Parent State ID: 16
Action Taken: change-color(robot1, black, white)
Action Reasoning: The last action taken was a move to the right. According to the logical conclusions, after a move, the next step should be to change the color of the paint gun. Since Robot1 is currently holding black paint and the next tile to be painted (tile_0-2) should be black, we should change the color to white in preparation for the subsequent tile (tile_0-3), which needs to be painted white. This aligns with the alternating color pattern required in the goal state.
State Description: Robot1, located on tile_1-2, changes its paint gun color from black to white. Tile_1-2 remains occupied by Robot1, and tile_1-1 is clear. The tiles above (tile_0-0 to tile_0-4) remain unchanged in terms of paint.
Action Path: ['left(robot1, tile_1-4, tile_1-3)', 'left(robot1, tile_1-3, tile_1-2)', 'left(robot1, tile_1-2, tile_1-1)', 'change-color(robot1, white, black)', 'paint-up(robot1, tile_0-1, tile_1-1, black)', 'right(robot1, tile_1-1, tile_1-2)', 'change-color(robot1, black, white)']
