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

Action Reasoning:
The last action taken was moving the robot left from tile_1-4 to tile_1-3. According to the logical conclusions, after a move action, the next step should be to change the color of the paint gun. The robot is currently holding white, but the goal state requires tile_0-3 to be painted black. Therefore, the best action is to change the color from white to black to prepare for painting the next tile correctly.

New State Description:
Robot1, located on tile_1-3, changes its paint gun color from white to black. The robot is now ready to paint the next tile above it with the correct color.

Action Chosen:
change-color(robot1, white, black)
