Bipartite graphs are an important part of graph theory and are widely used in real life. For example, the problem of matching must be solved by a bipartite graph. However, the application of the bipartite graph is not only used for these intuitive matching problems, but also has many practical problems that can be solved by the nature of the bipartite graph. For example: how to install the least number of cameras in a supermarket to cover the entire s

Tag: the adjacency matrix of graphs represents the array storage of graphs [This is my own study notes, welcome reprint, but please specify the source:http://blog.csdn.net/jesson20121020] An adjacency matrix is a matrix that represents an adjacent relationship between vertices in a vertex. G= (V,e) is a graph with n vertices, if (VI,VJ) is E, the element corresponding to the adjacency mat

In turn, repeat the operation N-1 times until all vertices are added to the spanning tree.Flow of the prim algorithm:Input data:Operation Result:time Complexity O (n^2) , the time complexity of the whole algorithm is reduced to O (MLOGN) If the time complexity of each edge is O (LOGM), and then the adjacency table is used to store the graph. If all edge weights are not equal, the minimum spanning tree is unique.The Kruskal algorithm is a step-by-step approach to mergi
A graph is a flexible data structure that is typically used as a model to define relationships or connections between objects. Objects are represented by vertices ( V ), and relationships or associations between objects are represented by edges () of the graph E .Graphs can be divided into the direction of the graph and the non-direction diagram, generally used G=(V,E) to represent the diagram. An adjacency matrix or adjacency table is often used to d

There
The graph consists of a poor non-empty vertex set V and a side e. Each edge is a point pair (v,w). The data elements in the diagram are called vertices . If the point pair is ordered (the next point of each point is fixed), then the graph is called a forward graph , otherwise there is no graph . The value associated with the edge of the graph is called the weighted value , and the weighted graph is called the Net (network ). Simple concepts related to graphs

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

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
