Attempt Number: 2
Error Message: The action paint-up(robot1, tile_0-4, tile_1-4, white) has already been explored.

Action Reasoning:
The last action taken was a color change, where Robot1 changed its paint gun color from black to white. According to the logical conclusions, after a color change, the next best action is to paint the tile directly above the robot. Robot1 is currently on tile_1-4, holding white paint. The tile directly above, tile_0-4, is not painted. Therefore, the best action is to paint tile_0-4 with the white color Robot1 is holding. This action will bring us closer to the goal state by painting the next required tile in the alternating color pattern.

New State Description:
Tile_0-4 is now painted white. Robot1 remains on tile_1-4, holding white paint. The row above Robot1 is now fully painted in the required alternating color pattern.

Action Chosen:
paint-up(robot1, tile_0-4, tile_1-4, white)
