## What is graph theory in discrete mathematics?

## Is graph theory applied to mathematics?

Since its origins in the 18th century, graph theory has been **a branch o mathematics** that is both motivated by and applied to real world problems. Research in discrete mathematics increased in the latter half of the twentieth century mainly due to development of digital computers.

## What is graph in graph theory?

A graph is **a collection of vertices, or nodes, and edges between some or all of the vertices**. When there exists a path that traverses each edge exactly once such that the path begins and ends at the same vertex, the path is known as an Eulerian circuit and the graph is known as an Eulerian graph.

## What is graph explain with example?

A graph is **a common data structure that consists of a finite set of nodes (or vertices) and a set of edges connecting them**. ... For example, a single user in Facebook can be represented as a node (vertex) while their connection with others can be represented as an edge between nodes.

## What is graph theory used for?

Graph Theory is ultimately **the study of relationships** . Given a set of nodes & connections, which can abstract anything from city layouts to computer data, graph theory provides a helpful tool to quantify & simplify the many moving parts of dynamic systems.Aug 12, 2020
