## What is a example of a disconnected graph?

A graph is disconnected if at least two vertices of the graph are not connected by a path. If a graph G is disconnected, then every maximal connected subgraph of G is called a connected component of the graph G….Disconnected Graph.

Vertex 1 | Vertex 2 | PATH |

**What is a disconnected graph?**

A graph where the vertices separate into two or more distinct groups, where you cannot link a vertex in one group to a vertex in another by travelling along a series of edges.

**What is a disconnected graph in graph theory?**

A graph is said to be disconnected if it is not connected, i.e., if there exist two nodes in such that no path in has those nodes as endpoints.

### Can a simple graph be disconnected?

A simple graph, also called a strict graph (Tutte 1998, p. A simple graph may be either connected or disconnected. Unless stated otherwise, the unqualified term “graph” usually refers to a simple graph. A simple graph with multiple edges is sometimes called a multigraph (Skiena 1990, p.

**How do you determine if a graph is connected or disconnected?**

A graph is said to be connected if every pair of vertices in the graph is connected. This means that there is a path between every pair of vertices. An undirected graph that is not connected is called disconnected.

**How do you tell if a graph is connected or disconnected?**

#### Is the graph connected or disconnected?

**Can undirected graph be disconnected?**

An undirected graph that is not connected is called disconnected. An undirected graph G is therefore disconnected if there exist two vertices in G such that no path in G has these vertices as endpoints. A graph with just one vertex is connected. An edgeless graph with two or more vertices is disconnected.

**What is complete graph with example?**

A complete graph is a graph that has an edge between every single vertex in the graph; we represent a complete graph with n vertices using the symbol Kn. Therefore, the first example is the complete graph K7, and the second example isn’t a complete graph at all.

## Can a disconnected graph be planar?

First of all there is no relation between concept of planarity & concept of connected & disconnected graph. Given disconnected graph, you can not call it either planar or non planar.

**Can a BFS work on a disconnected graph?**

But in the case of disconnected graph or any vertex that is unreachable from all vertex, the previous implementation will not give the desired output, so in this post, a modification is done in BFS. All vertices are reachable. So, for above graph simple BFS will work.
