这是一个使用 A* 算法解决 8 拼图问题的 Python 实现。
- 使用 A 搜索算法* 寻找最优解。
- 启发函数采用 曼哈顿距离。
- 支持输出每一步的操作及状态变化。
- 安装依赖:无额外依赖,确保已安装 Python(3.x)。
- 执行脚本:
python solvepuzzle.py
修改 start_state 变量以设置不同的初始拼图状态。例如:
start_state = "87153642_" # 初始状态程序会输出从初始状态到目标状态的移动步骤,并展示每次操作后的拼图状态。
默认目标状态为:
123
456
78_
This is a Python implementation of solving the 8-puzzle problem using the A* algorithm.
- Uses the A* search algorithm to find the optimal solution.
- The heuristic function uses Manhattan distance.
- Supports outputting each move and puzzle state change.
- Install dependencies: No additional dependencies are needed, ensure you have Python (3.x) installed.
- Run the script:
python solvepuzzle.py
Modify the start_state variable to set a different initial puzzle configuration. For example:
start_state = "87153642_" # Initial stateThe program will output the steps from the initial state to the goal state, along with the puzzle state after each move.
The default goal state is:
123
456
78_
