Short Answers. Section 14.1. **Graph** Definitions. Draw a **directed** **graph** with five **vertices** and seven edges. Exactly one of the edges should be a loop, and do not have any multiple edges. Draw an undirected **graph** with five edges and four **vertices**. The **vertices** should be called v1, v2, v3 and v4--and there must be a path of length three from v1 to. therefore, the complete digraph is a **directed** **graph** in which every pair of distinct **vertices** is connected by a pair of unique edges (one in each direction). The complete **graph** **on** **n** **vertices** is denoted by K **n**. K **n** has n(n−1)/2 edges and is a regular **graph** of degree n−1. Undirected **Graph**. The connected **graph** is called an undirected **graph**, which has at least one path between each pair of **vertices**. The **graph** that is connected by three **vertices** is called 1-vertex connected **graph** since the removal of any of the **vertices** will lead to disconnection of the **graph**.

**How** **many** **directed** **graph** exist on K **vertices**? My answer: Choose any one vertex out of the K possible choices, the for each of these K **vertices** we could choice first there are a possible K − 1 **vertices** that it could direct to. For each of these K − 1 possibilites there are two choices, it either has a **directed** edge between it or not. each edge is preceded and followed by its endpoints Simple cycle cycle such that all its **vertices** and edges are distinct Examples C1=(V,b,X,g,Y,f,W,c,U,a, ) is a simple cycle C2=(U,c,W,e,X,g,Y,f,W,d,V,a, ) is a cycle that is not simple Edges can be dropped if no multiple edges exist. C1 U X V W Z Y a c b e d f g C2 h.

3 edges (**graph** 7-8-9-10): There are 4 possible **graphs**. A triangle that forms a loop (**graph** 7), a triangle with one vertex not being a terminal vertex (**graph** 8), two edges between one pair of **vertices** and another **directed** edge pointing away from the pair of edges (**graph** 9) and two edges between one pair of **vertices** and another **directed** edge toward the pair of edges (**graph** 9). therefore, the complete digraph is a **directed** **graph** in which every pair of distinct **vertices** is connected by a pair of unique edges (one in each direction). The complete **graph** **on** **n** **vertices** is denoted by K **n**. K **n** has n(n−1)/2 edges and is a regular **graph** of degree n−1.

The need to determine the structure of a **graph** arises in **many** applications. This paper studies **directed** **graphs** and defines the notions of $$\ell$$ -chained and $$\{\ell ,k\}$$ -chained **directed** **graphs**. These notions reveal structural properties of **directed** **graphs** that shed light on **how** the nodes of the **graph** are connected.

The maximum # of nodes it can point to, or edges, at. We'll start with **directed** **graphs**, and then move to show some special cases that are related to undirected **graphs**. As we can see, there are 5 simple paths between **vertices** 1 and 4: Note that the path is not simple because it contains a cycle — vertex 4 appears two times in the sequence. 3.

The **graph** C **n** is 2-regular. Therefore C **n** is (**n** 3)-regular. Now, the **graph** **N** **n** is 0-regular and the **graphs** P **n** and C **n** are not regular at all. So no matches so far. The only complete **graph** with the same number of **vertices** as C **n** is **n** 1-regular. For **n** even, the **graph** K **n** 2;n 2 does have the same number of **vertices** as C **n**, but it is n-regular.

I got this qustion in a test, the answer says **N** * 2^((N-1)*(N-2)/2), because for each of the **N** **vertices**, it calculates the number of undirected **graphs** with N-1 **vertices**. But I think this answer is wrong. For N=3 it results 6, when, in fact, only 4 out of the 8 possible **graphs** have at least one isolated vertex. So, am I wrong?.
