SimpleAI 是 Python 实现的人工智能算法工具包，示例代码：

01	from simpleai.search import SearchProblem, astar

02

03	GOAL = 'HELLO WORLD'

04

05	class HelloProblem(SearchProblem):

06	def actions(self, state):

07	if len(state) < len(GOAL):

08	return list(' ABCDEFGHIJKLMNOPQRSTUVWXYZ')

09

else:

10

return []

11

12	def result(self, state, action):

13	return state + action

14

15	def is_goal(self, state):

16	return state == GOAL

17

18	def heuristic(self, state):

19	# how far are we from the goal?

20	wrong = sum([1 if state[i] != GOAL[i] else 0

21	for i in range(len(state))])

22	missing = len(GOAL) - len(state)

23	return wrong + missing

24

25

26	problem = HelloProblem(initial_state='')

27	result = astar(problem)

28

29	print result.state

30	print result.path()
