Nettet24. mar. 2024 · The length of a walk is its number of edges. A u,v-walk is a walk with first vertex u and last vertex v, where u and v are known as the endpoints. Every u,v-walk contains a u,v-graph path (West 2000, p. 21). A walk is said to be closed if its endpoints are the same. The number of (undirected) closed k-walks in a...
