WebAn Eulerian cycle is a closed walk that uses every edge of G G exactly once. If G G has an Eulerian cycle, we say that G G is Eulerian. If we weaken the requirement, and do not require the walk to be closed, we call it an Euler path, and if a graph G G has an Eulerian path but not an Eulerian cycle, we say G G is semi-Eulerian 🔗 WebJun 29, 2024 · For example, the formal definition of a walk in a simple graph is a virtually the same as the Definition 9.2.1 of a walk in a digraph: Definition 11.8.1.
