SimpleAI 是 Python 实现的人工智能算法工具包,示例代码:

from simpleai.search import SearchProblem, astar    GOAL = 'HELLO WORLD'    class HelloProblem(SearchProblem):      def actions(self, state):          if len(state) < len(GOAL):              return list(' ABCDEFGHIJKLMNOPQRSTUVWXYZ')          else:              return []        def result(self, state, action):          return state + action        def is_goal(self, state):          return state == GOAL        def heuristic(self, state):          # how far are we from the goal?          wrong = sum([1 if state[i] != GOAL[i] else 0                      for i in range(len(state))])          missing = len(GOAL) - len(state)          return wrong + missing      problem = HelloProblem(initial_state='')  result = astar(problem)    print result.state  print result.path()
