Attempt Number: 4
Error Message: The action "left(robot1, tile_1-4, tile_1-3)" has already been explored.

Action Reasoning:
The last action taken was a "paint-up" action, where robot1 painted tile_0-4 black. According to the logical conclusions, after a "paint-up" action, the robot should move horizontally if there are unpainted tiles in the row above. Since all tiles in row 0 are painted, the robot should move down to the next row to continue painting. However, the previously suggested action "down(robot1, tile_1-4, tile_2-4)" was already explored and resulted in an error. Therefore, the robot should move left to tile_1-3 to prepare for further actions without repeating the previous error.

New State Description:
Robot1 moves from tile_1-4 to tile_1-3. Tile_1-4 becomes clear, and tile_1-3 is now occupied by robot1 holding a black paint gun.

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