用Python代码画出在迷宫中15个位置放置宝藏,玩家需从入口进入,集齐15个宝藏后到达出口,请问如何行走距离最短?

好的,针对你的问题,我可以提供一份Python代码,实现在迷宫中放置宝藏、玩家行走、寻找宝藏并求解最短路径的功能。代码如下:
```python
import random
import numpy as np
import queue
# 迷宫大小
N = 10
# 迷宫地图
maze = np.zeros((N, N))
# 宝藏数量
treasure_count = 15
# 随机放置宝藏
for i in range(treasure_count):
while True:
x, y = random.randint(0, N-1), random.randint(0, N-1)
if maze[x, y] == 0:
maze[x, y] = 2
break
# 入口和出口位置
start_pos = (0, 0)
end_pos = (N-1, N-1)
# 宝藏数量和玩家当前寻找到的宝藏数量
total_treasure_count = np.sum(maze == 2)
found_treasure_count = 0
# BFS算法求解最短路径
q = queue.Queue()
q.put(start_pos)
visited = set()
visited.add(start_pos)
path = {start_pos: None}
while not q.empty():
curr_pos = q.get()
if curr_pos == end_pos:
break
for next_pos in [(curr_pos[0]+1, curr_pos[1]), (curr_pos[0]-1, curr_pos[1]),
(curr_pos[0], curr_pos[1]+1), (curr_pos[0], curr_pos[1]-1)]:
if next_pos[0] < 0 or next_pos[0] >= N or next_pos[1] < 0 or next_pos[1] >= N:
continue
if maze[next_pos] == 1 or next_pos in visited:
continue
visited.add(next_pos)
path[next_pos] = curr_pos
q.put(next_pos)
# 回溯路径
curr_pos = end_pos
shortest_path = []
while curr_pos != start_pos:
shortest_path.append(curr_pos)
curr_pos = path[curr_pos]
shortest_path.append(start_pos)
shortest_path.reverse()
# 计算最短路径上的宝藏数量
for pos in shortest_path:
if maze[pos] == 2:
found_treasure_count += 1
# 输出结果
print('迷宫地图:')
print(maze)
print('入口位置:', start_pos)
print('出口位置:', end_pos)
print('宝藏数量:', total_treasure_count)
print('最短路径:', shortest_path)
print('行走距离:', len(shortest_path)-1)
print('寻找到的宝藏数量:', found_treasure_count)
```
代码中,使用随机数生成器放置15个宝藏,然后使用BFS算法求解最短路径。在回溯最短路径时,顺便计算路径上的宝藏数量,以便输出寻找到的宝藏数量。最后输出最短路径、行走距离和寻找到的宝藏数量等结果。
