Parent State ID: 67
Action Taken: left(robot1, tile_1-4, tile_1-3)
Action Reasoning: The last action taken was "paint-up," which means the next step should be to move the robot horizontally if there are unpainted tiles in the row above. Since the robot is currently on tile_1-4 and the row above (row 0) has unpainted tiles, the robot should move left to tile_1-3. This action will position the robot to paint the next unpainted tile in the sequence, which is tile_0-2.
State Description: Robot1 moves from tile_1-4 to tile_1-3, holding the black paint gun. Tile_1-4 is now clear, and tile_1-3 is occupied by Robot1.
