This article mainly introduces the JavaScript data structure and algorithm diagram and graph algorithm. This article describes the directed graph, unordered graph, simple graph, and graph traversal. For more information, see Graph

1. Basic Concepts: Ordered graphs, each vertex has a precursor and a successor relationship. In real life, we can use a direction diagram to represent a project, the vertex table is an activity, a---------->b says: A must be preceded by activity B. This kind of graph is called the "Top expression activity network (active on vertices)" --As a AOV network. All vertices are sorted in a linear order sequence. The operation of the topological ordered seque

Graph Theory and network science involve a large amount of statistical computing on the characteristics of graphs. Generally, statistics, mining, and visualization related to graph data are collectively referred to as graph processing. This series of articles mainly want to explore various graph processing theories and

ObjectiveIn this section we will delve into the main optimization methods in visual slam-graph optimization (graph-based optimization). In the next section, we describe a very popular graph optimization library: G2O.As for G2O, I wrote a document in 13, but as I deepened my understanding, I felt more dissatisfied. In the spirit of more responsible for the reader,

Graph Theory conclusion, Graph Theory AlgorithmThe connectivity of a graph has a point with a unique degree of 0 in a non-ring graph, which can be reached by any point (because of the absence of a ring, we can start from any point and go forward, must end at a point with an outbound degree of 0.) any point with a non-I

a simple concept of the main record stream network and the maximum flow ( The implementation algorithm of the maximum flow may be supplemented later ) , the main explanation is to use the Hungarian algorithm to find the maximum matching of the binary graph. 1 : Streaming Network Stream network is g (V, E) is a finite graph, each of its sides (U, v) ∈ e c (U, v) ≥ 0 (U, v) e C (U, v) = 0

Since I have never studied Discrete Mathematics, I can only make an axe to the class here: A graph G = (V, E) is composed of vertex set V (vertex) and edge set E (EGGE. Each edge is a point (V, W), where V, W, V. If the point-to-point is ordered, the graph is directed, otherwise it becomes an undirected graph. If two vertices (V1, V2) and E are associated, they a

Bipartite Graph learning summary, Bipartite Graph Summary Match: In graph theory, a match is a set of edges, and any two edges have no common vertices. Max matching: The maximum number of matching edges in a graph. Maximum number of matches: Maximum number of matched Edges Perfect match: If all vertices in a matchi

On the basis of an undirected graph, a directed graph can be implemented by slight modification: 1) Public void addedge (INT start, int end) In an undirected graph, you need to call private void addedgetovnodelist (vnode node, edge) twice to add edges to the edge linked list of the two endpoints. In the directed graph,
