Recently, looking at some algorithms, we need to show the data structure of the abstract graph in a visual way, I thought matplotlib might have potential support, and found a module networkx about the calculation and display of graphs. This module is very convenient to use, support dict based adjacency table, to assist graph theory learning is very good. #-*-encoding:utf-8-*- fromMatplotlibImportPyplot as PltImportNetworkx as NxN= { 'a': {'b','C','

Adjacency table is a chain storage structure of graphs. In the adjacency table, a single linked list is established for each fixed point in the diagram, and the nodes in the I single-linked list represent the edges attached to the fixed-point VI. Each node is composed of three domains, table nodes, head nodes, and storage graphs.If the structure of a diagram like a buildThen the procedure is as follows:#include adjacency table Storage for

Talk: Recently Ching Ming small holiday, a good relaxed a bit. Both before and after the festival are a bit lax. Not good, bad. You are insisting. Come on.The adjacency matrix representation of graphs is to represent the data structure of a graph with two arrays. One is a vertex array and the other is an array of adjacency matrices. The relationship that holds vertices in the adjacency matrix.It is simpler to use the adjacency matrix to represent the

Original address: 77431043First, explainIn the graph G, if there is at least one mutually accessible path between the two vertices, the two vertices are strongly connected (strongly connected). If there is strong connectivity to every two vertices of the graph G, the G is a strongly connected graph. The strongly connected sub-graph of the undirected graph of non-strong connected graphs is called the strong connected component (strongly connected compo

Minimum spanning tree to ask:The data are given as follows:The first line has two numbers, n represents n cities, m represents M roads, and the next M row, three numbers per row a,b,c represents city A to City B's distance C.What needs to be solved now is to require a minimum of Bentour-Guenton (any two points can be reached between each other). To connect the graphs of n vertices, you need to n-1 at least one edge. In fact, this is the smallest spann

While good color schemes are now handy, it's still hard to find the right color scheme for data visualization. Because of the unique attributes of the information map, it is necessary to satisfy the rich and not messy color matching requirements while ensuring the clarity of color recognition. However, even if you are not sensitive to color, with today's dry goods mentioned in the 3 tips, you can easily create a good-looking information map. In the case of information

First, the problem introducedThe problem of judging the number of graphs is often encountered on the network, as the following example:If we are going to select all the triangles in the graph, how do we use the code to determine if the graph we selected is a triangle, given each intersection. For example, how to filter out Figure 3?There are two steps to be used here:1. Get the vertex collection of all the small shapes contained in the selected graph

I have been leafing through this article recently.

In R language, the common graphs are histogram, box line, bar, dot matrix, pie chart, QQ chart. 1. Histogram Histogram is a visual understanding of the data distribution of the commonly used graphics, it divides the continuous data into equal spacing groups, and the height of the rectangle to display the corresponding group of data contained in the number or frequency of the size, sometimes can display the density curve of the data as auxiliary. This

This article mainly introduces how to use matplotlib of Python to draw data graphs in Linux. matplotlib is an extension of Scientific Computing Based on Numpy, if you want to obtain an efficient, automated, and high-quality scientific drawing solution in Linxu, you should try the matplotlib library. Matplotlib is an open source scientific ing package based on python and is released based on the python Software Foundation license. A large number of doc

Storage structure of graphs (adjacency matrices)Let programming change the worldThe Storage structure of graphsThe storage structure of graphs is much more complex than linear tables and trees.We look back, for linear tables, is a one-to-one relationship, so with arrays or linked lists can be easily stored. The tree structure is a one-to-many relationship, so we want to combine the attributes of the a

I. Depth-first traversal is a traversal strategy for connected graphs. The basic ideas are as follows:Set X is the currently visited vertex, and after the access mark has been made to X, select an undetected Edge (x, y) that departs from X. If vertex y is found to have been visited, re-select an undetected edge from X, otherwise along the edge (x, y) to the never visited Y, access to Y and mark it as visited, and then search from Y until all the paths

The nature of the dichotomy: in the graph G, there must be at least two points.
