Translated from jelline BlogHttp://blog.chinaunix.net/uid-9112803-id-411340.html//==============================In the process of doing research, we found that the mathematical model or the graph theory model, which used to feel useless, suddenly became very useful. Sigh at their own knowledge of the deficiencies, so search for relevant knowledge to learn, and share.This reprinted article has certain help for the junior personnel who are engaged in th

Recently in the chapter on the graph theory of discrete mathematics, here is my classification and summary of some important concepts of the graph. Describe the concept of relationships Association--used to describe the relationship between a point and an edge, which simply means that the edge is made up of those points and is associated with those points. The correlation matrix is a matrix that records

This object is used to control the filter graph and supports igraphbuilder, imediacontrol, imediaeventex, and many other interfaces. All DirectShow applications need to use this object in som

Graph Visualization Library in JavaScriptI ' ve just put together what's be looking for:http://www.graphdracula.netIt ' s JavaScript with directed graph layouting, SVG and can even drag the nodes around. Still needs some tweaking, but is totally usable. You create nodes and edges easily with JavaScript code like this:var g = new Graph();g.addEdge("strawberry", "c

Traversal of graphs Graph traversal (traversing graph): from one vertex of the graph, visit the remaining vertices in the diagram, and each vertex is only accessed once.The traversal algorithm of graphs is the basis of operation of various graphs. However, the traversal of the diagram has the following characteristics:Complexity: Any vertex of the

Looking for a standard to study a bit, modified into their own style, paste it up. Reference: KM algorithm by giving each vertex a label (called the top mark) to the problem of finding the maximum right matching to the problem of complete matching. The top mark of the Vertex XI is a[i], the top mark of the vertex Yi is b [i], and the Benquan between the Vertex XI and the YJ is w[i,j]. At any point in the algorithm execution, A[i]+b[j]>=w[i,j] is always true for either edge (I,J). Km the correct

Objective Many friends may have the understanding that Visual FoxPro has limited support for Graph objects-it's hard to use it to make rich, beautiful icons; there are some problems that seem insurmountable: print charts--visual FoxPro does not provide a way to print a form, graph Does not provide a way to print or Save as a picture ... I have this idea, but with the gradual establishment of "object-orien

Before trying to learn Coursera on Markov with the airport courses, found that do not understand, the reason is that the guy came up with a brief introduction of Markov with the airport is what it began to graphcut. But what exactly is Markov with the airport. Why Markov can be defined and deduced in the same way as the airport. None of this was clear, so he listened to a muddle. This system has learned the probability diagram, has the clearer understanding to this question, here briefly discuss

Liu rujia's book on this chapter is also similar. When I was doing the question, I found that I had a lot of knowledge and thinking in graph theory. So I went to the library and borrowed two graph theory books, some notes are organized here. I. Important ideas:1. Makeup:--G is a graph of a V (G) point set, but the two points are connected in G only when they are

Introduction to adjacency matrices Directly, the adjacency matrix is a storage structure of graphs . So what's the picture? A diagram is a logical structure that, like a linear structure, a tree structure, and a collection structure, is a logical structure used to describe the relationship between data elements in a data object . Take a look at the definition of the graph: a graph is a set of vertices that

Two-part graph matchinggiven a two-part graph G ( no map ) , in G a sub-diagram of M in which M any two edges in the edge set are not attached to the same vertex, it is said M is a match .Choosing The largest subset of such edges is called the maximum matching problem for graphs (maximal matchingproblem) If one match, each vertex in the diagram is associated with an edge in the

connectivity issues for graphs: the connected component and spanning tree of undirected graphs, all vertices are by edges connected together, but There is no diagram of the loop. Figure g= (V, E) is a connected graph that divides the edge set E (g) into two sets of T (g) and B (g) When traversing the graph G from any vertex of the graph. where T (g) is the set of
