Across
- 1. a walk with no repeated vertices
- 4. a walk that has no repeated edges
- 5. closed trail; a trail where start and end point are the same vertex
- 7. when the start point and end point are the same vertex
- 9. a graph where there is an x-y path for all vertices
- 12. order doesn't matter
- 14. vertex with no edges
Down
- 2. edges connected to a vertex
- 3. order matters; has a tail and head where the tail points to the head
- 6. two vertices connected by an edge
- 8. loop-free, undirected, and with no multiple edges
- 10. theory a collection of vertices and edges
- 11. a sequence of vertices and edges
- 13. closedpath; a path that starts and ends at the same vertex
