WebHere, we'll see three ways to represent graphs. We'll look at three criteria. One is how much memory, or space, we need in each representation. We'll use asymptotic notation for that. Yes, we can use asymptotic notation for purposes other than expressing running times! WebMar 29, 2024 · A directed graph is a graph in which edges have orientation (given by the arrowhead). This means that an edge (u, v) is not identical to edge (v, u). An example could be nodes representing people and edges as a gift from one person to another. An undirected graph is a graph in which edges don't have orientation (no arrowhead).

Webdirected graph is strongly connected if all vertices are reachable from all other vertices. Cycles. In a directed graph a cycle is a path that starts and ends at the same vertex. A cycle can have length one (i.e. a self loop). A simple cycle is a cycle that has no repeated vertices other than the start and end vertices being the same.
