Parent State ID: 72
Action Taken: left(robot1, tile_1-4, tile_1-3)
Action Reasoning: The last action taken was a color change, which means the next logical step is to paint the tile above the robot. Robot1 is currently holding white paint and is on tile_1-4. The tile directly above, tile_0-4, needs to be painted black according to the goal state. However, since Robot1 is holding white paint, the next step should be to move the robot to the left, to tile_1-3, where it can change the paint color to black, which matches the goal requirement for tile_0-4.
State Description: Robot1 has moved from tile_1-4 to tile_1-3. The robot is still holding white paint. Tile_1-4 is now clear, and tile_1-3 is occupied by Robot1.
