Uninformed search Python实现【译】 译自Uninformed search algorithms in Python版权所有,如需转载,请联系译者 图的搜索可以分为uninformed搜索和informed搜索,两者的区别是前者是的搜索是盲目的,它不知道目标节点在哪,而后者是启发式的搜索。 主要的uninformed 搜索分为以下三类: 深度优先搜索(DFS) 广度优先搜索(BF...
node = queue.pop() if node not in visited: visited.add(node) if node == goal: return for neighbor in graph[node]: if neighbor not in visited: queue.appendleft(neighbor) 一致代价搜索 该算法主要针对的是加权图,加权图每条边都有一个权值,权值低的边优先遍历,首先,我们创建一个加权图类: class...
(part 3)All these search algorithms are the same except for fringe strategiesConceptually, all fringes are priority queues (i.e. collections of nodes with attached priorities)Practically, for DFS and BFS, you can avoid the log(n) overhead from an actual priority queue, by using stacks and ...
