Parent State ID: 114
State Depth: 11
Action Taken: change-color(robot1, black, white)
Action Reasoning: The robot is on tile_1-2, holding black, and the next unpainted tile in row 1 is tile_1-3, which requires white paint. The best action is to change the robot's color to white to paint the next required tile.
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 occupied by robot1. 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)']

successfully verified the action of new state 135 with the path: The last action, `change-color(robot1, black, white)`, is valid because all preconditions are met: robot1 was holding black, and white is available. The current state accurately reflects the effects of this action, with robot1 now holding white. The visualization and natural language description of the current state are consistent with the actions taken and the initial state, making them valid.
