Vertices and edges
Multiple edges. Loops
Undirected Graph
Directed Graph
Simple Graph
The graph doesn’t have multiple edges
Complete and Bipartite Graphs
Complete Graph
All of the nodes in the Graph are
connected each other.
Bipartite GraphThe nodes in the graph are
divided into two classes. Edges exist only between nodes of
different classes.
Path in Undirected Graphs
Simple path. The sub-graph is connected and has two first-degree nodes (0 and 6). The
other nodes of the sub-graph are second-degree.
Path in Directed Graphs
Simple path. The sub-graph is connected and has one zero-indegree source node (0), and one zero-outdegree destination node (5). The other nodes of the sub-graph are second-degree
(1 in/out degree).
Hamilton Path in Undirected Graphs
The subgraph is a simple path which spans all of the nodes in
the graph
Hamilton Path in Directed Graphs
The subgraph is a simple path which spans all of the nodes in
the graph
Cycle in Undirected Graphs
The bold subgraph above is connected and its vertices are
second-degree.
Cycle in Directed Graphs
The subgraph is connected and its vertices are 1 indegree and 1
outdegree
Hamilton Cycle in Undirected Graphs
The subgraph is a simple cycle which includes all of the nodes
in the graph
Hamilton Cycle in Directed Graphs
The subgraph is a simple cycle which includes all of the nodes
in the graph
Cyclic and Acyclic Digraphs
Cyclic GraphThe graph contains
cycles
Acyclic GraphThe graph does not contain
cycles
Tree
The subgraph is a path which is a tree

Strongly Connected Digraph
The graph is connected. All of the nodes in the graph are
strongly connected each other.
