# Does BFS work on acyclic graphs?

## Does BFS work on acyclic graphs?

Also,a line of nodes as such 1 -> 2 -> 3 -> 4 can be considered as a Directed Acyclic Graph, correct? BFS can be used on any graph by coloring the visited nodes. BFS is used to find the shortest path from one node to any other node in a graph. This has nothing to do with finding a simple path that visits every node.

## Does BFS work on directed graphs?

BFS and DFS in directed graphs For directed graphs, too, we can prove nice properties of the BFS and DFS tree that help to classify the edges of the graph. For BFS in directed graphs, each edge of the graph either connects two vertices at the same level, goes down exactly one level, or goes up any number of levels.

**Does DFS work on directed graphs?**

Depth First Search (DFS) is a systematic way of visiting the nodes of either a directed or an undirected graph. As with breadth first search, DFS has a lot of applications in many problems in Graph Theory. It comprises the main part of many graph algorithms. DFS visits the vertices of a graph in the following manner.

### Is topological sort BFS or DFS?

Topological Sorting can be done by both DFS as well as BFS,this post however is concerned with the BFS approach of topological sorting popularly know as Khan’s Algorithm.

### What is Kahn’s algorithm?

Topological sorting for Directed Acyclic Graph (DAG) is a linear ordering of vertices such that for every directed edge uv, vertex u comes before v in the ordering.

**What is Breadth First Search BFS )? Explain with suitable example?**

Breadth-first search (BFS) is an algorithm that is used to graph data or searching tree or traversing structures. The full form of BFS is the Breadth-first search. The algorithm efficiently visits and marks all the key nodes in a graph in an accurate breadthwise fashion.

#### When the breadth first search of a graph is unique?

When the Breadth First Search of a graph is unique? Explanation: When Every node will have one successor then the Breadth First Search is unique.
