Attempt Number: 4
Error Message: The action and resulting state have already been explored.

Action Reasoning:
The last action taken was "paint-up," where the robot painted the tile above it. According to the logical conclusions, after a "paint-up" action, the robot should move horizontally if there are any unpainted tiles in the row above. In this case, the robot should move right to tile_1-4, as tile_0-4 is not painted yet. This action moves the robot closer to the next unpainted tile in the row above, allowing it to continue the painting sequence.

New State Description:
Robot1 moves from tile_1-3 to tile_1-4. Tile_1-3 becomes clear, and tile_1-4 is now occupied by Robot1, which is still holding black paint.

Action Chosen:
right(robot1, tile_1-3, tile_1-4)
