In a multigraph, no loops are allowed. a pseudograph is a multigraph that is permitted to have loops. a multigraph (in contrast to a simple graph) is a graph which is permitted to have multiple edges (also called parallel edges), that is, edges that have the same end nodes. Pseudo Graph- A graph having no parallel edges but having self loop(s) in it is called as a pseudo graph. Question # 2. 1. A complete graph is also called Full Graph. It can read data in a variety of formats, and allow you to customize the appearance of the graph. V a set of vertices or nodes,; A a multiset of ordered pairs of vertices called directed edges, arcs or arrows. So the differentiating factor is that a multigraph may not have loops, only self-edges. This is a Simple Graph Multigraph Pseudograph Mixed Graph . Pseudographs may also include multiple edges between vertices, so multigraphs are special cases of pseudographs. Directedgraph:A graph that consists of a nonempty set of vertices and a set of directed edges, and Each directed edge is a multigraph (in contrast to a simple graph) is a graph which is permitted to have multiple edges (also called parallel edges), that is, edges that have the same end nodes. consists of a non-empty set of vertices or nodes V and a set of edges E If the degree of each vertex in the graph is two, then it is called a Cycle Graph.
