Graph in iOS development-Quartz2D- What is Quartz2D? Quartz 2D is a two-dimensional Drawing Engine that supports both iOS and Mac systems.Function Quartz 2D can complete the work of drawing graphics: line, triangle, rectangle, arc, draw text draw generate image (image) read generate PDF crop image custom UI control...Quartz2D's value in iOS development To facilitate the construction of a beautiful UI interface, iOS provides the UIKit framework, whi

Since the release of css3, its functions have become very powerful. Many icons that require images have been used in the past. Now, only a few pieces of css code are required. The following are circles, ovans, triangles, and arrow icons created by

Spatial references coordinate systems, projections, datums, ellipsoids-confusing? People are often mixing the above as if they were one and the same, so here's a recapOf them. One of the things you often find people saying is that "my data is inWGS84

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

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

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.

Reproduced from the original address: http://www.cnblogs.com/loveis715/p/5277051.htmlI recently used a graphical database to support a start-up project. In the process of using this kind of graphics database is actually very interesting. So here's a brief introduction to you.The NoSQL database is believed to have been heard. They can often be used to deal with a series of problems that traditional relational databases are difficult to solve. Typically, these NoSQL databases are divided into four

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

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
