What is Directed Acyclic Graph?

A Directed Acyclic Graph (DAG) is a directed graph that does not contain any cycles.

Below Graph represents a Directed Acyclic Graph (DAG):

Direct Acyclic Graph

Meaning of Directed Acyclic Graph:

Directed Acyclic Graph has two important features:

  • Directed Edges: In Directed Acyclic Graph, each edge has a direction, meaning it goes from one vertex (node) to another. This direction signifies a one-way relationship or dependency between nodes.
  • Acyclic: The term “acyclic” indicates that there are no cycles or closed loops within the graph. In other words, you cannot traverse a sequence of directed edges and return to the same node, following the edge directions. Formation of cycles is prohibited in DAG. Hence this characteristic is essential.

Introduction to Directed Acyclic Graph

A Directed Acyclic Graph, often abbreviated as DAG, is a fundamental concept in graph theory. DAGs are used to show how things are related or depend on each other in a clear and organized way. In this article, we are going to learn about Directed Acyclic Graph, its properties, and application in real life.
