WebIn other words, a walk is a sequence of edges joining a sequence of vertices. There are different names for different types of walks. A closed walk in a directed graph starts and ends at the same vertex. For example, going from vertex 1 to vertex 2 and back to vertex 1 is a closed walk because the walk started at vertex 1 and ended at vertex 1. WebIn general, the edges and vertices may appear in the sequence more than once. If v1 = vk + 1, the walk is a closed walk or a circuit . We will deal first with the case in which the walk is to start and end at the same place. A successful walk in Königsberg corresponds to a closed walk in the graph in which every edge is used exactly once.

WebThe walk is closed if v1 = vn, and it is open otherwise. An infinite walk is a sequence of edges of the same type described here, but with no first or last vertex, and a semi-infinite walk (or ray) has a first vertex but no last vertex. A trail is … WebA walk is closed if it has positive length (defined as its number of edges) and its origin and terminus are the same (vertex). A closed trail whose origin and internal vertices are distinct is a cycle. SUMMARY: So in this system of definitions, a cycle cannot repeat edges or vertices except the origin/terminus, which excludes walks of length two.
