Original question: Graph is a collection of edges E and vertices v. Graph have a wide variety of applications in computer. There is different ways to represent graph in computer. It can be represented by adjacency matrix or by adjacency list. There is some other ways to represent graph. One of them is to write the degr

Tree (free tree), unordered tree, and root treeFree Treeis a non-loop connected graph (no root is determined) (one of the vertices in the free tree is chosen as the root, then a normal tree).Starting at the root, for each vertex (usually called a node in the tree), the child is left-to-right in order, it becomes aordered Tree。In the application of graphs, we often need to find a sub-graph of a given

Data Flow Graph A data flow chart is also called a data flow chart date flow digoal and DFD. It is a graphical tool that helps you understand and analyze system data flows, it accurately describes the functions, inputs, outputs, and data storage of the system logically, and is an important part of the system logic model. Basic components of a data flow chart Data Stream: It is composed of a set of fixed data, indicating the data flow. It is w

Undirected graph-depth-first and breadth-first algorithms are extremely applied. First, we will introduce the second part of the Algorithms website.AlgorithmsThis book provides online courses. In addition, this course on algorithms shown on Coursera is also very good. Several Representation Methods of an image: This method (Data Structure) is used to represent the graph. This includes the following two req

Starting with 5.0 (API level 21), Android is starting to support vector graphics. What is the vector map and the vector map has any advantages and disadvantages is not covered in this article, the specific reference vector map encyclopedia. But here's the advantage: Holds the least information, the file size is smaller than the bitmap, and the file size is independent of the size of the object arbitrary magnification of vector graphics will not lose details or affect sharpness, because vector

Original question: You is to write a program this tries to find a optimal coloring for a given graph. Colors is applied to the nodes of the graph and the only available Colors is black and white.The coloring of the graph is called optimal if a maximum of nodes are black. The coloring is restricted by the rule, that no, and connected nodes may be black.InputThe

Graphviz-use commands to draw a graph!Introduction Graphviz is a widely used command line drawing software, but it is a drawing software. It is not a cartoon or logo that most people think, but a graph in the mathematical sense ", the common saying is "Relationship Diagram 」. For example, see the following figure: ▲Figure 1: Unix family. One of the demonstration images on the Graphviz official website. It

Contains a total of four connected components. Vertex A, B, C, and D constitu

1. Proves that there is a simple path between each pair of vertices of the connected undirected graph.Proof: Set U and V are two different vertices of the connected undirected graph G = (V, E), because G is connected, so there is at least one path between U and V. Set x0, x1, x2, ..., xn is the vertex sequence of the shortest path in length, where x0 = u and xn = v. This shortest path is simple. To see this, let's say it's not simple. For some I and J

One: Cause(1) on the graph of the algorithm is generally more complex, their own in this area is relatively weak, the first is the graph of storage problems and traversal problems:The storage is divided into two kinds, adjacency matrix and Street table, the traversal is divided into DFS and BFS two kinds, very similar to the binary tree of the first followed traversal and hierarchical traversal.(2) The figu

Test instructionsThere are 2^n cheese, numbered 00 ... 0 to 11.. 1.There is a machine with n switches. Each switch can be set to 0 or 1, or set *. However, there can be a maximum of one switch set in n switches *.Once the machine's switch is turned on, the machine will disinfect the numbered cheese of the state according to the state of the N switches.For example: 111----disinfect the cheese with number 111. Description: * represents 0 or 1. For example: 1*1----disinfect the cheese with numbers

The determination of the dichotomy graphGiven a graph with n vertices. To dye each vertex on the graph, and to make the adjacent vertex colors different.Determine if it can be dyed in up to two colors. The topic guarantees no heavy edges and self-loops.Concept: The problem of coloring the adjacent vertices into different colors is called the shading problem of graphs. The minimum number of colors required t
