Connectivity Problem of a graph: delete some elements (points or edges) in the graph so that the two specified points s and t are not connected (there is no path from s to t ), you must delete at least a few elements.Graph connectivity is divided into point connectivity and Edge Connectivity:(1) Point Connectivity: Only Delete points. delete at least a few points. (Of course, s and t cannot be deleted. Here

1 Overview Dynamic topology coloring is a kind of power system advanced Application System, topology analysis is an important part of electric power speciality, it is the basis of power automation analysis, it directly reflects the power equipment modeling of automation system, provides the system's real-time running network structure, and can be dynamic coloring, Provide users with an intuitive way to understand the operating mode of the system. 2 D

POJ 1144 Network (undirected graph component cut point), poj1144 Address: POJ 1144 Cut Point. There are two conditions for determining whether a point is a cut point: If u is a cut point, and only if the following one is satisfied 1. If u is the root of a tree, u must have more than one subtree. 2. if u is not the root of a tree, (u, v) is the edge of a tree branch. When Low [v]> = DFN [u. Then we can find

[24 questions about network stream] minimum path coverage (Bipartite Graph Matching) programming questions, 24 bipartiteQuestion Principle: Minimum path overwrite = point-matching number;It is easy to understand: the two points can be matched, which is equivalent to putting them in and querying the set, and querying the number of sets is the number of paths;However, my understanding of

This blog post for the migration, written on May 16, 2015, does not represent my current views and views. Original address: http://blog.sina.com.cn/s/blog_6022c4720102w0d8.html1. Prefacefirst, a concept-the minimum cut. What is the minimum cut? On the network stream, the smallest stream is truncated so that no traffic can flow from the source point to the sink point. Think about it, in fact, the biggest traffic flow. So we can get a theorem- minimum c
