机器人以1-9之间的特定数字向上、向下、向左、向右移动任意4个方向,这通常涉及到路径规划、状态转移和决策制定。这种问题在人工智能、机器人学和自动化控制中非常常见。

示例代码:
import heapq
def heuristic(a, b):
return abs(a[0] - b[0]) + abs(a[1] - b[1])
def astar(grid, start, goal):
neighbors = [(0,1),(0,-1),(1,0),(-1,0)]
close_set = set()
came_from = {}
gscore = {start:0}
fscore = {start:heuristic(start, goal)}
oheap = []
heapq.heappush(oheap, (fscore[start], start))
while oheap:
current = heapq.heappop(oheap)[1]
if current == goal:
data = []
while current in came_from:
data.append(current)
current = came_from[current]
return data
close_set.add(current)
for i, j in neighbors:
neighbor = current[0] + i, current[1] + j
tentative_g_score = gscore[current] + heuristic(current, neighbor)
if 0 <= neighbor[0] < len(grid) and 0 <= neighbor[1] < len(grid[0]):
if grid[neighbor[0]][neighbor[1]] == 1:
continue
else:
continue
if neighbor in close_set and tentative_g_score >= gscore.get(neighbor, 0):
continue
if tentative_g_score < gscore.get(neighbor, 0) or neighbor not in [i[1] for i in oheap]:
came_from[neighbor] = current
gscore[neighbor] = tentative_g_score
fscore[neighbor] = tentative_g_score + heuristic(neighbor, goal)
heapq.heappush(oheap, (fscore[neighbor], neighbor))
return False
grid = [
[0, 0, 0, 0, 0],
[1, 1, 0, 1, 0],
[0, 0, 0, 0, 0],
[0, 1, 1, 1, 0],
[0, 0, 0, 0, 0]
]
start = (0, 0)
goal = (4, 4)
path = astar(grid, start, goal)
print(path)
