拓扑排序
拓扑排序拓扑排序的定义 对一个有向无环图(Directed Acyclic Graph简称DAG)G进行拓扑排序,是将G中所有顶点排成一个线性序列,使得图中任意一对顶点u和v,若边(u,v)∈E(G),则u在线性序列中出现在v之前。通常,这样的线性序列称为满足拓扑次序(Topological Order)的序列,简称拓扑序列—— [ 百度百科 ] 拓扑排序表示了顶点按照边的方向出现的先后顺序。...

贝叶斯网络
贝叶斯网络、马尔科夫随机场(MRF, Markov RandomField)和因子图都属于概念图,因此它们都归属于机器学习中的概念图模型(PGM,Probability Graphical Model). 一:定义 贝叶斯网络,又称信念网络(Belief Network, BN), 或有向无环图模型,是由一个有向无环图(DAG,Directed acyclic graphical model...

普林斯顿大学《算法II》第二周学习笔记 Directed Graph
有向图的遍历和无向图的遍历类似,主要是DFS和BFS。对于DAG(Directed Acyclic Graph),还有一个很重要的拓扑的概念,拓扑排序的倒序可以用Depth-first search来生成,类似二叉树的后序遍历。见Depthfirst Order in Algs4private vo...
