Attempt Number: 2
Error Message: The action and resulting state have already been explored.

Action Reasoning:
The last action taken was a color change, and the robot is currently holding black paint. According to the logical conclusions, after a color change, the next step should be to paint the tile above the robot. The robot is currently on tile_1-3, and the tile directly above it, tile_0-3, is already painted white. Therefore, the robot should move to the right to tile_1-4, which is clear, to continue the painting sequence. This move will position the robot to paint the next tile in the sequence, tile_0-4, with black paint, which aligns with the goal state pattern.

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 holding black paint.

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