INACTIVE REASON: action path invalid: The last action `paint-down(robot1, tile_2-1, tile_1-1, white)` is invalid because the precondition that `tile_2-1` must be clear is not satisfied. The current state's natural language description and visualization are accurate, but the action does not bring us closer to the goal state.
