Graph depth-first traversal algorithm-Nirvana huofeng-blog Garden Depth-first Traversal Algorithm Correct the mistakes in the previous blog: the previous blog post has the suspicion of non-undirected graphs and not having to traverse the breadth first. In fact, the breadth-first search can also be used in Directed Graphs, because an undirected graph is a special directed

Zabbix the graphical advantages of monitoring more intuitive to show us which time period has an exception, usually graph display is often relatively single, so we need to monitor the resulting graphical integration together, so that we can view or compare anomalies at the same time, the following to see how to do?1, the first add graph, you can add in the host hosts, you can also add in templates template,

Introduction Partial reprint Wikimedia Encyclopedia:The Hungarian algorithm is one of the many algorithms used to solve the problem of linear task assignment, and it is a classical algorithm to solve the problem of the maximal matching of the binary graph, which can solve the problem in polynomial time, which was put forward by American mathematician Harold Kuhn in 1955. This algorithm is called the Hungarian algorithm because a large part of the algo

Given the current R Road, ask the farmer to build at least a few new roads to meet the requirements.Problem Solving Ideas:"There are at least 2 migration pathways for each migration of livestock, avoiding the repetitive path of migration. "That is, when the F farm is regarded as a point, the road as a side structure of a graph G, there is no bridge.Th

Please find out the number of connected features in the graph.Each node in the diagram contains 1 tags and a list of its neighbors. (a linked node (or node) of a non-graph is a sub-graph where any two vertices are connected by a path and are not connected to other vertices in the super graph.) ）Sample ExampleGiven diagram:A------B C \ | | \ | | \

Two-point graph matching summary binary graph matching1. The maximum matching of two graphs. In two sets, each element can be used only once. There are some matching relationships between the two sets, to find out the maximum number of matches, using the Hungarian algorithm, for each node constantly go to the augmented road to matchThere are several important properties:1, minimum point coverage = maximum m

This blog is reproduced from http://blog.csdn.net/lyy289065406/article/details/6762370First build the Model:Given a connected undirected graph G, it is necessary to add at least a few edges to make it a double-connected graph. The model is very simple, the road under construction we can think that side was deleted. Then a graph G is able to delete any edge, still

Yuta is worrying on this situation, so he gives Rikka some math tasks to practice. There is one of the them:Yuta have a non-direct graph with n vertices and n+1 edges. Rikka can choose some of the edges (at least one) and delete them from the graph.Yuta

Related concepts:Binary graphs: the set of points in Figure G can be divided into two disjoint subsets, and the two points of each edge in G belong to these two subsets respectively .Binary graph matching: The sub-figure m of the binary graph G has only one edge on each node, then M is a match .Great match: Cannot add edges to a binary graph and match matching
