Parent State ID: 157
State Depth: 14
Action Taken: change-color(robot1, white, black)
Action Reasoning: Since tile_1-2 needs to be painted black and robot1 is currently holding white, we should change the color to black, which will also allow us to paint down on tile_1-2 in the subsequent move.
State Description: Tile tile_0-1 is clear. Tile tile_0-2 is occupied by robot1. 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_0-2, holding color black. Colors white and black are available for switching.
