## Eulerian circuit definition

Paths traversing all the bridges (or, in more generality, paths traversing all the edges of the underlying graph) are known as Eulerian paths, and Eulerian paths which start and end at the same place are called Eulerian circuits.When \(\textbf{G}\) is eulerian, a sequence satisfying these three conditions is called an eulerian circuit. A sequence of vertices \((x_0,x_1,…,x_t)\) is called a circuit when it satisfies only the first two of these conditions. Note that a sequence consisting of a single vertex is a circuit.
