因此,整体时间复杂度为O(V + E)。 Python字典实现案例 在Python中,可以使用collections.deque来实现队列,利用字典构建图结构,并使用哈希表(集合set)记录已访问节点,这是一种优化方案。 以下是代码示例: from collections import deque def bfs(graph, start): visited = set() # 初始化访问标记集合 queue = de...
To bake muffins in her bak...最短路径分词 最短路径分词 中文分词有很多方法,比如N-最短路径法,N元语言模型,CRF模型等等。大致可以分为两类:一是机械化的分词,二是用机器学习方法分词。最短路径算法可以划分到第一种。这个算法效果并不是最好的,大体和IK分词打成平手。今天用最简洁语言描述一下:这个算法...
