Attempt Number: 3
Error Message: The action and resulting state have already been explored.

Action Reasoning:
The robot is currently at tile_1-2 holding a white paint gun. According to the goal state, the first tile to be painted is tile_0-0 with black paint. The robot should first move to tile_1-0. Since the robot is not at tile_1-0 yet, the best action is to move left to tile_1-1. This will help the robot get closer to tile_1-0, where it can then change the paint color to black and paint tile_0-0.

New State Description:
Robot1 has moved from tile_1-2 to tile_1-1. Tile_1-2 is now clear, and tile_1-1 is occupied by Robot1. Robot1 is still holding the white paint gun.

Action Chosen:
left(robot1, tile_1-2, tile_1-1)
