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

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

Reproduced from the original address: http://www.cnblogs.com/loveis715/p/5277051.htmlI recently used a graphical database to support a start-up project. In the process of using this kind of graphics database is actually very interesting. So here's a brief introduction to you.The NoSQL database is believed to have been heard. They can often be used to deal with a series of problems that traditional relational databases are difficult to solve. Typically

In the process of solving the actual problem, we often need to convert the directed graph into an undirected graph ), however, the independence between the directed graph with the same structure and the variables that the undirected graph can express is different. How to convert a directed

This article mainly introduces the JavaScript data structure and algorithm diagram and graph algorithm. This article describes the directed graph, unordered graph, simple graph, and graph traversal. For more information, see Graph

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. The input input contains multiple groups, each set in the following format. The first line contains two int
