Parent State ID: 39
Action Taken: left(robot1, tile_1-3, tile_1-2)
Action Reasoning: The last action was "paint-up," so the next step is to move the robot horizontally to continue painting the row above. Since the robot is currently at tile_1-3 and the goal is to alternate colors, the next logical step is to move the robot to tile_1-2 to prepare for painting the next tile above it. This avoids repeating the previous move to tile_1-4, which resulted in an error.
State Description: Robot1 moves from tile_1-3 to tile_1-2. Tile_1-3 becomes clear, and tile_1-2 is now occupied by Robot1, which is holding black paint.
