congrats on reading the definition of directed walk . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test A directed walk can traverse any vertex or edge multiple times. The direction of the edges must be followed strictly in a directed walk. A directed walk may start and end at the same vertex, forming a closed walk. Directed walks are used to explore networks like social media connections or web page links. In formal terms, a directed walk is represented as an alternating sequence of vertices and directed edges. Review Questions What distinguishes a directed walk from an undirected walk? Can a directed walk revisit the same vertex or edge? Explain.
