Types of Graphs
Explore different types of graphs, including directed and undirected, weighted and unweighted, as well as cyclic and acyclic graphs. Understand their characteristics, use cases, and how to implement these graphs in C++, helping you grasp fundamental concepts necessary for solving graph-related problems.
Graphs can be classified into different types based on how their edges behave. The most common classifications are:
Directed vs. undirected
Weighted vs. unweighted
Cyclic vs. acyclic
Directed graphs
A directed graph, or digraph, is a graph in which each edge has a direction. This means the connection goes from one vertex to another in a specific direction.
For example, if there is an edge from A to B, that does not automatically mean there is an edge from B to A.
A directed graph can be shown like this:
When directed graphs are useful
Directed graphs are used when relationships are one-way. Some common examples include: ...
