An example of a common definition of the graph (the graph is in fact artificial) which has 3 vertices and 6 lines connected graph G is basically
pair G rating = (V, V E) is a set of vertices and E is the set of links that are not top of the vertex is in fact the definition is just one type of graph known as the graph does not indicate direction and a simple graph is
.Other types of graphs are the details of the set (E) differs, for example, note that the above definition it is not possible to connect two lines in the graph line that connects the two vertices in the same way, because E is a set. If you change the E to become multi-set will be what is called the multi graph or regular graph, graph, instead of artificial. Multiple welding line by line that connects the two vertices of the same point or parallel connection line called.
For the various types of graphs that are more complete, please see below
.At the end of the vertex connecting line is called a vertex at the end of the line. But vertex might not be the end of the vertex (in cases where there is no vertex welding line come here!)
.V & E is usually a set limit, although it is possible that V is nan or E-collar, but several definitions are not allowed in the case of the graph is | | V (vertex) portion of the graph size is | E |-(number of welding line) In the case of the two sides at the end of the welding wire are plugged into the same amount of points, called a loop (blue link border by image on the right), it increased for 1 2 step level band XI
.
Welding line {u, v} may be written, short which uv.
