Parent State ID: 79
Action Taken: paint-up(robot1, tile_0-4, tile_1-3, white)
Action Reasoning: The last action was a color change, specifically changing the color to white. According to the rules, after changing the color, the next best action is to paint the tile directly above the robot's current position. Robot1 is currently on tile_1-3 and holding white paint. The tile directly above, tile_0-4, is not painted yet. Therefore, the best action is for Robot1 to paint tile_0-4 white.
State Description: Tile_0-4 is now painted white. Robot1 remains on tile_1-3, holding white paint.
