, matching edges , unmatched points , mismatched edges , and they are very obvious. Example 3, 1, 4, 5, 7 is the matching point, the other vertices are unmatched points, 1-5, 4-7 is the matching edge, the other edges are non-matching edges. Maximum match : A match with the largest number of matched edges in all matches of a graph, called the maximum match for this graph. Figure 4 is a maximum match that contains 4 matching edges.Perfect Match : if one of the

The graphs are primarily depth-first traversal (DFS) and breadth-first traversal (BFS).1 Depth-First traversal--dfsThe depth preference is similar to the first sequence traversal of a tree, starting from the node to be accessed (0), selecting any node adjacent to it (3), accessing it, then accessing it, and 3 adjacent nodes (4), accessing it until it accesses a node that has no neighboring nodes, such as 4 without adjacent nodes, then backtracking one

This problem compared to the pain, originally five map corresponding to five small squares, now more run out of two graphs, need to be modified, because the previous code understanding is not deep, so the change is always not, I always want to put the small box for the parameter I in the loop directly to the picture, for(varI=0, olen=oa.length;i) {Oa

The number group records the coordinates of the first point of each point belonging to the connected block, and then writes a bunch of them.Later asked a great God, like the mist to see the s

first, the basic terminologyFigure: Consists of a poor, non-empty point set and a set of edges, which is simply written in G (V,e);Vertex: The vertex in the graph: there is no direction for each edge in the graph: there is a direction in each edge of the graph; no edge: The Edge is no direction, and is written as (A, B) has a forward edge: The edge is a direction, is written as an edge is also an arc; the beginning vertex is called the arc tail;Simple diagram: There is no graph pointing to itsel

Application of graphs-the implementation of searchThe search of the graph mainly includes two kinds of 1 are depth first search, one is breadth first search. Depth-First search as the name implies is always far away from the source search point, search down, depth-first search mechanism is a stack to achieve, breadth-first search algorithm is implemented by the queue, because the implementation of the mechanism is different, so the way to search is al

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
