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()
