Data Structure --- using C ++ to implement cross-linked list storage and representation of Graphs
I have been busy with postgraduate review recently and haven't updated my blog for a long time. Today I am writing a piece of data structure storage.

Use the Hungary algorithm to obtain the maximum matching of binary graphs.

What is a bipartite graph and what is the maximum matching of a bipartite graph? I will not talk about these definitions. I can find them on the Internet. Two methods are available for the maximum matching of a bipartite graph. The first method is the largest stream (I suppose the reader already has knowledge about the network stream), and the second

coding point of view is as follows: TCP communication requires server-side listening Listen, receiving client connection request accept, waiting for client connect to establish a connection before sending and receiving packets (recv/send). However, the concept of UDP server and client is not obvious, the server side is the receiving end need to bind the port, waiting for the arrival of the client's data. Subsequent data can be sent and received (RECVFROM/SENDTO) work. Reference: http://blog.

When encountering this problem, it is not easy to think quickly, it may be easier to think of the idea of recursion;But how exactly do you write it?In fact, this problem is equivalent to the graph theory in the connection graph, it is easy to think of is depth-first search or breadth-first search;We use the depth-first algorithm to find the problem;Directly ask for a few areas are not good, then we change a way to beg, this problem is so, direct beg, but when we switch ideas after the enlightene

In addition to the simplest drawing curve function I used above, it has other very powerful features, as shown in: It contains many examples of many kinds of chart drawing, which can be used by the program apes to achieve a variety of data visualization operations. But I do not know why, Lightningchart this powerful. NET component in the network introduction is very few, to me

Algorithms for basic graphsG= (V,e)notation, adjacency Matrix, adjacency list (sloppy view)The adjacency list represents a containing | An array of v| linked lists Adj, each node has a linked list. For each node u belongs to V, the adjacency list Adj[u] contains all theJunction U has a node v connected to the node.Weight graph, with a related weight for each edge in the graph.The weight function w:e->r.The adjacency list flaw is the inability to quickly determine whether an edge (u,v) is an edge
