拓扑排序邻接矩阵集合算法框架In order to decrease the complexity of the topological sort algorithms which are based on adjacency matrix, the single-vertex algorithm framework was expanded to the set algorithm framework, and
一、什么是拓扑排序 在图论中,拓扑排序(Topological Sorting)是一个有向无环图(DAG, Directed Acyclic Graph)的所有顶点的线性序列。且该序列必须满足下面两个条件: 每个顶点出现且只出现一次。 若存在一条从顶点 A 到顶点 B 的路径,那么在序列中顶点 A 出现在顶点 B 的前面。 有向无环图(DAG)才有拓扑排序...

1. sort all the edges in the order of weight. 2. pick the smallest of all the edges, create a set that contains two ends, if the set not in the result, merge it into the result set. else skip. 3. repeat 2 until all the vertices are in the result. The running time is ElogE....
tsort_each_child is used to iterate for child nodes of a given node. The equality of nodes are defined by eql? and hash since TSort uses Hash internally. Installation Add this line to your application's Gemfile: gem 'tsort' And then execute: $ bundle install Or install it yourself ...

2.1Insertion Sort - To be honest you should probably know all major sorting algorithms, not just insertion sort. It's just basic knowledge and you never know when it can help. 2.2Analysis of Algorithms - you can skip the small intro, but know the rest. ...
do, but certain tasks have to be performed before other tasks. These precedence constraints form a directed acyclic graph, and any topological sort (also known as alinear extension) defines an order to do these tasks such that each is performed only after all of its constraints are satisfied....
4.3.4 Topological sort A topological sort is a linear ordering of vertices in a directed acyclic graph (DAG). Given a DAG G = (V, E), a topological sort algorithm returns a sequence of vertices in which the vertices never come before their predecessors on any paths. In other words, if...
