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 worth not

1. Summary Because of the complex pattern and different information descriptions of graph databases, it is extremely difficult for non-professional users to query complex graph databases. A Good Graph query engine should support conversion of synonyms, acronyms, abbreviations, and ontology, and should be able to sort search results well. Based on this problem, th

First, let's introduce it with one question. For details, refer to [linear planning and network flow 24 Question 2] space flight plan questions. In this question, the experiment depends on the instrument, and both the experiment and the instrument have the right value, and the instrument is negative, and the experiment is positive. Here, the concept of closed graphs is very good. In a graph, we select some vertices to form a set, which are marked as V

Taken from 1976 Ullmann Part2Naive alogrithm for subgraph isomorphism.1. How to determine the isomorphism of the sub-graph.There is a gα and gβ, Gα has pa points, QA edge, Gβ has a PB point, QB Bar edge. A is the adjacency matrix of Gα, and the corresponding B is the adjacency matrix of gβ. So how to judge isomorphism. Set A is a sub-image, B is the original. Then there is a mapping of points to B of point A. The pattern of this mapping is called M. M is the PA row, PB column. One of the propert

Brief: The Bellman-ford algorithm still calculates the shortest path algorithm from one point to all other points , its time complexity is O (NE), n is the number of points, and E is the amount of edges, it is not difficult to see, when a graph is slightly denser, The number of edges will be more than points then the efficiency is actually lower than the Dijkstra algorithm. However, this algorithm can calculate the existence of negative right side (no

Breadth-First traversalBreadth-first traversal is a very common and common way to traverse a graph, except for BFS and DFS, which is the depth-first traversal method, which I will write in my next blog post.Traversal processI believe that every person who read this blog can read the adjacency list storage diagram.Do not understand the person, please first learn the storage method. In my previous blog.Portal: Diagram Representation methodThen we assume

The application of graphs is probably the broadest of all data structures, but this is doomed to speak of "data structure of the graph" when there is nothing to say-the most important thing about the graph is the algorithm, and a considerable part is very professional, the general people almost will not touch, relatively, the structure appears to be very light weight. You can see that there are very few ope

The first section, depth and breadth first refers to whatFor the traversal of the graph.The main idea of depth-first traversal is to traverse one of the branches of the graph until the end, then back up, and then do the same traversal along another line until all the vertices have been accessed.The main idea of breadth-first traversal is to first access all of its adjacent vertices with an unused vertex, and then to each adjacent vertex, and then acce
