edge, then the side () and the side) the path P appears alternately, so P is an augmented orbit relative to M, in this way, we can replace edge 1 and 4 with edge 2 and 3. Then we can add 1 to the number of matched edge sets. The Hungarian algorithm is the same as the constant pursuit of augmented rail implementation. Obviously, if the two vertices in the bipartite graph are N and m, the maximum number of matching values should be less than or equal to min (n, m ); therefore, we can enumerate ev

Data structure (implemented in C) ------- depth-first traversal of graphs, data structure ------- [This article is my own learning notes. You are welcome to repost it, but please note the Source: http://blog.csdn.net/jesson20121020] Algorithm Description: Assume that the initial State of a given graph G is that all vertices have never been accessed. If you select a vertex vi in G as the initial starting point, the depth-first traversal can be defin

// ********************************* The following is a reprinted *** **************************************** Bipartite Graph Matching Algorithm Summary Hungarian algorithm for maximum matching of bipartite graphs A bipartite graph is such a graph. Its vertices can be classified into two sets X and Y. All edges are associated with two vertices. Exactly one belongs to set X, and the other belongs to set Y. Maximum matching: the matching with the large

The following program can be used to create a forward graph, a forward mesh, an no-direction graph, and a non-net. The graph says that if there is an edge between vertices, it is represented in the matrix with 1, and infinity is represented by 0. In the network, the Edge is the corresponding weight value.The traversal of graphs can be divided into depth-first traversal and breadth-first traversal.The idea of a depth-first traversal is to select an unr

Adjacency tables are another efficient means of storing representations of graphs. Each vertex u establishes a single linked list, and each node in the list represents an edge The row of the adjacency matrix.The Adjvex field indicates a adjacency point V of U, and Nxtarc points to the next edge node of U. If it is a net, increase the weight on the edge of a W-domain storage.The constructor completes the dynamic space storage allocation for one-dimensi

Asking how to take can make the most children happy. The problem of solving ideas: the maximum independent set of two graphs, for two children can not be happy at the same time, the final maximum

variable diagram is described here, do not make the chart too complicated, otherwise you will lose the chart "intuitive" advantages.To show the correlation of 3 variables, it is best to use three-dimensional coordinates of the three-dimensional statistical chart, but because in fact still on the plane to the three-dimensional diagram, the three-dimensional map is not convenient to use.(1) When a variable is a categorical variable, the two-dimensional graph can be expanded, so that the two-dimen

The adjacency multiple table of graphs is another representation of the graph without direction. It differs from the adjacency table only in that the adjacency table represents an edge with two vertices, whereas the adjacency multiple table uses a vertex to represent an edge. This makes adjacency multiple tables convenient for certain operations. For example, to mark a searched edge or delete an edge.Here is the structure of the adjacency multiple tab

Graph adjacency table before implementation, always a little bit of a problemIt is now clear that the original head node is content and has been used as a marker positionIn the final analysis, this is a combination of cis-and chain-like storage structureBut still do not know why, this structure compared to the adjacency matrix in addition to the space storage above has a great advantage, and access to adjacent nodes convenientI don't know what else he has to be.(In fact, it is because of the cha

You can use APIs for generating dynamic graphs, such as jfreechart in Java. However, you need to deploy the class library.CodeComplex. Google chart provides an API for generating dynamic graphs through URL calls. For more information about the website, see: Http://code.google.com/intl/zh-CN/apis/chart/ This is a pie chart generated by calling this API Based on the market share in the report about th

This paper summarizes the realization of several shortest path algorithms of graphs: depth or Breadth First search algorithm, Freud algorithm, Dijkstra algorithm, Bellman-ford algorithm1), depth or breadth First search algorithm (solve single source shortest path)To access all depth traversal paths or breadth-first paths from the starting node, the path to the endpoint node is multiple, and the shortest path is the shortest one.Here's the core code:vo

Algorithm generation notes 8 (algorithm 2 for graphs-Shortest Path Problems) The shortest path in the figure is divided into two types: single-source shortest path problem and full-source shortest path problem. Single-source shortest path refers to the shortest distance from a single source point to all other vertices. The all-to-all shortest path problem refers to the shortest path strength problem between all vertices. In addition, there is no Faste

The previous article has almost detailed the quartz2d of all the knowledge, this and the following is not nonsense, mainly with concrete examples to demonstrate the effect of the drawing.Here we first draw some simple graphs (such as lines, triangles, circles, rectangles, text, images), which can be drawn in two ways, one through context and the other through a path. The following is a demonstration of drawing triangles in two ways.to draw a basic gra

For example, the red edge in Figure 3, Figure 4, is the match of Figure 2.We define matching points , matching edges , unmatched points , mismatched edges , and they are very obvious. Example 3, 1, 4, 5, 7 is the matching point, the other vertices are unmatched points, 1-5, 4-7 is the matching edge, the other edges are non-matching edges.Maximum match : A match with the largest number of matched edges in all matches of a graph, called the maximum match for this graph.

Kruskal AlgorithmOne of the algorithms of the minimum spanning tree of graphs, using and checking the idea to find the minimum spanning tree.The basic idea is to sort all the edges from small to large, traversing the edges in turn. If the two points connected by this edge are in a connected block, traverse the next edge, and if not, add this edge to the connected block so that the Benquan of the spanning tree can be minimized.We use and check the set

Breadth-First traversal (Breadth-first traverse,bfts), called breadth-first search, is a traversal strategy for connected graphs. It is called the breadth-first traversal because his mind begins with a vertex V0, radiating the first to traverse the wider area around it.Algorithm description Given figure g= (v,e).
