Convert undirected graphs to point-to-double-connected graphsDefinition: Point-double connect refers to a path with at least two points that are not duplicated between any twoThere are two kinds of cases, one is connected graph, the other is non-connected graph① Connectivity DiagramFirst, find all the points in the graph-the two connected components, and then ind
. Kruskal algorithm-merging forests into trees Third, topological sortingTopological order : if there is a forward path from V to W in the diagram, V must precede w. The sequence of vertices that satisfy this condition is called a topological order.The process of obtaining a topological order is topological ordering .AOV (Activity on Vertex) If there is a reasonable topological order, it must be a directed acyclic graph (Directed acyclic
There are n schools under the OA for school enrollment, and each school needs to have relatively independent data management and statistics, When we use a line chart, we will show all the lines in its series.

In the future, you can drag the irregular image directly regardless of the selected two layers (select the layer and click the link icon below, you can connect the layers), for example: PS tips: Before clicking the picture to select a layer, remember to do the fo
Recently began to seriously learn the algorithm, with the Sedgewick of the "algorithms". Much of the content is the same as the data structure, the difference is the content of the algorithm more explanation. I often keep track of the difficulties I encounter in learning algorithms and how to solve them.The problem of judging the existence loop is encountered when learning the topological sort. The problem of judging the ring is divided into the direction gr
The "Best match, Perfect match, and Hungarian algorithm" of the "binary graph" is a special image that is particularly easy to understand for several concepts related to the dichotomy. This article is part of a major excerpt from this blog post.There are other posts to consider:A series of interesting writing algorithms--Hungarian algorithmHungarian algorithm for binary graph matching1.

From: http://www.cppblog.com/RyanWang/archive/2009/05/01/81617.html Standalone set: A set of independent sets is a subset of the vertex set of a graph, the exported child graph of the subset does not contain edges. If a set of independent sets is not a subset of any set of independent sets, then the independent set is called a maximal independent set. The independent set with the highest number of vertice

The Dijkstra algorithm, which is used to search the right graph, finds the shortest distance of two points in the graph, neither DFS search nor BFS search.The Dijkstra algorithm is applied to the graph with no power graph, or all sides have equal weights, and the Dijkstra algorithm is equivalent to BFS search.Http://ww
Graph structure Exercise--judging whether a given graph has a valid topological sequence Time limit:1000ms Memory limit:65536k The topic describes whether there is a valid topological sequence for a given graph to determine if there is one.

Graph Theory conclusion, Graph Theory AlgorithmThe connectivity of a graph has a point with a unique degree of 0 in a non-ring graph, which can be reached by any point (because of the absence of a ring, we can start from any point and go forward, must end at a point with an outbound degree of 0.) any point with a non-I
Dependency graph (Dependency graph)At any time, a file depends on another file, and Webpack this as a dependency between the files.This allows Webpack to receive non-code resources (Non-code Asset) (example or Web fonts), and can use them as dependencies to provide to your application.Webpack start with a list of modules defined in the command line or configuration file to process your application.Starting
